Plenary Lecture

The New Age of Orthodontics with New Innovations: Overcoming the Limitations and Charting the Unknown Territories with MSE and Aligner Systems…How Does a Lingual System Fit In?
Prof. Won Moon (Department of Orthodontics, Ajou University School of Medicine, Korea)
[Abstract]

The discipline of orthodontics is going through drastic changes with the advent of new concepts and technologies. Among these, the non-surgical maxillary expansion in mature patients and clear aligner treatment have taken the center stages of the clinical interests. Although numerous research data and successful clinical cases were presented in recent years, there are many unanswered questions, shortcomings, and challenges we must overcome as we learn to adapt these novel treatment concepts. The shortcomings associated with the maxillary expansion and the current aligner systems will be discussed in detail, and potential solutions by the use of bone-borne expander and novel aligner systems will be proposed. The Maxillary Skeletal Expander (MSE) has evolved since 2004, and overcoming its shortcomings will be illustrated through a trouble shooting exercise. Despite the continuous improvements with various aligner systems, there exist many limitations of their applications. A novel aligner concepts designed to overcome these shortcomings will be introduced, and combining these two devices for optimal treatments of difficult cases will be discussed.

Furthermore, many other novel products have been introduced in the market place, with claims of certain advantages over the existing systems. As these new innovations flood the orthodontic world, the obvious question becomes the relevance of the existing system, including the lingual appliances. The world of orthodontics is evolving at a furious speed, and it is easy to lose sight of the fundamental concepts of orthodontic biomechanics. This presentation will shed some light into incorporating the common-sense biomechanics and fundamental principles of orthodontics as we embrace the changes.

Learning Objectives:

  • Overall concept of MSE; differentiating craniofacial and dentoalveolar changes with MSE
  • Proper use and fabrication of MSE; optimal activation protocol based on mechanical and biological considerations
  • Managing challenging cases with MSE and troubleshooting
  • Shortcomings with current aligner systems
  • Novel concepts in aligner systems and future directions
  • Aligner vs Lingual System vs Labial System

Possibilities and Perspectives of Aligner Orthodontics
アライナー治療の展望と可能性
Dr. Hirohide Arimoto (E-smaile International Orthodontics, Japan)
有本 博英先生(イースマイル国際矯正歯科)
[抄録]

舌側矯正とアライナー矯正は、共に目立たない矯正治療として知られているが、その特徴は全く異なる。素材の力学特性、矯正力の発揮様式、治療進行方式などが異なるために、当初、アライナー矯正は単純なケースにしか向かないと考えられてきた。しかし、さまざまなアタッチメントやステージングの工夫によって、現在はほとんどの症例で、アライナー矯正で対応可能となっている。
さらに、アライナーならではの特徴として、装置が歯冠部全体を覆うという特徴がある。これにより、矯正治療途中で起こる咬合干渉を保護しながら治療を進めることができる。これは、ブラケットとワイヤーによる治療にない特徴である。このような特徴は、特に咬合干渉を避けなければいけない歯周病患者の矯正治療において有利である。
本講演では、このようなアライナーならではの特徴を活かした症例について報告するとともに、従来苦手とされる歯体移動や回転の移動についてもどのように対応するかについて報告する。

[Abstract]

Both lingual treatment and clear aligner treatment are known as invisible orthodontic treatments, but their characteristics are quite different. Due to the different mechanical properties of the materials, modes of orthodontic force exertion, and treatment progression methods, aligner orthodontics was initially thought to be suitable only for simple cases. However, through the use of various attachments and staging innovations, clear aligner treatment can now be used in almost all types of orthodontic cases.
In addition, one of the unique features of clear aligners is that the appliance covers the entire crown of the tooth. This allows treatment to proceed while protecting the patient from occlusal interference that may occur during orthodontic treatment. This is a feature not found in multi-bracket treatment. This feature is especially advantageous in orthodontic treatment with periodontal problems, where occlusal interference must be avoided.
In this presentation, we will report a case that take advantage of these unique features of clear aligners, as well as how to deal with bodily tooth movement and rotational movement, which are conventionally considered to be difficult by clear aligner.

Lingual orthodontics in the era of aligners: allies or enemies?
Dr. Giuseppe Scuzzo (E-Line Clinic, University of Ferrara- Orthodontic Department, Italy)
[Abstract]

New digital technologies have changed the way traditional orthodontics is practiced. Excellence in lingual orthodontics is rarely achieved suddenly or spontaneously, considering that great refinement begins at the beginning and continues throughout the treatment. Furthermore, the Clear aligner system has been radically improved in many aspects, but many movements still remain unpredictable, outlining the limits of aligner treatment.
The combination of lingual orthodontics with clear aligners in a “hybrid approach” shows a new and efficient treatment alternative. This solution significantly reduces the overall treatment time and unpredictable movements of the aligners alone.
Furthermore, digital planning through an exclusive software for both Lingual and Hybrid treatment allows you to precisely customize the position of the teeth, the design of the final torque and the coordination of the arches, improving mechanical control allowing highly predictable results with a significant reduction of treatment times

Aims:
Introduce the hybrid concepts and mechanical benefits of the LSW (Lingual Straight Wire) Square Slot Bracket System combined with Clear Aligners
Objectives:
Explain the digitally customized design aspects of complete LSW and Hybrid systems, describing different types of mechanics that can be used combined or individually depending on the difficulty of the case
Learning outcomes
Delegates will learn about the diversity of this lingual / hybrid system and will be able to discuss how this could be introduced into their own clinical practice.

[抄録]

アメリカ矯正歯科医会は一般のメディアに向けて、子供が7歳になったら矯正歯科に行き早期治療の必要性の有無についてコンサルテーションを受けるよう促している。そこには、正常な顎骨の成長を促すようにすることや、永久歯を正しい位置に咬合誘導をさせていくこと、外傷の予防や、悪臭癖の除去、また口唇のバランスを向上させる為としている。現在、私のオフィスで取り組んでいる早期治療の適応症には反対咬合があり、これを付置すると歯の咬耗が起きたり、歯肉退縮、場合によっては歯の喪失も引き起こす。これらの治療は、近年口腔内スキャナーを用いて、将来萌出するであろう永久歯のスペースを確保しつつアライナーを用いたアプローチが始まっている。このプレゼンテーションでは、前歯の反対咬合や、先天的欠如歯を持った症例を交えながらその考え方について述べさせてていただきます。

[Abstract]

The American Association of Orthodontists (AAO) recommends children get their first check-up at the first recognition of an orthodontic problem or at age 7.
Around that age, children have a mix of baby (primary) and permanent teeth. An examination at this age gives the child orthodontist a wealth of information.

The kinds of problems orthodontists may recommend treating while a child still has some baby teeth include: Underbites, Crossbites, Very crowded teeth, Excessively spaced teeth, Extra or missing teeth.

Regardless of how treatment goals are reached, the bottom line is that some orthodontic problems may be easier to correct if they are found and treated early. Waiting until all the permanent teeth have come in, or until facial growth is nearly complete, may make correction of some problems more difficult.

We have been treating anterior crossbite cases and children having missing teeth during mixed dentition. We discuss how to manage those cases treated by Aligner option.

