TADI was developed from Thai Dental Implant Society which was founded in 1984 by a group of dentists who initiated pioneering implant dentistry in Thailand. The society has evolved in terms of organization and activities, and had a large number of participants. Later, it was registered as Thai Association of Dental Implantology (TADI) in 2009 by Associated Professor Dr.Somchai Sessirisombat who was the first President of the TADI. TADI has expanded its activities to develop and disseminate knowledge and technology of implant dentistry to Thai dentists who are interested and have abilities to serve patients with universal standards. The Association has grown up and its membership has increased steadily. Annual conferences and annual mobility conferences are held to educate members in all regions of the country. To promote Thailand as the center of dental implant in the region, the Association has initiated the Bangkok International Symposium of Implant Dentistry (BIS) in Bangkok, starting in 2010. Although, Thailand had a political crisis during that period, but the BIS2010 was a spectacular success. There were over 500 attendees and followed by BIS2012 with more than 700 attendees. The recent BIS2017 reached more than 900 participants. The Association has expanded its cooperation with the dental implant Association in Asia including Korea, Japan, Taiwan, and the Philippines. The memorandum of understandings (MOUs) were signed with those countries to jointly develop the dental implant group among Asian countries. It also focuses on expanding cooperation to neighboring countries, such as Laos, Burma, Cambodia, Vietnam, to jointly develop academic programs in each country and to provide people in the region with universal standard dental services for oral health and good quality of life.
