大会長・理事長挨拶Greet

第４回アジア舌側矯正歯科学術大会の開催にあり、第4回Asian Lingual Orthodontic Meeting（ALOM）を福岡の地で開催できますことを、大変光栄に存じます。本大会の開催にあたり、ご支援・ご協力を賜りました関係各位ならびに国内外からご参加いただいた皆様に、心より御礼申し上げます。 Welcome Message for the 4th Asian Lingual Orthodontic Meeting.

本大会のメインテーマは、「舌側矯正の未来展望：革新と進化の軌跡（The Future of Lingual Orthodontics：A Journey of Innovation and Evolution）」です。近年、矯正歯科の分野ではデジタル化が急速に進展し、これまで術者の経験と技術に頼っていた多くの工程が、スキャン・シミュレーション・製造に至るまで、デジタルデータを基盤とした合理的かつ精緻なシステムへと移行しつつあります。 It is a great honor and privilege to host the 4th Asian Lingual Orthodontic Meeting (ALOM) here in Fukuoka. I would like to express my heartfelt gratitude to all those who have supported the organization of this event, as well as to the participants from both Japan and abroad. The main theme of this meeting is “The Future of Lingual Orthodontics: A Journey of Innovation and Evolution.” In recent years, the field of orthodontics has undergone a rapid digital transformation. Processes that once relied heavily on the clinician’s skill and experience―such as scanning, simulation, and appliance fabrication―are now evolving into highly precise and efficient systems driven by digital data.

さらに、AI（人工知能）や機械学習の進化により、診断支援や治療計画の自動化、治療予測の高度化など、臨床のあらゆる局面に革新がもたらされようとしています。私たちはいま、矯正歯科の新たなパラダイムの入り口に立っていると言っても過言ではありません。 Moreover, the advancement of artificial intelligence (AI) and machine learning is bringing innovation to every aspect of clinical practice―from diagnostic support to treatment planning and outcome prediction. It is no exaggeration to say that we are now standing at the threshold of a new paradigm in orthodontics.

こうした時代の潮流の中で、舌側矯正治療もまた進化を続けてきました。かつては治療の難易度や限界から敬遠されることもあった舌側矯正ですが、装置設計や製作技術の革新、そしてデジタル技術の導入により、その精度や予測可能性は大きく向上しています。とりわけ、個々の患者に最適化されたアプローチを可能とする技術が広がりを見せており、舌側矯正はこれまで以上に、現実的かつ魅力的な治療選択肢となっています。 Amid this wave of change, lingual orthodontics has also made remarkable progress. Once avoided due to its technical challenges and limitations, lingual treatment has significantly improved in terms of precision and predictability thanks to innovations in appliance design, manufacturing technology, and the integration of digital tools. Notably, techniques that allow for individualized approaches tailored to each patient have been gaining ground, making lingual orthodontics a more practical and appealing option than ever before.

さらに今回は、舌側矯正治療に加え、最新のアライナー矯正治療に携わる先生方にもご講演をお願いしております。アライナー矯正もまた、デジタル技術を背景に急速な進化を遂げており、患者の多様なニーズに応える新たな治療法として、矯正歯科の分野において確固たる地位を築いています。さらに近年では、舌側矯正とアライナーを組み合わせたハイブリッド治療の可能性も示されており、これからの矯正歯科治療の重要な方向性の一つとして注目されています。 For this meeting, we have also invited leading experts in the field of clear aligner therapy, which has advanced rapidly alongside digital technology. Aligner orthodontics has established itself as a viable treatment modality that addresses diverse patient needs. In recent years, hybrid treatments that combine lingual appliances with aligners have also emerged, representing a promising direction for the future of orthodontic care.