Lingual Straight Wire System with Square Slot Self Ligation Bracket
スクエアスロットセルフライゲーションブラケットを用いたリンガルストレートワイヤー法
Dr. Kyoto Takemoto (E-Line lingual Orthodontic Clinic, Japan)
竹元 京人先生(イーライン矯正歯科)
[抄録]

従来の舌側矯正治療で使われてきたマッシュルームアーチワイヤーは複雑なワイヤーベンディングが必要であり、ブラケット間距離が短いため、歯のコントロールが難しく、矯正力が強くなりすぎる傾向にあった。よって、軽い矯正力で正確な歯のコントロールを実現するためにスクエアスロットであるALIASによるリンガルストレートワイヤー法を開発した。
ALIAS には 3つの新しい概念がある。
1. 正方形のスロットにより、歯の動きをより細かくコントロールできるため、治療をより正確に計画する事ができる。
2. 治療ではストレートアーチワイヤーを使用する。そのためワイヤーベンディングを大幅に減少する事が出来る。
3. パッシブセルフライゲーションシステムを採用することでフリクションが減少し、弱い持続的な矯正力にする事が出来る。
このプレゼンテーションでは、 アリアスリンガルストレートワイヤーシステムを使った理論と症例を詳しく解説する。

[Abstract]

The mushroom arch-wire is mainly used in conventional lingual orthodontic treatment but the complicated wire bending it requires affects both the treatment results and the time spent in the chair. Since the inter bracket distance is short, it becomes difficult to control the teeth and there is a tendency that the correction force becomes too strong. In order to control teeth with a proper orthodontic force, we have developed ALIAS with a square slot bracket for precise teeth control with light orthodontic force.
With ALIAS there are 3 new concepts.
1.Square slot – the square slot gives more control over tooth movement enabling the orthodontist to more accurately predict treatment outcome.
2.Straight wire – treatment employs a plane arch-wire. With brackets bonded accurately and a full size wire the amount of wire bending is very significantly reduced.
3.Passive self-ligation system – employing a passive ligation system reduces friction and light orthodontic force can be employed.
These concepts make for simplified handing from the lingual side, and achieve better treatment. In this presentation, I will explain in detail of the theory and cases using the ALIAS Lingual straight wire system.

The Limits and Possibilities of Aligner Orthodontic Treatment
アライナー型矯正治療における可能性と限界
Dr. Kenji Ojima (Hongo Sakura Orthodontics Tokyo, Japan)
尾島 賢治先生(本郷さくら矯正歯科)
[抄録]

2006年よりマルチブラケットによる矯正治療からアライナー型矯正治療へ推移して現在に至るまで、約 4,000症例のアライナー型矯正治療を行なってきました。マルチブラケット矯正とアライナー型矯正は治療の組み立て方や考え方も大きく異なり、歯の移動のバイオメカニクスを考慮し且つアライナー型装置の特性を最大限に発揮させることでより良い治療結果へ導くことができます。
私がアライナー型矯正治療を開始した16年前と比較して、現在アライナー型矯正治療の適応範囲の可能性は大きく広がったと考えております。現在当院では、外科的矯正治療を除く全ての症例をアライナー型矯正治療単独で治療を行なっています。しかし一方で、あらゆる先生方が新たにアライナー型矯正治療に取り組む中で、予想外の失敗や障害に向かっている現状も耳にします。国内でアライナー型矯正治療のスキルアップ目的に 2014年に立ち上げた日本アライナー矯正歯科研究会を立ち上げ、定期的な勉強会や症例検討会を開催しておりますが、会員の先生方からも多くのそのような報告を受けています。今回は、私の16年間の治療の推移と、現在取り組んでいるアライナー矯正治療の最新トピックを世界の矯正治療の現状などを織り交ぜながら供覧させていただきます。様々な症例ごとにトピックをまとめてアライナー型矯正治療ならではの治療経過をお見せできることを大変嬉しく思っております。
今回、歴史あるこの様な素晴らしい会にお声がけいただきまして、大変感謝しております。宜しくお願い致します。

[Abstract]

Since switching from multi-bracket system orthodontics to treating only with aligners in 2006, I have treated ever 4,000 unique cases. Treatment planning with aligners is significantly different from treatments with MBS, and with proper knowledge of the biomechanics of tooth movement, as well as the unique characteristics of aligner appliances, we are able to reach better and more predictable treatment outcomes.
When I compare the state of aligner orthodontics now with when I began using them 16 years ago, the range of treatable cases has increased dramatically. At our clinic, with the exception of orthognathic surgery, we treat exclusively using aligner appliances. At the same time, I have heard that many doctors making the transition to aligner treatments are meeting unexpected challenges and obstacles on their journey. In 2014, I founded the Japan Academy of Aligner Orthodontics (JAAO) with the objective of raising the overall skill level of aligner orthodontists in Japan. The JAAO hosts regular study groups, small-scale symposia, and case study sessions, and still I hear about the challenges of aligner orthodontic treatments from JAAO regular members. In this presentation, I will first outline the last 16 years of my journey in aligner orthodontics. Then, I will present and discuss the most cutting edge topics in modern aligner orthodontics from around the world. It is a distinct pleasure and an honor to be able to share not only my knowledge and experience, but through my cases display the true possibility of the aligner orthodontic workflow.

My passion for Lingual Orthodontics
私の矯正歯科に対する情熱、リンガルに対する情熱
Dr. Toshiaki Hiro (Hiro Orthodontic Office、Japan)
廣 俊明先生(ひろ矯正歯科)
[抄録]

私が矯正専門医として教育・臨床・研究に携わるようになって38年が、舌側矯正を始めてから35年が経過しました。当時は、リンガルの教科書やセミナーなどは無く、わずか2冊のJCOを片手に舌側矯正を始めました。毎日が試行錯誤の連続でしたが、私は決して諦めませんでした。それは、リンガルは治療期間が長く、ちゃんと治らない、喋れない、舌が痛い、著しい歯根吸収を起こす等々の悪い評判に対する私自身の挑戦でした。私は、問題点を解決すれば、ラビアルと同じ期間で同じ治療結果をリンガルでも得ることが出来ると信じていたからです。私はリンガルについてまわる問題をひとつずつ解決し、これらの目的を達成しましたので、治療結果を第三者に評価して貰うために、EBOやJOBなどのBoard試験を全てリンガルで受験しました。結果は、全症例合格です。さらに、米国Angle矯正歯科学会には、ABOと同じように未治療の症例を持参して、期限内に治療を終了し、合格しています。これらの結果は、リンガルはラビアルと何ら遜色なく治療出来るのだということを証明出来たと思います。
矯正歯科は難しいです。リンガルはラビアルの何倍も難しいですが、私が今まで35年間続けて来られたのは、難しいからです。若い先生達、より簡単な、より楽な道を選ばず、より難しい、より険しい道を選んで下さい。問題が難しければ難しいほど、あなたの矯正専門医としての能力は向上する、私はそう信じます。限られた時間ですが、症例を交えて私の考えをお話させて頂きたいと思います。

[Abstract]

38 years have passed since I began to work as an Orthodontic specialist, 35 years for my Lingual Orthodontic practice. At that time, there were no Lingual textbooks nor seminars, the only thing I could learn Lingual was a couple of JCO issues. My Lingual practice was trial-and-errors every day, but I never gave it up. It was a challenge for myself against the negative rumors that Lingual requires long treatment term, results are not good, provides incredible tongue pain with speech difficulties, and induce severe root resorption. I was sure that I could overcome them by solving problems associated with Lingual. Soon I could obtain quite excellent results with Lingual, so I took the board examinations such as EBO, JOB, M-Orth, etc. in order to get the evaluations by the third parties. The results were perfect, all of my Lingual cases were accepted. Also, I took the exam for Angle society, submitting not yet started cases, same as ABO, and passed it.
I proved that Lingual works same as Labial Orthodontics.
Labial Orthodontics is difficult enough for myself, but Lingual is much difficult than Labial. I have been doing them more than 35 years because they are difficult, and interesting. I would like to leave my message for the younger orthodontists, please do not take easiest way but difficult ones. Struggling with difficult, troublesome problems improve your skills as an Orthodontist. At the congress, I would introduce my practice, presenting some Lingual cases.

Lingual technique:passion – smile of patients
Dr. Didier Fillion (UT Health San Antonio, France)
[Abstract]

Aesthetic and efficiency qualify the lingual technique for a long time.
3D technology, customized appliance and rigor in clinical procedures, also bring accuracy, harmony and optimisation of dental movements.
The torque control during the retraction phase of treatment with extraction requires the proper choice of brackets, archwire, anchorage and direction of force.
Several clinical examples of no friction mechanics will be presented.

