2020 - the 9th International Orthodontic Congress

Join us in Yokohama for the 9th International Orthodontic Congress.  Registration is open.

The JOS is ready to bring the world of orthodontics to Japan. Early registration is open until May 31, 2020. Abstract submissions are now open and the deadline for submission has been moved to March 31, 2020.


The Pacifico Yokohama Convention Complex in Yokohama, Japan, will be the site of the 9th International Orthodontic Congress in 2020. The convention complex’s unique shape represents the theme of “Waves, Wind and Sunlight.”

“The Japanese Orthodontic Society believes that holding the 9th IOC in Japan is a great opportunity for all orthodontists to share the research findings and treatment practices that the Japanese orthodontic community has accumulated over the years, while deepening ties between orthodontics and other related domains worldwide so that our area of specialization can further develop as an important pillar of health science,” said Dr. Takashi Ono, chair of the 9th IOC organizing committee. “We also believe that gathering orthodontists and dental care professionals from around the world, who will bring with them their expertise, experience and wisdom, will be of particular significance in expanding and supporting the need for orthodontic care that is rapidly growing throughout the world, particularly in Asia.

“We know that the 9th IOC will provide participants the opportunity to discover and appreciate Japanese culture, tradition and natural beauty. I would like to impress upon you that the Japanese orthodontic and dental community, the Japanese government, the city of Yokohama and other parties concerned are solidly united in our determination to welcome Congress participants and their guests in the best possible manner.”
