A questionnaire survey was conducted to determine the information required by patients prior to providing informed consent for dental implant surgery. Questionnaires were distributed to 1,585 patients who visited the Tokyo Medical and Dental University Hospital for oral implants between January 2012 and December 2012, of which 1,159 (73%) valid questionnaires were collected. The results showed that preservation of an adjacent tooth was the reason that 32% of participants chose implant therapy. Over 70% of participants indicated that their main concerns regarding implant therapy were aftereffects of surgery, the number of years the implants would be in place, and treatment cost. Regarding knowledge about implant therapy, patients' most frequent reply was“ I do not know” when asked about postoperative pain, peri-implantitis, the importance of implant maintenance, and the relationship between general health and implant therapy. Fifty-nine percent of the patients recognized smoking as a risk factor for periodontal disease, of which 23% recognized smoking as a risk factor for implant therapy. Sixty-one percent of patients replied“ more than 20 years” when asked about the number of years that they believed the implants would be in place. This research identified the information required by patients in order to provide informed consent. Comprehensive information is required before informed consent is sought, as the majority of patients did not possess sufficient knowledge regarding implant therapy.