Clinical Invited Lecture

Ideal Dental Arches: fundamental concepts and treatment principles relevant for all appliance types
Dr. Will A. Andrews (University of California at San Francisco, USA)
[Abstract]

Despite being the oldest dental specialty, orthodontics remains beleaguered by some very basic questions. Where do the teeth belong within each jaw? When are premolar extractions warranted? Where do the jaws belong? Are we measuring these things the right way? What are the best ways to move teeth and jaws to their intended positions? Something akin to an epiphany occurs when realizing that orthodontic diagnosis, classification, and treatment must be focused on the individual arch rather than the malocclusion. This seemingly simple precept profoundly influences treatment decisions regardless of the appliance used. The parameters of an ideal arch are defined by individual tooth positions (inclination, angulation, rotation, height, and relative prominence) as well as by collective tooth positions (arch width, shape, depth, length, and symmetry). The goals for individual tooth positions can be succinctly summarized by the Six Keys to Optimal Occlusion. Defining goals for collective tooth positions (ideal arches) is where most discord exists among orthodontists. Scientifically supported goals for ideal arches (Element I of the Six Elements of Orofacial Harmony™) will be presented along with methods suitable for achieving them. Idealized dental arches are then the prerequisites for diagnosing and classifying jaw positions in all three planes of space (Elements II-V). Optimal occlusion (Element VI) occurs when arches and jaws are in harmony with each other, with supporting tissues, and with the face.

Prof. Noriaki Yoshida (Nagasaki University, Japan)
吉田 教明先生(長崎大学)
[抄録]

本講演では、バイオメカニクスの観点から、舌側ブラケットシステムと唇側ブラケットシステムにおけるen-masse retraction時の歯の移動パターンを比較検討したいと思います。舌側ブラケットシステムでは、抜歯症例において空隙閉鎖時に切歯のアンコントロールド・ティッピング(制御されない傾斜移動)や垂直および水平方向のボーイングエフェクトなどの副作用が発生します。その結果、長い治療期間を要する可能性もあります。また,歯の舌側面にブラケットを装着することが歯の移動に大きな影響を及ぼすことが知られています。われわれは,有限要素法を用いた長期的な歯の移動シミュレーションシステムを開発し,様々な治療メカニクスを適用した際の歯の移動様相を可視化することが可能となりました。このバイオメカニクス研究により,以下のような様々な臨床上の疑問に対する解答を得ることができます。1.舌側ブラケットシステムでは,なぜボーイングエフェクトが顕著に現れるのか?2. En-masse retraction時において、スライディングメカニクスに組み合わされたパワーアームがどの程度有効なのか?3. スライディングメカニクスとループメカニクスはどちらが有効なのか?4. ワイヤー断面(ホリゾンタル・スロットとバーティカル・スロットにおける力系の違い)の効果は?5.アーチワイヤーに組み込まれたコンペンセーティング・カーブの効果は? 最後に、舌側ブラケットシステムにおける最適な荷重条件について考察を加えたいと思います。

[Abstract]

This presentation will deal with comparison of tooth movement pattern during en-masse retraction when using lingual and labial bracket systems from the perspective of biomechanics. The lingual bracket system generates side effects such as uncontrolled tipping of the incisors, and vertical and horizontal bowing effects during space closure in extraction cases. Consequently, treatment duration could be extended. The placement of brackets on the lingual side of teeth exerts a major influence on the force system and resultant tooth movement. We developed a simulation system of long-term orthodontic tooth movement using the finite element method. Using this system, the tooth movement pattern on the application of the different mechanics can be visualized. This biomechanical study brought us answers to a variety of clinical questions as follows: 1. Why are bowing effects more remarkable with the lingual bracket system ? 2. How effective are power arms in sliding mechanics during en-masse retraction ? 3. Which is better, sliding or loop mechanics ? 4. How is the effect of wire cross-section (horizontal vs. vertical slot) ? 5. How is the effect of compensating curve incorporated into the archwire ? and so on. Finally, the optimal loading condition in the lingual bracket system will be discussed.

Effective combination of orthodontics and myofunctional therapy.
矯正歯科治療とMFTの効果的な連携

[抄録]

口腔機能と歯列形態との間には密接な関係がある。日常生活において、咀嚼・嚥下・発音などの口腔機能が良好に営まれるためには、歯列・咬合の好ましい形態が必要であり、歯列・咬合が良い状態に保たれるためには、良好な口腔機能の維持が不可欠である。
歯列は、舌、口唇、頬などの筋肉から圧力を受けており、口腔機能に問題がある場合、歯列に及ぶ筋圧のバランスが崩れ、不正咬合、矯正歯科治療の後戻り、補綴物の不適合、歯周病の誘発など、様々な歯科的な問題が生じる。
口腔筋機能療法(MFT)は「歯列を取り巻く口腔周囲筋の機能を改善する訓練法」であり、矯正歯科治療とMFTを連携させることにより、形態と機能の両面からのアプローチを行うことができる。
 本講演では、矯正歯科治療とMFTの効果的な連携を行うために必要なポイントを実際の治療例とともに紹介する。

[Abstract]

There is a close relationship between oral functions and dentition. Good oral functions such as chewing, swallowing, and pronunciation require favorable dentition and occlusion morphology, and the maintenance of good oral function is essential for the dentition and occlusion to remain in good condition.
Dentition receives pressure from the tongue, lips, cheeks, and other muscles. When there are problems with oral function, there is an imbalance of muscle pressure over the dentition, resulting in various dental problems such as malocclusion, retroversion of orthodontic treatment, prosthesis mismatch, and induction of periodontal disease.
Oral myofunctional therapy (MFT) is “a training method to improve the function of the perioral muscles surrounding the dentition,” and by linking orthodontic treatment and MFT, both morphological and functional approaches can be taken.
 In this lecture, the points necessary for effective collaboration between orthodontic treatment and MFT will be introduced with actual treatment examples.

Digital Set-Up, Object-Based Outcome Planning & Delivery for Lingual Braces

Dr. Geoffrey Wexler(Australia会長)
Presdient, Australasian Society of Lingual Orthodontists (ASLO)

[Abstract]

Digital Set-Up and Delivery for Lingual Braces removes huge barriers of expensive, laborious manual components and simplifies delivery of treatment.
I will show you a super-capable, simple-to-use, yet very sophisticated digital set-up for lingual braces delivery. This system enables Hidden Lingual Braces but with major cost savings through high efficiency. Such features make lingual braces as easy and fast to set up and deliver as are labial braces, in your every-day orthodontic practice.
Digital Lingual employs the use of Object-Based Outcome Planning.
Object Based Outcome Planning in a digital set-up easily and quickly remediates bracket position errors without the use of bracket placement jigs. It eliminates wire-bending by the doctor. Object Based Outcome Planning enables machine-bending of archwires wires that are made of the most advanced materials, being Super-Elastic NiTi, TMA or CoCr. The outcomes are extremely precise, having “WYSIWYG” accuracy. The system employs simple, inexpensive design & execution. Robust, super-accurate Self-Ligation brackets are my preferred brackets but *any stock bracket may be used*. Elimination of so many barriers to entry makes Lingual Braces completely routine in my every-day practice, so that Lingual braces blend seamlessly into my everyday orthodontic practice. We combine lingual braces with labial braces and clear aligners. We truly can deliver what every adult patient wants – for every malocclusion, Fast Reliable, *Invisible*, in-expensive Teeth Straightening.

Breaking down the barriers to treatment with hybrid appliances

Dr. Asif Chatoo(England)
Fellow in Dental Surgery of the Royal College of Surgeons of England Fellow of the Pierre Fauchard Academy

[Abstract]

Hybrid appliance therapy may be defined as the use different orthodontic appliances in opposing arches to carry out orthodontic treatment.

We now face some new challenges in providing orthodontic treatment.

