The Korean Association for Temporomandibular Joint traces its origins to 1994, when the Korean Temporomandibular Joint Research Institute was established.
According to earlier English-language records, the association was formally founded on April 15, 1995, at Inchon Memorial Hall of Korea University, with Professors Kwon Jong-jin, Chung Hoon, and Han Jung-suk among the key founding figures.
The association was approved by the Ministry of Health and Welfare as an incorporated association on December 26, 2000, and has since developed into an important academic and professional body dedicated to the research, education, and clinical advancement of temporomandibular joint disorders in Korea.
Over the years, it has contributed through academic meetings, continuing education, specialist-oriented clinical training, publications, patient and public education, and international exchange.
Its recent activities include the 30th anniversary academic conference in 2024, spring and autumn academic programs in 2025, hands-on educational seminars in 2026, and public outreach initiatives such as mastication-habit campaigns and forums.
The association also continues to play an active role in regional and international collaboration, including academic exchange within the Asian TMJ community and renewed cooperation with the Japanese TMJ society.

The Chinese Society of Occlusion was established in 1989 under the leadership of Professor Wang Hui-yun of the Fourth Military Medical University.
In 1997, the Chinese Society of Temporomandibular Disorders was founded, with Professor Ma Xuchen of Peking University School of Stomatology serving as its chair.
In 2002, the two societies merged to form the Chinese Society of TMD and Occlusion, with Professor Ma Xuchen as founding chair and Professor Zhang Zhen-kang as honorary chair.
From the beginning, the society brought together specialists from oral and maxillofacial surgery, prosthodontics, orthodontics, oral radiology, oral physiology, and related disciplines, reflecting the multidisciplinary character of this field.
It has since developed within the Chinese Stomatological Association as the Committee of TMD and Occlusion.
As of the seventh committee elected in October 2023, it includes 174 members and 53 standing committee members, with Professor Zhu Songsong serving as chair.
In recent years, the committee has expanded its activities through national academic meetings, continuing education programs, and expert consensus development.
The society had reached its 21st national symposium by 2024, and its 22nd national symposium was scheduled for 2025, demonstrating its continuing growth and leadership in the field of TMD and occlusion in China.

The Japanese Society for the Temporomandibular Joint (JSTMJ) traces its origins to 1980, when the Society for the Study of TMJ began its academic activities.
Earlier accounts credit Professors Toru Oka, Jun Takasu, Shojiro Takahashi, and Takatoki Ono among the founding figures, while the society’s official history records that the first scientific meeting was held at Nagoya University Hospital in June 1980 under the leadership of Dr.Tohru Oka.
After annual meetings continued throughout the 1980s, the organization was formally established in Nagoya in July 1988 as the Japanese Society for the Temporomandibular Joint, and it later became a general incorporated association in 2008.
Today, JSTMJ continues to play a leading role in research, clinical practice, education, and professional training related to temporomandibular joint disorders and associated fields.
The society holds an annual congress every year, has expanded its scientific lecture program to multiple meetings annually, publishes the Journal of the Japanese Society for the Temporomandibular Joint, and supports a comprehensive certification system for specialists, instructors, certified clinicians, training institutions, and dental hygienists.
It also contributes to clinical standardization through updated guidelines and publications and remains active in regional and international exchange, including collaboration within the Asian TMJ community and ongoing academic ties with Korea.
