It will be the first time in the federation’s 86-year history that the congress will be held in Asia.
Around 6,000 delegates are expected to attend the event, which takes place every five years.
The Yokohama Convention & Visitors Bureau worked closely with the Japanese Orthodontic Society (JOS) to beat seven other destinations to host the congress.
Executive Committee members recognised the capability of PACIFICO Yokohama, the city’s all-in-one venue, as well as the region’s public safety record and support from local government.
Dr. Moriyama of the JOS, who will take on the role of Chairman of the Organising Committee for the 2020 Congress, said: "We 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, but particularly in Asia."
The last International Orthodontic Congress took place in Sydney in 2010 and attracted 2,200 delegates.
Future medical congresses booked with Yokohama include the Congress of the World Union of Wound Healing Societies (2012), World Congress of the Human Proteome Organization (2013) and the Congress of the World Federation of Occupational Therapists.