  • Though we all aim to follow the same high standards of orthodontic treatment, it appears that the “University of Google” and focussed marketing shapes the minds of our patients. Many more patients attend our clinics with pre-conceived ideas on which treatment will be most suitable for them.
  • We need to explain that the provision of orthodontic treatment is not generic. Treatment is patient specific and not ‘one size fits all’.
  • As the technology improves, each type of orthodontic appliance treatment has its own treatment planning platform. The complexity arises when we can not integrate these platforms to provide a cohesive plan.
Working through the myriad of new challenges, how can we provide effective treatment and inform the patients, who now have ‘greater knowledge’, on how successful orthodontic treatment can be achieved?

2021: beyond lingual orthodontics.

Dr. LECOCQ Guillaume(ESLO会長)
President of ESLO

[Abstract]

Every 15-20 years the orthodontic field faces a revolution that creates a new paradigm.
– 1978: the first patents for lingual brackets were delivered: since that date, lingual orthodontics has improved with new brackets and more sophisticated laboratory procedures.
– 1997: the first patents for aligners were delivered and introduced CAD-CAM technology as well as the use of 3D printers.
At that time the laboratory procedures for lingual and aligner therapy were kept secret, exclusive to companies and needed expensive investments. There was also a stimulating competition between companies to develop new features for their appliances.
– Mid-2010’s, 3D technology has become affordable and available on mass market so that doctors have been able to use them for lingual and aligner therapy: in-office design and manufacturing became possible.
Therefore in 2021, the new paradigm is based on understanding and mastering the digital environment : digital setups for lingual or aligner therapy, combination of both techniques with the objectives to improve the results and reduce costs for the patients. That way more patients accept the treatment and doctors get a better control of the appliance because they manage its design.
I will illustrate with cases how I manage the in-office setups and combine advantages of lingual and aligner therapy.

Oral Impacts of Aligners versus Fixed Self-Ligating Lingual Orthodontic Appliances

Dr. Takis Kanarelis(Greece)
Vice President of the Association International des Orthodontistes(2015-2018).

[Abstract]

The aim of this prospective study was to compare a fixed lingual orthodontic appliance with a commonly used aligner system, focusing on oral impacts and speech disturbances, during the first 3 months of orthodontic treatment. Two groups of adults were evaluated: 21 treated with Invisalign® and 26 with In-Ovation L® lingual brackets. Health-related quality of life questionnaires were used to assess the oral impacts, and speech samples were collected for speech evaluation by professionals. The levels of pain and painkiller intake were similar, increasing on the first day, and decreasing at 3 months. Subtle injuries on the lip and cheeks were initially reported in the aligner group. Lingual patients experienced more discomfort in swallowing and opening the mouth, tongue injuries and food residues, even at 3 months. The consonants “s” and “z” were mainly affected in both groups immediately after appliance insertion, but more of- ten in the aligner group. These speech disturbances recovered in the following 3 months. In conclusion, both groups reported disturbances in quality-of-life measures; however, patients wearing lingual appliances experienced more disturbances, which persisted af- ter three months. Speech disturbances were slightly more pronounced in the aligner group and recovered after three months.

Lingual therapy and interdisciplinary dentistry

Dr. Hatto Loidl(Germany)
Former Associate Professor Benjamin Franklin, University Hospital

[Abstract]

There is an ever growing number of different lingual treatment- and transfer systems on the market today.
Most utilise conventional elastics or metal ligatures to fix the archwires to the brackets.
In the following lecture, complex interdisciplinary treatments using the first lingual self-ligating bracket system EVOLUTION® are outlined and examined.
The treatment of patients with complicated malocclusions, that require multiple disciplines of dentistry to work hand in hand, are illustrated in detail. Furthermore, the differences between conventional brackets, self-ligating brackets and the application of the QMS® transfer-system with regards to different wire gauges and different clinical situations are portrayed.

[Abstract]

In the lecture, the author will try to highlight the role of the “Old Classic Biomechanic Principles” that should drive our everyday choices.
It’s a common feeling that sometimes, in our profession, there is a certain “marketing pressure” toward the latest innovations, often boosted by social media…times have truly changed!
Maximum respect and gratitude, of course, for all the researchers and pioneers paving the way and supporting the innovations with strong scientific evidence (always?).
Nothing against high-tech support for a more modern, highly performing, super bombastic orthodontic therapy, of course, but… is “the latest” always the best choice? Was it really widely tested, or maybe it comes right from the fantasy of some good, skilled clinician?
And about “transparencies”…always great and performing? Treating all and all is good?
In the talk, different types of malocclusions, exclusively treated with lingual appliances, will be shown to support my belief, with pretty unusual…and dated… bibliographic references
Let’s do it efficiently… let’s keep it simple…and hidden!

Lingual, Aligners and TADS – The NewAge digital technology and mechanics.

Dr. Pravin Shetty
Managing Trustee & Director , – Vasantdada Patil Dental College & Hospital & Institute of Post-Graduate Studies and Professor

[Abstract]

The newer Digital Esthetic appliance such as Lingual and Aligners has challenged the way we think in treating complex malocclusion cases.

The state of the art Lingualmatrix Cad/cam system is an excellent lingual system for Orthodontists, who wish to have a customised appliance for their patients which can provide them with complete 3 dimensional control, accuracy, good finish, patient comfort , reduced chair side time and minimal appointments.

With the advent of Aligners, plastic polymers , 3D printing technology and virtual tooth movement software, it has enabled us to use Aligners in complex cases and this form of treatment is becoming more popular as it opens up new diamension in current orthodontics ERA.

The presentation shall enlighten on concept , technology features ,and pathbreaking combination of cad/cam lingual appliance ,Aligners with Microimplants for management of complex malocclusion.

今回の講演では、20年間余りの私のリンガル治療について各種不正咬合の症例を通してその治療の特徴と進化についてお話をしたい。フィリオン先生直伝のリンガル治療をベースにして、そこにミニスクリュー・オーソアンカーやMOON先生直伝のMaxillary Skeletal Expander、管原淳二先生のプレートタイプのオーソアンカー等を治療に組み込む事で、上下顎歯列の3次元的コントロールが可能となり、外科矯正なしにもかかわらず、咬合のみならず劇的な顔貌の変化を得ることができたので報告したい。特にリンガル特性を活かした患者固有のトルク処方、エイジングを考慮したIncisor displayにもこだわったリンガル治療にフォーカスを当ててみた。

[Abstract]

I made my debut in lingual orthodontics at the ESLO meeting in Barcelona in 2002, when I presented two cases to become its member. These cases were the second and third cases that I treated using Kurz’s brackets as taught by Dr. Didier Fillion. I went on to learn about mini-screw anchors from Dr. Hi-Moon Kyung and Dr. Choi-Ho Paik, titanium plates from Dr. Junji Sugawara, and Maxillary Skeletal Expander from Dr. Won Moon. Furthermore, the base of my orthodontic treatment was built on the teachings of Dr. Harry Dougherty and Dr. Keith Tanaka at USC, Dr. Terrell Root, and Dr. Richard McLaughlin. This has become the foundation of my current lingual practice enabling me to maximize its clinical effectiveness. I would like to introduce some of the highlights of my lingual orthodontic journey.

