Abstract

Immediate implant placement into fresh extraction sites has become a relatively routine clinical procedure with a favorable prognosis. However, immediate placement into extraction sockets with lesions has not been extensively documented in humans. Therefore, the purpose of this study was to retrospectively determine the survival rate of implants placed into extraction sockets with visible periapical lesions.

Patient charts of 544 immediately placed implants from Loma Linda University School of Dentistry, Center for Prosthodontics and Implant Dentistry were examined. Eighty-six of the 544 implants had been placed immediately into extraction sockets with periapical lesions and they were included in this study. The radiographs and written treatment records were evaluated to determine the radiographic and clinical status of these 86 implants. Implant length and diameter, local medications used during implant surgery, methods of loading, patient's gender, age and smoking status were documented.

The implant survival data was analyzed by Pierce-wise exponential survival function estimator and log-rank tests for all variables except age, for which the Cox proportional hazards model was used. Survival data with respect to the implant length and diameter were analyzed by the Kaplan-Meier estimator.

Two of 86 implants failed, producing an implant survival rate of 97.7%. None of evaluated variables (implant diameter, implant length, gender, age, local medications used, methods of loading and smoking status) showed any statistical significance (p < 0.05). Based on these observations, it was concluded that immediate implant placement into extraction sockets with periapical lesions can be predictable treatment modality.
