초록

최근 무치악 부위를 대신하여 광범위하게 식립되고 있는 치과용 임플란트는 높은 임상 성공률을 보이고 있으나 실패 가능성은 늘 존재하며 이는 예기치 않은 경우가 많다. 임플란트의 실패과 관련하여 여러 가지 요인들이 거론되고 있으나, 아직 논란의 여지가 있다. 본연구에서는 서울 보훈병원에서 2005-2006년에 하악 구치부위에 임플란트를 식립한 212명의 환자, 총 358개의 임플란트를 대상으로 환자의 연령, 임플란트 식립 부위, 시스템, 직경과 길이, 골이식 유무에 따른 생존율을 비교하였다. 각 요소에 따른 생존율을 SPSS chi-square test를 이용한 multi-variable analysis를 시행하여 관련성을 검증하였다. 연구 결과 3년간 98.3% 의 누적 생존율을 보였으며, 조사한 요인 중 임플란트 직경만이 임플란트 생존율과 관련성이 있는 것으로 나타났다. 이는 넓은 직경의 임플란트가 주로 대체(rescue) 임플란트 혹은 골질이 좋지 않은 부위에 사용되는 경우가 많은 것이 원인으로 작용한 것으로 사료된다. 향후 임플란트의 성공과 관련하여 명확한 지표를 제공할 수 있는 지속적인 연구가 필요할 것이다.

Abstract

Recently, dental implants extensively inserted on edentulous area show highly clinical success rate. However, clinicians cannot exclude the possibility of failure and it often unexpectively occures. Many possible factors associated with failure of dental implants have been reported but controversy exists over the extent to them. In this study, we collected 212 patients who had been inserted 358 dental implants on mandibular premolar and molar area from 2005 to 2006. The survival rate of fixtures was recorded according to age of patients, implantation site, implant system, diameter and length of fixtures. Multi-variable analysis using SPSS chi-square test was operated to verify relation of each factors and survival rates. Accumulative survival rate was 98.3% for 3 years. Only diameter of fixtures was related to the implant survival rate. This may be thought that wider fixtures had been chosen to rescue implants or used in sites of poor bone quality. Further continuous study will be needed for direct guidance associated with survival rate of implants.