[抄録]

矯正治療後に顔貌の変化が改善されることはよく知られている。
見えない矯正装置にはアライナー矯正装置とリンガル矯正装置の2種類が存在するが、顔貌をより大きく変化させられるのがリンガル矯正装置の利点だと考える。
顔貌の変化は側貌の変化とスマイルの変化があるが、側貌の変化は、歯軸傾斜と下顎下縁平面角が大きく影響すると思われる。
ボーンハウジングを実現しながら、咬合だけでなく側貌も改善することを矯正治療の目標としているが、本日は側貌軟組織の評価に用いている独自の分析方法を紹介したい。
美しい笑顔を実現するためのスマイルデザインコンセプトに基づいた矯正治療について、著しい上顎前突症を例に示したい。

[Abstract]

It is well known that facial changes can be improved after orthodontic treatment.
There are two types of invisible orthodontic appliances, aligners and lingual appliances, and I think the advantage of lingual appliances is that they can significantly change facial changes.
There are two types of facial changes: profile changes and smile changes.
For the profile change, the tooth axis and mandibular plane angle have a great influence.
I try to improve not only occlusion but also profile changes while achieving bone housing.
I use my own unique analysis method to evaluate the profile, which I would like to share with you today. I would also like to introduce the orthodontic treatment based on my smile design concept, which I have been working on for over 25 years to achieve a beautiful smile.
Today, I would like to present two cases of significant maxillary protrusion.

上部構造が取り外しできるアンカースクリュー(i-station)は歯の移動範囲を広げた。そのため従来であれば外科矯正治療でしか治せなかった難症例も治療可能になった。しかしながらこのシステムは、複雑な調整を必要とし、使いこなすことが容易ではなかった。
今回新たに開発した着脱式アンカースクリュー(i-stationα)は強固な固定源を有し、複雑な調整を必要とせず、歯の移動に最適な位置に力点を置くことが可能となった。これによりさらに複雑な難症例をより容易に治療することが可能となった。
今回、新たに開発したアンカースクリューを紹介し、その可能性について検討する。

[Abstract]

An anchor screw (i-station) with a removable superstructure has increased the range of tooth movement. Therefore, it is possible to treat difficult cases that could only be cured by surgical orthodontic treatment. However, this system required complicated adjustments and was not easy to master.
The newly developed detachable anchor screw (i-stationα) does not require complicated adjustments, has a strong fixation source, and can place the power point at the optimum position for tooth movement. This has made it possible to treat even more complex and difficult cases more easily.
This time, we will introduce a newly developed anchor screw and examine its possibilities.

審美それとも咬合
Esthetics or Occlusion?

Dr. Isao Matsuno
赤坂まつの矯正歯科 Akasaka Matsuno Orthodontic Office

[抄録]

最近、患者さんの主訴が審美的な傾向が強い気がする。例えば過蓋咬合よりもガミースマイルを、出っ歯よりも顔の前突感に興味があるというものだ。もちろん、審美的改善と咬合の改善はともに治療目的であるが、患者さんの治療の主目的が審美の場合、咬合がとてもよく治っても、少しでも審美的な問題が残っていると、その治療結果には満足せず、自分が満足するためにさらなる治療を望む。その治療のほとんどが外科的なもので、治療経過を説明しても、自分の矯正治療は失敗したのではないかと疑う人もいる。そこで、トラブルを避けるために治療を始める前に外科を含めた治療の可能性を話しておく必要がある。患者さんの要求を満たすためには外科矯正治療が将来増えていくような気がする。

[Abstract]

Recently there is a strong tendency that chief complaint of the orthodontic patients are almost their esthetics problems. For example, they have an interest of the Gummy smile than the deep bite, the facial protrusion than the big overjet.
Of course, both improvement of the occlusion and esthetics are treatment purposes. However, if the patients whose first purpose is esthetics and second is occlusion, finished with excellent occlusion, remains esthetics problem slightly, they cannot be satisfied with the result, they would want the further treatment as they want. This treatment is almost surgical one, and then explain treatment progress, some patient suspects the orthodontic treatment has failed. So, we must explain any possibility including surgery before starting the treatment to avoid the trouble. I feel like it has become more surgery cases to meet such patient’s demands in future.

カムフラージュ治療を行った骨格性下顎前突症例(リンガル矯正のメリット)
Camouflage orthodontic treatment of skeletal Class III (advantages of lingual orthodontics) : Case reports.

Dr. Akiyuki Sakai
エンゼル矯正歯科 Angel Orthodontic Clinic

[抄録]

骨格性下顎前突を伴う症例の治療では、咀嚼能率などの機能的な改善だけではなく審美的な改善のために顎矯正手術を併用することが多い。しかし、外科的侵襲を始めとしたリスクを伴うために、患者の希望によりこのような症例に対して顎矯正手術を適用せず歯性に咬合を改善する治療(カムフラージュ治療)を行うことも少なくない。骨格性下顎前突症は下顎前歯の舌側傾斜を伴うためにリンガル矯正治療では難症例と言われている中、今回、上下顎前歯の被蓋改善を行う際、リンガル矯正特有の歯の動きを生かすことで、矯正治療単独で歯の排列および咬合の確立を行い、良好な治療結果を得ることができた症例を報告する。

[Abstract]

In most cases, orthognathic surgery is the ideal treatment for adults for esthetic improvement as well as functional improvement such as masticatory efficiency, but orthodontic camouflage should be considered as an alternative treatment option, considering the risks of surgery.
However, treatment of skeletal Class III is difficult for lingual orthodontics because it is accompanied by lingual tipping of the mandibular incisors.
This case report shows several cases in which achieved good treatment results by taking advantage of the unique tooth movement of lingual orthodontics.

Orthodontic Treatment System with ZERO TUBE and Lingual Self-Ligating Brackets

Dr. Tetsuya Shimoda
しもだ矯正歯科クリニック Shimoda Orthodontic Clinic

[抄録]

デジタルテクノロジーの普及が進んでいる矯正歯科治療の中で、その恩恵を最も多く受けているのがマウスピース型カスタムメイド矯正治療である。その原形であるTooth positionerは1946年にDr.Keslingにより開発され、約50年後の1997年にCAD/CAMを用い、模型からアライナーを作製するシステムが導入され世界的に急速に広まったことは皆様周知の事実である。
一方、リンガル矯正はアライナー矯正と同じセットアップモデルを元に装置を作製する共通点があり、現在ベンディングされたアーチワイヤー以外の多くがデジタルに刷新されつつある。
今回お話しさせていただくZERO SYSTEMはそのようなリンガルシステムの中でも特にマウスピース型矯正装置との共通項が多く、ZERO SYSTEMの構成要素であるZEROチューブはマウスピース型矯正装置と組み合わせて使う事も可能である。
その要因はZEROチューブがカスタムメイドで有る事と考えているが、今回は筆者が考えるカスタマイズとカスタムメイドの違いなどを定義しながら、
これからのマルチブラケット法の可能性の一端をお見せしたいと思います。

[Abstract]

The custom-made orthodontic treatments with mouthpieces are the most benefited from digital technology which is becoming increasing popular in the Orthodontic treatments.
The original tooth positioner was developed by Dr. Kesling in 1946. It is becoming popular worldwide rapidly after the system to manufacture aligners from models with CAD/CAM was introduced in 1997.
On the other hand, there is a thing in common lingual orthodontic treatments and treatments by aligners.
I will talk about “ZERO SYSTEM” which have a lot of common point of aligner treatment.
The important point is that “ZERO TUBE” is custom-made tube, not customize tube.

リンガル矯正治療とアライナー型矯正装置の併用について
Combination of Lingual Orthodontic Treatment and Aligner Appliance

Dr. Ichiro Aizawa
ソフィア歯列矯正歯科医院 Sophia Orthodontics Clinic

[抄録]

リンガル矯正治療はラビアル矯正治療法と比較して、ブラケット間距離、抵抗中心からのブラケットポジションの位置などの条件から歯の移動様式も異なり、リンガル矯正の場合は治療難易度が高いこともある。
また、リンガル矯正治療におけるディテーリングの段階で、ブラケット脱離が繰り返されると動的治療期間やチェアータイムの延長を余儀なくされる場合もある。
動的治療中においては緊密な咬合が獲得し難い場合もあり、その場合は動的治療後にダイナミックポジショナーを用いて緊密な噛み合わせを獲得する場合もあるが 、装着感に関しては違和感も強く、患者の協力を得られないことも多い。
今回はディテーリングの段階でカスタムメイドアライナー型矯正装置に移行して、ブラケット治療期間の短縮と効率化が図れたのでコンビネーション治療について報告する。

[Abstract]

Compared to labial orthodontic treatment, lingual orthodontic treatment reduces the distance between brackets. Depending on conditions such as the position of the bracket position from the center of resistance, the tooth movement pattern also differs, and in the case of lingual orthodontics, the level of difficulty in treatment may be higher. In addition, in the detailing stage of lingual orthodontic treatment, repeated detachment of brackets may necessitate extension of active treatment period and chair time. In some cases, it is difficult to achieve a close occlusion during active treatment, and in such cases, a dynamic positioner may be used after active treatment to achieve a close occlusion.
However, for whatever the reason, if a dynamic positioner is not comfortable, cooperation is often not obtained. At this time, we will report on the combination treatment which we switched, to a custom-made aligner appliance at the detailing stage. We were able to shorten the bracket treatment period and improve efficiency.

