This study was performed to evaluate the systemic risk factors related to implant by analyzing the post-op complications, the rate of dental implant failure, and peri-implant crestal bone resorption. A total of 1,292 implants in 397 patients were included. We analyzed data regarding gender, age, implant location, systemic disease, post-op complications and peri implant crestal bone resorption based on periapical radiographs and dental charts. Patients with a systemic disease showed a higher incidence of post-op complications than the normal patients group. Especially, hypertension, cerebrovascular disease and psychiatric disease were significantly related with post-op complications. The rate of dental implant failure of the nor mal group was 7.02%, while in the systemic disease group, implant failure occurred in 7.29% of the implants. Cardiovascular disease was statistically associated with implant failure. There was no significant difference between the normal group and the systemic disease group. Between the group of normal patients and the group of systemic diseased patients, there was no significant difference in crestal bone resorption at 1 year, 2 years, and 3 years post-op. Systemic dis ease and peri-implant crestal bone resorption was independent. The implant failure rate of male patients was 8.63% while 5.4% of female patients experienced implant failure. The maxilla failure rate was 11.23% but only 2.64% at the mandible. Implant locations were statistically related with implant failure rate. The systemic disease group showed higher rates of post-op complications than the normal group.
