ABSTRACT
The present study was aimed to evaluate the findings of Laser-Lok® (LL) dental implants in various clinical indications, inserted in a private practice setting and monitored for more than 20 years, statistically analyzing the associate failure risk factors.
MATERIALS AND METHODS: Data of patients receiving LL dental implants and whose prosthetic reconstruction in the period 2000-2005 in a private practice clinic were retrospectively evaluated and statistically analyzed. Kaplan-Meier survival curve was used to determine the cumulative survival rate (CSR), and a binary generalized estimating equation model (GEE) was used to evaluate the influence of various factors on CSR.
RESULTS: Between January of 2000 and December of 2005, 730 LL implants were placed in 312 patients for a variety of clinical indications. Following implant placement, patients were checked at follow-up visits every six months for an average of 16.8 years. The Kaplan-Meier cumulative survival rate (CSR) at 5, 10, 15, and 20 years were 98.2%, 97.1%, 95.8%, and 95.3% respectively. Seven factors were identified associated with late implant failures: male, smoking, maxillary posterior area, immediate dental implant placement and immediate loading protocol, (D4) bone quality, and ≥ 35 Ncm insertion torque.
CONCLUSION: LL dental implants monitored for up to 20 years showed high CSRs and low rates of marginal bone loss.