[Abstract]

In lingual orthodontic treatment, it is often more difficult to control the anterior torque at the time of tooth extraction void closure than on the buccal side because the brackets are attached on the lingual and palatal sides. In recent years, the use of orthodontic anchor screws has enabled effective traction and dramatically improved the accuracy of treatment in lingual extraction cases. In this article, we will introduce the use of orthodontic anchor screws useful for lingual orthodontic treatment through case examples of different placement sites and attachments.

Lingual orthodontic method mimicking Le Fort Ⅰ maxillary impaction surgery to improve gummy smile in both the anterior and posterior areas

Dr. Ryoon-Ki Hong(WSLO副会長)
2010-2012President, Korean Association of Lingual Orthodontists (KALO)
2011-2015Vice President, World Society of Lingual Orthodontics (WSLO)

[Abstract]

The reasons for a gummy smile include excessive maxillary vertical growth, over-eruption of the maxillary incisors, incomplete anatomic crown exposure, hyperactivity of the elevator muscles of the upper lip, or a combination of these factors. A gummy smile of skeletal origin requires orthognathic surgery for correction. Dentoalveolar gummy smiles caused by overeruption of the maxillary incisors can be corrected by intruding the extruded maxillary incisors. The dentogingival type of gummy smile is related to abnormal dental eruption or lack of gingival recession and requires lengthening of the anatomic crown. The neuromuscular type of gummy smile is caused by hypercontractibility or excessive muscle contraction and can be improved temporarily by injecting botulinum toxin type A.
With the advent of temporary skeletal anchorage devices (TSADs), the conventional concepts of anchorage control and biomechanics in orthodontics have changed, and many case reports have demonstrated orthodontic correction of gummy smile. Most studies have demonstrated management of gummy smile in the anterior area and facial profile in extraction cases by performing intrusive retraction of the maxillary anterior teeth with labial appliances and TSADs.
Considering the center of resistance and the forces applied, this presentation describes the orthodontic impaction method of the maxillary whole dentition to improve gummy smile in both the anterior and posterior areas and facial profile in a nonextraction case with the use of lingual appliances and one midpalatal TSAD.

Comparison of Various Lingual Orthodontic Brackets

Dr. Hee-Moon Kyung
Dept. of Orthodontics, School of Dentistry Kyungpook National University

[Abstract]

Since the introduction of the modern orthodontic bracket by Dr. Angle, there has been great progress in orthodontic treatment using fixed appliance. Unfortunately, the major components of fixed appliances including brackets, bands, and archwires are attached to the labial and buccal surface of the teeth, which makes conventional orthodontic appliances very unaesthetic, but esthetics was improved in the 1970’s with the introduction of appliances that used a direct bonding system. Orthodontic bands for brackets were discarded, especially in anterior and premolar segments, however, labial appliances still had esthetic limitations.
These days, there has been a marked increase in the number of adults seeking orthodontic treatment, with most of them desiring invisible orthodontic appliances. In order to avoid the unaesthetic nature of labial appliances, Dr. Fujita and Dr. Kurz have developed a lingual bracket appliance in the middle of 1970’s, and many different kinds of lingual brackets were introduced since then.
Dr. Angle first introduced 2 kinds of orthodontic brackets, vertical slot (ribbonwise) and horizontal slot (edgewise) ones, and nowadays, most of orthodontists tend to use edgewise brackets instead of ribbonwise ones. However, so many different kinds of lingual brackets, compare to labial brackets, are used in daily practice.
In this presentation, I am going to share my experience in dealing with different kinds of lingual brackets and to introduce newly developed lingual brackets as well.

Effective incisor intrusion with lingual appliance

Dr. Lim(KALO前会長)
Clinical professor Dept. of Orthodontics,College of Dentistry, Yonsei University

[Abstract]

Since the lingual appliance is located near the center of resistance of the tooth compared to the labial appliance, there is a difference in tooth movement. This difference makes orthodontic treatment itself more difficult and sometimes makes treatment easier and more efficient.
Incisor intrusion is more likely to occur when lingual appliance is used. This is because pure intrusion without tipping is possible because the intrusion force passes near the center of resistance of the tooth. If these characteristics are used, treatment can be performed easily and efficiently in gummy smile correction requiring maxillary anterior intrusion or deepbite treatment where mandibular anterior intrusion is required.

1.Upper incisor intrusion
If there is a mild gummy smile, it can be improved with just the curve of the archwire without using the miniscrew for incisor intrusion.
For moderate or severe gummy smiles, miniscrews are used for incisor intrusion. In this presentation, in addition to the J screw, whose line of action is similar to the J hook headgear, I would like to present an improvement treatment modality using a miniscrew placed in the midpalate area.

2.Lower incisor intrusion
Mandibular anterior intrusion is necessary for deepbite with normal upper incisor exposure. In general, pure intrusion is required because the mandibular incisors are already labially tipping before treatment.
In the case of using the lingual appliance, since the force application point is directly above the center of resistance, it is easy to obtain pure intrusion without using additional archwires or miniscrews. Again, I would like to present its effectiveness through clinical cases.

New update for esthetic anterior alignment

Dr. Sangho Noh(KALO会長)
The President of KALO

[Abstract]

For efficient lingual orthodontic treatment, accurate indirect bonding, proper mechanic application and esthetic finishing process are essential. In many cases of past lingual correction, the lack of understanding or lack of experience of general lingual orthodontic treatment often leads to difficulties in post-orthodontic treatment, difficulty in finishing,
It is generally difficult to confirm the presence of an orthodontic appliance at the beginning of treatment, and it is often difficult to confirm the prescription given to achieve individual treatment goals. In most cases, until the insertion of the rectangular archwire used in the mid-treatment phase, it is possible to assess the presence of an incorrectly attached orthodontic device and prescription. So, we need an understanding of the exact process In lingual orthodontic treatment.
In particular, vertical problems occur during orthodontic treatment accompanied by extraction of premolars. To prevent this during orthodontic treatment, a prescription on the setup model is given.
However, the prescription on the setup model may change due to advances in laboratory techniques, improvements in lingual brackets, advances in mechanics of lingual orthodontic treatment, and accumulation of clinical experience by orthodontists.
For this reason, orthodontists must update their clinical results while gaining clinical experience and apply them to the process of establishing a treatment plan.
In the lecture, based on the updated treatment results based on one’s own clinical experience, these considerations will be discussed in relation to how to arrange the anterior segment according to the individual patient prescription from the production of the setup model and the precautions for archwire bending applied to the patient during the treatment process.

LSW Digital planning in midline recovery

Dr.Gabriela Davicino (Argentina会長)
President of the Argentine Society of lingual Orthodontic SAOL

[Abstract]

It is important to differentiate in facial aesthetics the location of the midline, the existence or not of facial asymmetries, the deviation of the chin, the deviation of the nostrils and the real perception of the midline of the arch, determining the line of the smile, buccal corridor, and its axial inclination.
METHOD:
We offer different alternatives for recovery of the midline, creation of space due to dental agenesis for prosthetic rehabilitation through dental implants.
Recovery of the midline with displacement of the lower arch by means of micro implants in an initial open bite.
CONCLUSION
Through the digital planning and using the necessary mechanics, each tooth movement is exact, obtaining the optimization of the clinical case with high predictable results.
Keyword; aesthetics, asymmetry, digital planning, midline.

