The purpose of this study was to analyze the risk factors for 5-year loaded tapered implants with SLA surface. From June 2003 to February 2005, 65 patients (a total of 139 Implantium® (Dentium, Suwon, Korea) implants) were enrolled and cumulative survival was calculated based on Kaplan-Meier method. To confirm prognosis factors, Cox proportional hazard model was established. Among the 139 implants, 6 implants failed and the 5-year cumulative survival rate was 95.41%. Failed implants were 3 for osseointegration failure, 1 for malposition, and 2 for peri-implantitis and progressive bone loss respectively. There were no meaningful differences in the cumulative survival rates between maxilla and mandible, maxillary posterior area and other regions, and maxillary posterior area with and without sinus bone graft (p>0.05). Irrespective of graft location, delayed loaded cases due to improper primary stability from simultaneous bone graft increased the failure rate. © 2012 Asian Association of Oral and Maxillofacial Surgeons.
