摘要
BackgroundLong-term studies of 10 years are important milestones to get a better understanding of potential factors causing implant failures or complications. PurposeThe present study investigated the long-term outcomes of titanium dental implants with a rough, microporous surface (titanium plasma sprayed [TPS]) and the associated biologic and technical complications in partially edentulous patients with fixed dental prostheses over a 20-year follow-up period. Materials and MethodsSixty-seven patients, who received 95 implants in the 1980s, were examined with well-established clinical and radiographic parameters. Based on these findings, each implant was classified as either successful, surviving, or failed. ResultsTen implants in nine patients were lost during the observation period, resulting in an implant survival rate of 89.5%. Radiographically, 92% of the implants exhibited crestal bone loss below 1mm between the 1- and 20-year follow-up examinations. Only 8% yielded peri-implant bone loss of >1mm and none exhibited severe bone loss of more than 1.8mm. During the observation period, 19 implants (20%) experienced a biologic complication with suppuration. Of these 19 implants, 13 implants (13.7%) had been treated and were successfully maintained over the 20-year follow-up period. Therefore, the 20-year implant success rate was 75.8 or 89.5% depending on the different success criteria. Technical complications were observed in 32%. ConclusionThe present study is the first to report satisfactory success rates after 20 years of function of dental implants with a TPS surface in partially edentulous patients.