Indirect bonding and direct customization with 3D-printed flexible clear resin transfer tray

Dr. Ricardo Gallardo(Chile会長)
Meritorious member of Brazilian Association of Lingual Orthodontics (ABOL)
Director of Avancée Lingual System Chile

[Abstract]

In lingual orthodontics, accurate bracket placement is critical for success of biomechanics. Since morphology of lingual surface is irregular and variable, customization of the bracket base is essential to overcome these difficulties. Indirect bonding is so far, the best method to assure the correct placement and bonding of brackets. With the advent of 3D digital technology, customization is made from a virtual treatment (Set up) before starting the treatment.
Several indirect bonding and customization laboratory procedures have been described in the literature. Most of them consist of modifying the base of brackets either through resin pads or metal casting, both on the malocclusion models. The result is a custom base adapted to the anatomy of the teeth of the working models. Once the brackets are customized, a transfer tray is usually made up of A clear A-silicone (PVS-polyvinyl siloxane). Finally, the brackets are bonded using a fluid or relatively high viscosity resin. However, resin customization on models and the use of a A-silicone trays (PVS) constitute critical procedures that are prone to errors.
To enhance the reliability, precision, and feasibility of indirect bonding and customization, this work describes a new method of brackets customization and construction of the transfer tray by the means of a 3D-printed transfer tray in a clear flexible resin (instead of A-silicone tray). This kind of transfer tray allows a customization made directly on the teeth of the patient during bonding (instead of models).
Literature and clinical examples are presented to show that 3D-printed trays are more accurate than PVS trays and that customization made directly on the teeth of the patient has less procedure errors.

New horizons in digital lingual orthodontics

Dr. James Huang(Taiwan会長)
3rd President of Taiwan Association of Lingual Orthodontists(TALO)
Assistant professor, Ministry of Education, Taiwan

[Abstract]

Lingual orthodontics have evolved in this dgital era and we have enjoyed many benefit from it. Precise indirect bonding is essential for comtemporary lingual orthodontic treatment and it can be divided into two crucial part :model setup and transfer jig fabrication. However,digital model setup has its precision and convenience compared with traditional manual model setup. For instance, we can evaluate arch symmetry,bolton ratio,occlual interference and possible IPR amount very fast. Besides,different treatment plan simulation and technique sensitive bracket positioning decision will be also efficient to carry out easily. Therefore,my new innovative hybrid type of indirect bonding system can be divided into two part as follows:

  1. Digital component: model setup,bracket positioning, individualized arch form template, guiding wire abutment design, then print out the 3D setup model with guiding wire abutment
  2. Manual component: real guiding wire bending with printed out digital guiding wire template, individual transfer jig fabrication with traditional Hiro and Kommon base method. Special design 3D printed out setup model also friendly if you would like to adjust tooth position and doing rebonding

Besides, we can also apply digital technique as a teaching aids in lingual orthodontic education for more cost down and reproducibility.

In summary, digital technique have broaden our working field in lingual orthodontics and give us a whole new world!

[Abstract]

To be more accurate and predictable for my lingual lab work is always my dream, digitalization probably will be the one of solutions. I had tried some digitalized model setup in my office since 2014, however ,we found that there were still some problems existed at that time and more software improvements were required.
In 2018, we started to treat all our lingual patients in digital way and discovered that there are several advantages comparing with the conventional manual setup.
In this presentation, I would like to talk about my experience in digitalization journey and also present some cases for explanation as well.

LOHAS : My favorite things

Dr. Minghsien Lan
Dr. Lan’s lingual orthodontic center, Taipei/Taiwan
Founding President, Taiwan Association of Lingual Orthodontists(TALO)

[Abstract]

LOHAS is the abbreviation of “Lifestyles Of Health And Sustainability“. It means whenever you choose some tools or buy something, be sure to do it in LOHAS way. To our planet, LOHAS also means eco-friendly lifestyles.
Self-ligating lingual orthodontic appliance combining with Tads is my favorite LOHAS way to be the invisible solution of orthodontic treatments.There are several reasons:

  1. It is a kind of fixed appliance so that patient’s compliance is not critical.
  2. It is absolutely invisible and more eco-friendly comparing to aligners.
  3. It can treat almost all kinds of malocclusions, not only simple cases.
  4. It can treat orthodontic cases with quality results, or even better.
  5. It can improve patients’ profiles very well.

In this presentation, I will give some examples to explain in details. Finally, the meaning of LOHAS might be redefined as “Lingual orthodontics Of Hospitality and Simplicity.”

■演題名 リンガル矯正における歯科衛生士の役割

当院では, 初診時にリンガル矯正の特徴として, 審美性に優れている反面, 発音障害や舌の違和感や痛みが生じる可能性等について説明している. 外科的矯正治療や顎関節症, 転医の可能性がある患者には, より詳細な説明が必要である.
動的治療中には, 一般的なエッジワイズ装置に対して, アーチワイヤーの結紮方法の違いや, 抜歯空隙の閉鎖方法など, メカニクスの理解も必要である. 各部位における歯肉形態の違いや, 上下顎歯肉の反応の違いから, 歯ブラシの種類や挿入方向の工夫をしたブラッシング指導を行っている.
装置撤去時の著しい歯肉腫脹に対しては, 後日ボンディング材を撤去することが一般的である.保定中に限局した部位の炎症が継続する場合は, ボンディング剤の取り残しの可能性があるため, 歯肉溝内の確認が必要である.
このように各治療段階において, リンガル矯正の特徴を理解し, 診療に携わることが必要である. 今回はリンガル矯正の治療段階に沿って歯科衛生士の役割をご紹介させていただきます.

■Title:The role of dental hygienists in lingual orthodontics

In our clinic, we explain to our patients the aesthetic benefits, risks of speech disorder and pain of the tongue as a characteristic of lingual orthodontics at the first visit consultation. In addition, we need to explain more details if the patient has a possibility of having orthodontic surgery or TMD, also a possibility of transferring to other clinics in the future.

For active treatments, we must understand the difference in mechanism between lingual and labial orthodontics, such as ligaturing the arch wire and process of space closure of extraction space.We also give tooth-brushing instructions with different types of tooth brushes and describe inserting directions since the difference of gingival morphology of each part and the different reaction of gingiva between upper and lower jaw.

In general, when orthodontic appliances are debonded, if there is severe gingivitis, the bonding agent will be debonded at a later date. If localized inflammations continue during the retention period, we need to check their subgingival condition whether bonding agent is left.

Therefore, I believe that there is a need for dental hygienists to understand the characteristics of lingual orthodontics and participate in treatments. In this presentation, I would like to introduce the role of dental hygienists based on the steps of lingual orthodontics treatments.

そのため、私たち歯科技工士は日々セットアップモデルやポジショニングトレイの品質向上に努めています。
今回の発表では、当院におけるセットアップモデルおよびポジショニングトレーのワークフローを紹介し、その過程で重要な要素を提供することで、矯正歯科技工士のさらなる育成に役立てることを目的としています。
また、過去に作成したセットアップモデルやポジショニングトレーの症例を振り返り、その治療結果をもとに新たな発見をすることも目的の一つです。

■Title:Findings through lingual orthodontic technology until today

In-direct bonding is generally used for lingual bracket orthodontic treatment. In the indirect bonding method, the accuracy of the setup models and positioning trays greatly affects the treatment results. Therefore, we, dental technicians, have been making daily efforts to improve the quality of the setup models and positioning trays.
In this presentation, we will introduce the process of making the setup models and positioning trays, which is an important factor. I hope that this presentation will contribute to the further development of orthodontic technology in the future.
 In addition, I will review some of the cases in which I have fabricated setup models and positioning trays in the past, and discuss what points should be considered in the future based on the treatment results.