ALOMは、アジアにおける舌側矯正の知見と技術を共有し、その進展と多様性を互いに学び合う場として生まれましたが、本会ではその枠をさらに広げ、未来の矯正歯科全体の展望について議論を深める機会としたいと考えております。各国の臨床家・研究者による貴重な発表を通じて、異なる視点を学び合い、新たな連携や発想が生まれることを期待しております。 Originally conceived as a platform for sharing knowledge and techniques in lingual orthodontics across Asia, ALOM now aims to broaden its scope by fostering deeper discussions on the future of orthodontics as a whole. Through valuable presentations by clinicians and researchers from various countries, we hope this meeting will inspire new perspectives, collaborations, and innovative ideas.

また今回は特別講演として、実業家・著作家として多方面でご活躍されている堀江貴文氏をお迎えいたします。堀江氏には、「未来を見据えた歯科医療の可能性」をテーマに、歯科界が直面する変革とその先にあるビジョンについてご講演いただく予定です。異業種からの視点が、私たち矯正歯科医に新たな気づきと刺激を与えてくれるものと確信しております。 We are also honored to welcome Mr. Takafumi Horie―an entrepreneur and author with wide-ranging achievements―as a special guest speaker. He will address the theme “The Future Potential of Dental Medicine,” offering his insights into the transformations facing the dental profession and its evolving vision. We believe that his perspective from outside the field will provide us with fresh inspiration and thought-provoking challenges.

開催地である福岡は、古来よりアジアの玄関口として、文化・経済・人の交流を担ってきた都市です。その歴史と精神のもと、今大会が新たな交流と連携を生み出し、参加者の皆様にとって実りある時間となることを心より願っております。 Fukuoka, the host city, has long served as a gateway to Asia―connecting cultures, economies, and people. In this spirit, we sincerely hope that this meeting will foster new connections and collaborations, and that it will be a fruitful and enriching experience for all participants.

ジャズ、、、
舌側矯正はジャズに似ている。 Jazz…
Lingual orthodontics is similar to jazz.

おそらく、ジャズを聴いている人は少ない。売り上げだけを見れば、世界で最も売れているアーティスト一人分の売り上げと同じくらいだろう。舌側矯正のシェアも同様である。 If you look at the sales alone, it’s probably about the same as the earnings of one of the world’s best-selling artists.

しかしながらジャズを奏でる人は格好いい。なぜか、それは自由だからである。いい音といい音を掛け合わせるために自由に奏でるのがジャズである。舌側矯正も自由である。いい結果を出すためにワイヤーの向きを変えてみたり、インダイレクト法のコアも様々である。 But people who play jazz are cool.

自由に行えるということは、一見してラフな感じもするが、即興演奏やアレンジの裏には、音楽理論や高度な技術が隠されている。それにより、聴く側にはそれが自然に響く。舌側矯正も同様で自由に行うためには、矯正医としてより高度な知識とスキルが必要となる。そのため、舌側矯正が上手いひとは、矯正治療全般が上手いと言われることが多い。 Winning with freedom may seem rough at first glance, but behind the improvisations and performance arrangements, music theory and advanced techniques are hidden.

豊富な知識と経験に裏付けられた自由。それゆえに、格好いいのである。若い矯正医には、この”知識と経験に裏付けられた自由”を目指して欲しいと切に願う。 Freedom backed by abundant knowledge and experience. That’s why it’s cool. I hope that young orthodontists aim for this “freedom backed by knowledge and experience.”

今回アジア舌側矯正歯科学術会議(ALOM)の大きなテーマは”デジタル”である。デジタルも同様に自由な発想をもって従来のシステムと奏でることで、予想以上の効果が得られることもある。しかしながら、現在のデジタル化はそこまでの利益を我々にもたらしてはいない。使用する側の “手段の目的化” が進んでいるからであろう。 The main theme of the current Asian Academy of Lingual Orthodontics (ALOM) is “digital.” Similarly, by playing digital with traditional systems with a free idea, it can sometimes produce results beyond expectations.

