Abstract

Objective. Objective: To determine the 2-year implant survival rate in the NSU postgraduate periodontology clinic and assess the effect of various patient and surgical factors on implant survival. Background. Background: In the US the number of dental implants placed has steadily increased and is projected to continue at 12% annually. The survival rates for implants are high, the most recent systematic review suggesting 97.7%. Despite the predictability of dental implants, a small but significant subset of patients experience implant failure. Identifying patients most at risk of failure and surgical factors affecting survival is essential to reducing failures. Methods. Methods: Electronic records for all implant surgeries from January 3, 2008 to December 31, 2010 were reviewed. Implants with a 2-year follow-up were included and classified as “survived” if they were restored and in function at the end of the 2-year period. Factors considered were: patients' age, gender, smoking status, and surgical factors: immediate placement, location, site grafting or sinus augmentation, submerged cover screw and non-submerged healing abutment, immediate temporization and loading, preoperative antibiotic use, and academic year of resident placing the implants. Results. Results: 52 out of 1,282 implants failed, a success rate of 95.9%. Males were 1.7 times more likely to have failures. Implants in smokers were four times as likely to fail compared to non-smokers. Patients not given pre-operative antibiotics were 2.3 times more likely to have failures than patients given pre-operative antibiotics. Those with sinus lifts produced a significantly greater number of failures versus no sinus lifts. Conclusion. Conclusions: The NSU postgraduate periodontal clinic implant survival rate was comparable to published standards. Statistically significant factors affecting implant survival included gender, smoking, preoperative antibiotics, and sinus lifts. Grants. No.