演題名 リンガルラボワークとSDGs

現在、わが国では歯科技工士の数が激減しています。歯科技工士学校の入学者数も年々減少しており、閉校する教育機関も増えてきています。また、就職して数年後に離職する人も急増しています。その理由は以下の通りです。1、労働時間が長い、2、休暇や休日が少ない、3、賃金が低い、社会的地位が低い、などである。この問題を解決するためには、「持続可能な開発目標」を策定し、改善を実施することが急務となっています。
2015年に国連総会で採択された「持続可能な開発目標」は、地球上のすべての人々の人権を守り、平等を確保し、差別と貧困をなくし、質の高い教育へのアクセスを確保し、自然環境を重視することを目的としています。また、経済成長や技術革新、仕事のやりがい、健康の享受など、経済・環境・社会の17項目があり、これらは普遍的な考え方の基準として位置づけられている。そこで今回は、私たち歯科技工士、特にリンガルラボワークを例にSDGsの取り組みを考えていきます。多くの人の健康に貢献する歯科技工士の必要性をお伝えしたいと思います。

■Title:The SDGs for Our Lingual Labwork

Currently, the number of dental technicians in Japan is drastically decreasing. The number of students enrolled in dental technician schools is decreasing every year, and the number of educational institutions closing their doors is increasing. In addition, the number of people who leave the industry after several years of employment is rapidly increasing. The reasons for this are 1) long working hours, 2) few vacations and vacations, and 3) low social status in addition to low wages. In order to solve this problem, the “Sustainable Development Goals” must be formulated, improved, and implemented as soon as possible.
The Sustainable Development Goals, adopted by the United Nations General Assembly in 2015, are 17 goals that aim to protect the human rights of all people on the earth, to eliminate discrimination and poverty with equality, to provide access to quality education, and to promote economic growth, technological innovation, job satisfaction, and health with an emphasis on the natural cycle of the environment, economy, environment, and society, This is also regarded as a universal standard of thought. In this report, we would like to discuss the SDGs initiatives using our dental laboratory work as an example, and share the necessity of dental laboratory work to contribute to the health of many people by providing sustainable and high quality orthodontic treatment using digital technology, instead of conventional dental laboratory work that relies on skilled techniques. We would like to share the necessity of dental technology to contribute to the health of many people.

リンガル矯正治療には, セットアップモデルの作成が必須である.
私たち歯科技工士は, 矯正歯科医から指示を受け, 個々の患者さんの治療ゴールを理解したうえで歯の排列を行う. その際, 使用するワイヤーの種類やインプラントアンカー併用の有無, 治療前の歯根の位置等を確かめ, 治療ステップの歯の動きを考慮して適切なオーバーコレクションを組み込むことでチェアサイドでのワイヤーベンドによる調整を極力減らすことができる.
弊社では, 10年以上前から歯科技工のデジタル化に取り組んできた. 当初は海外ソフトウエアに頼らざるをえず, 機能面に不満があったり急な仕様変更やライセンス料の変更や,メーカーの矯正部門撤退など自社ではコントロールできない事態に頭を悩ませてきた. そこで我々はセットアップモデル作成ソフト「AI Orthoエーアイオルソ」を開発し, 運用している. 今回は, 本ソフトを使用したセットアップ作成手順をデジタル独自の利点や, 作業上の注意点をまじえながら紹介する.
また, CBCTの導入が進み, 非抜歯矯正のボーダーケースや歯槽骨の薄いシビアなケースにはCBCTから得た歯根, 歯槽骨のデータをセットアップ作成に用い, ボーンハウジングを確認しながら歯の排列をするようになった. これらは別ソフトでの作成であるが, 近年需要が高まっている分野であるので弊社での取り組みを紹介する.
また, ブラケットポジショニングとインダイレクトコア作成について, アナログ技工とフルデジタルのリンガル矯正システム「Harmony」による技工を比較しながら紹介する.
リンガル矯正技工はデジタル化の過渡期にあります.
私たちは患者さんが快適で, 術者が使いやすく治療に役立つ技工を目指して様々な手法を試してきた. その中で, 現状においてベストな方法を共有し, 更なる改善点を皆様と一緒に考えていきたいと思います。

■Title:Modern lingual orthodontics laboratory

Creating a setup model is essential for lingual orthodontics.
Our technicians receive instructions from the orthodontist, understand the individual patient’s treatment goals and perform the orthodontic alignment.
We then check the type of wire to be used, the presence or absence of implant anchors, the position of the tooth roots before treatment, etc., and incorporate appropriate overcorrections considering the movement of the teeth during the treatment steps to minimize chairside wire bend adjustments.
We have been working on the digitalization of dental technology for the past 10 years.
Initially, we had to rely on foreign software, which presented several challenges for us like dissatisfaction with its functionality, sudden changes in licensing or specifications, termination of the makers’ orthodontic division, etc. Due to this, we developed the “AI Ortho” setup software which we are currently using. In this presentation, we will introduce the setup creation procedure using this software, along with its unique digital advantages and points to keep in mind when working with it.
With the introduction of CBCT, we now use the root and alveolar bone data obtained from CBCT to create setups for border line non-extraction cases as well as severe cases with thin alveolar bone, and we perform alignment while confirming bone housing. Although this is a separate software process, it is an area of increasing demand in recent years, so we would like to introduce our company’s efforts in this area.

We will also compare the analog and fully digital orthodontic techniques of bracket positioning and indirect bonding tray creation using the Harmony lingual orthodontic system.

Lingual orthodontic technology is in the transitional phase of digitalization.
We have been experimenting with various techniques to make it more comfortable for the patient, easier for the operator and more useful for the treatment. We would like to share with you our tried-and-tested best practices, and to discuss further improvements with.

■演題名 私の矯正歯科技工の人生は舌側矯正技工である

 舌側矯正治療は、唇側矯正治療に比べて治療過程が複雑であり、より多くの技術と経験が必要とされます。
これらの工程では、治療結果としての審美性を高め、咬合を安定させ、ドクターがイメージするゴールを達成することが求められます。
これらの難易度が高く、精度の高い治療プロセスのひとつに、私たち技工士が行うセットアップがあり、これも機能的で正確なセットアップが不可欠です。
私は25年以上舌側矯正を学び、矯正歯科の全体(全て)を知り、歯科技工(技工士)の難しさを知りました。
今では、その楽しさもあり、セットアップの症例数は5000例を超えました。
また、ドイツと日本のセットアップを経験することで、システムや治療プロセスの違いをより深く知ることができ、とても良い経験をさせてもらいました(もらっています)。
この貴重な体験を通じて、双方の技工(技術者)をこの大舞台で、私なりの視点で紹介できることを楽しみにしています。
また、先生方の治療の一助になればと思い、後輩技工士(技師)にバトンタッチできるような講演をさせていただければ幸いです。

■Title:My orthodontic technician life is a lingual orthodontic technique.

Lingual (lingual) orthodontic treatment involves more complicated treatment processes than labial orthodontic treatment, and requires more skill and experience. These processes must lead to an esthetic result, a stable occlusion, and a goal as the orthodontist envisions. One of the most difficult and precise processes is the set-up of the prosthesis by the dental technician, which is also essential for the function and accuracy of the set-up.
I have studied lingual orthodontics for more than 25 years and have learned about orthodontics as a whole, and I have learned the difficulties of laboratory work. Now, I am enjoying my work and have done more than 5,000 setups. I also had a great experience to learn the difference of the system and the treatment process between German and Japanese setups. I am looking forward to presenting the technical skills I have gained through this valuable experience on the big stage of this conference.
I also hope that my presentation will help orthodontists in their treatment, and I would be happy if I could pass the baton to the younger generation of dental technicians.
