About Our Association's Founding

The Growth of Aligner Orthodontics

Over the past decade, aligner orthodontics has spread throughout Japan, and many patients now have hope for a new option to "straighten their teeth discreetly and comfortably."

Serious Reality

However, behind this, we witness a serious reality. Treatment quality varies significantly between doctors, and many patients suffer from not achieving their expected results.

Social media is flooded with comments like "aligners don't work" and "there are many troubles," leading to misunderstandings about this wonderful treatment method.

Several challenges lie beneath the surface.

In Japan, systematic learning environments and evaluation standards for aligner orthodontics are still developing. Existing academic societies are conducting careful deliberations, and educational systems have room for improvement in connecting with international standards. Due to these circumstances, gaps occasionally emerge between Japan and overseas, including Asian countries.

The Birth of ABAO

To fill these gaps for improvement and complement existing efforts, we established ABAO (Association for the Board of Aligner Orthodontics). Working in collaboration with related academic societies and educational institutions, we provide a neutral, internationally connected learning and evaluation platform.

Our Initiatives

Certification System

To establish scientifically sound and transparent standards of treatment—recognized even by orthodontic specialists—and to present clear, trustworthy criteria for patients when choosing their doctor.

Educational Platform

To build a structured educational system that fosters the next generation and continuously elevates the standard of care.

Social Contribution

To collaborate with leading academic societies, universities, and clinicians across the Asia-Pacific region who have pioneered aligner treatment, and to further advance orthodontic care with a strong international presence.

This is not merely about conferring titles. It is about creating a community where members learn from one another and continuously strive for excellence.

Our Vision

This endeavor may be beyond what existing systems can achieve. Yet that is precisely why it is meaningful for us to take the initiative.

Our mission is to make clear who patients can truly trust with their care and to raise aligner orthodontics in Japan to a world-class standard.

Together with colleagues who share the same commitment, we look forward with confidence to shaping this future.

President: Kosei Kaku

Frequently Asked Questions about ABAO (Q&A)

Answers to frequently asked questions about our association.

Q1. Does ABAO reject the role of universities and academic societies?

A

No. Universities are important institutions responsible for academic research and basic education. ABAO respects this while focusing on "clinical standard setting" and "social safety assurance" that universities find difficult to address. Our roles are complementary, not competitive.

Q2. Why is ABAO needed now?

A

While aligner orthodontics has rapidly spread in Japan, educational systems and clinical standards haven't kept pace. This has led to inadequate evaluations based solely on experience or purchase records, resulting in patient troubles. ABAO was established as a mechanism to address this "social crisis."

Q3. Isn't it unreliable if university professors don't create the certification exams?

A

Exams are created by doctors with extensive clinical experience in aligner treatment, based on internationally recognized textbooks and evidence. ABAO's strength lies in content that is academically grounded yet relevant to actual clinical practice.

Q4. Is ABAO a for-profit business?

A

No. Membership and examination fees are set at the minimum necessary for system operation. Our purpose is not profit-seeking, but delivering peace of mind and trust to society through our certification system.

Q5. Can young doctors and university-affiliated doctors participate?

A

Yes. ABAO welcomes all doctors who want to learn aligner treatment properly, regardless of whether they're orthodontic specialists or general practitioners. We particularly aim to be a new option for young doctors to acquire internationally recognized standards.