本来、デジタル化はより良い治療をする、よりシンプルに良い結果を出す事が目的であるであるが、”デジタルを使用する事”、”デジタルで行う事”が目的となっていないであろうか。本来手段であるはずのデジタル化が、デジタルで行うという目的になってしまっているのではないだろうか。 Originally, the purpose of digitalization is to provide better treatment and to produce better results more simply, but I wonder if the purpose is not to “use digital” or “do it digitally.”

この会が、デジタル化への警笛となり、さらには発達した治療への特異点となる事を願う。 I hope that this meeting will serve as a warning against digitalization and become a singular point for further advanced treatment.

Don’t just be an Aligner, Be an Orthodontist.
並べるだけの人になるな、矯正医たれ。 Don’t just be an aligner, become an orthodontist.

Distinguished members of KALO and JLOA, and esteemed lingual orthodontic specialists from across Asia and around the world who have graciously joined us today:

It is a great honor and a sincere pleasure to welcome all of you to this special event.

In the past few years, the rapid adoption and advancement of clear aligner systems have significantly reshaped the landscape of aesthetic orthodontics. We are all keenly aware of the concern that, amid these changes, the role of lingual orthodontics appears to be diminishing. Indeed, the complex biomechanics and high level of clinical expertise required for lingual treatment have long been seen as obstacles, making its adoption more difficult for many practitioners.

However, lingual orthodontics has recently encountered an unprecedented opportunity to leap forward, thanks to its integration with powerful digital technologies such as intraoral scanning, virtual setups, and 3D printing. The emergence of AI-assisted treatment planning, precision 3D-printed custom brackets, and highly accurate indirect bonding guides are transforming lingual orthodontics into a faster, more precise, and more predictable form of treatment than ever before.

In particular, the digital setup models that we have long used in lingual orthodontics are now being shared with clear aligner therapy as well. This convergence suggests that the relationship between lingual and clear aligner treatment need not be one of competition. Instead, their respective strengths and limitations can complement one another, offering the possibility of more effective and efficient hybrid treatment strategies.

This 4th Asian Lingual Orthodontic Meeting will serve as a platform to share the digital technologies and innovative ideas that can help bring this possibility into clinical reality. I hope this academic gathering becomes a meaningful opportunity for us to explore the path forward and to shape a new future for lingual orthodontics together.

With heartfelt gratitude, I look forward to your passionate participation and the inspiration you will bring to this event.

As the current President of the Taiwan Association of Lingual Orthodontists (TALO), it is my great honor to extend my warmest greetings to all of you. I am truly grateful for the trust you have placed in me, and I look forward to working together to advance both the clinical and academic development of lingual orthodontics.

Since its founding in 2015, TALO has been committed to building a platform that fosters clinical excellence, academic exchange, and professional collaboration. Over the years, we have maintained strong and friendly relationships with JLOA and KALO, supporting one another and growing together as a regional community.

Today, we find ourselves at a critical crossroads. With the rapid rise of aligner therapy, attention has gradually shifted away from lingual orthodontics, posing new challenges to our field. Yet despite these shifting trends, we must continue to believe in and advocate for the irreplaceable and unique value that lingual treatment offers.

Lingual orthodontics not only provides true invisibility, but also carries significant environmental benefits—minimizing contact with plastic particles and reducing overall waste. This treatment approach reflects a deeper commitment to both medical quality and sustainable development.

What inspires me most is the enduring passion of the global lingual orthodontic community. From pioneers and specialists to educators, so many continue to dedicate themselves to lifelong learning and international collaboration. I truly believe that the 4th Asian Lingual Orthodontic Meeting will serve not only as a meaningful academic exchange, but also as a source of inspiration and solidarity for all of us who are passionate about this beautiful field.

Lingual orthodontics is more than just a technique—it is a symbol of our shared dedication to excellence, precision, and thoughtful patient care. Let us continue this journey with courage and conviction, and keep contributing to the field we so deeply believe in.
