therapeutic options. Many studies regarding implant survival rates have been published. However, there have been few long-term studies on implant survival rate in Koreans. Therefore, the aim of this study was to examine implant survival rate for 8 years as well as identify potential risk factors for failure. Materials and Methods: The present study included 535 implants in 332 patients at the Department of Periodontology of Wonkwang Dental Hospital. By means of a chart review, 1) implant site, 2) age and sex of patients, 3) diameter and length of placed implant, 4) advanced technique at recipient site, 5) periodontal treatments before implant therapy, and 6) systemic diseases such as diabetes mellitus, hypertension, or osteoporosis were recorded. The effects of evaluated variables on implant failure were analyzed using chi-square test. Statistical significance was accepted at p<0.05. Results: The present study showed an implant survival rate of 97.76%. Overall, 12 of 535 (2.24%) implants were explanted. Two explanted implants were in the maxillary anterior area, five were in the maxillary posterior area, and five were in the mandibular posterior area. The average time from placement to explantation was 11.92±15.30 months. None of the investigated factors was significantly associated with implant failure (p>0.05). Conclusion: Survival rate in this study was 97.76%. Despite the lack of significant association between implant failure and associated factors, there are potential risk factors. Cautious diagnosis and treatment planning are needed.
