초록

골유착성 임플란트가 소개된 이후로 부분 및 무치악 부위에서 사용되어 높은 성공률과 함께 예지성 있는 결과를 보여주는 치료방법으로 인정받고 있다. 그러나 국내에서 개발된 임플란트에 대해서는 임상적이고 객관적인 연구 자료가 불충분하다. 본 연구에서는 31명의 환자에게서 임플란트 경부에 미세나사를 지닌 임플란트 식립 후 평균 21개월의 기간 동안 임플란트의 생존율에 관한 조사를 시행하였고 부하가 가해지는 시점을 기준으로 12개월 간 변연골의 변화를 파노라마사진을 이용하여 측정 관찰하여 다음의 결과를 도출하였다. 총 96개의 임플란트에서 3개의 임플란트가 실패하여 96.9%의 생존율을 보였다. 50대 환자에서 85.7%로 가장 작은 생존율을 보였으며 성별 및 연령에 따른 생존율 및 변연골 흡수량에 대한 통계적 유의성은 존재하지 않았다. 상악에서는 95.7% 하악에서는 100%의 생존율을 보였다. 골이식 여부, 보철물의 종류, 매식체의 길이 및 직경에 따른 생존율의 차이는 통계적으로 유의한 차이를 보이지 않았다. 기능 부하 후 임플란트 변연골 흡수량은 단일 금관 보철물이 연결 고정 보철물에 비해 증가된 양상을 보였으나 임플란트의 직경, 길이, 골이식의 유무, 식립위치에 의해서는 통계적으로 유의한 차이를 보이지 않았다. 이 연구를 통해 경부에 미세나사를 지닌 임플란트 식립 후에 임플란트 변연골 흡수량은 비교적 적게 일어났으며 또한 안정적으로 유지되는 것이 관찰될 수 있었고 이에 따른 장기적인 추적관찰이 필요할 것으로 사료된다.

Since the introduction of the concept of osseointegration in dental implants, high long-term success rates have been achieved and accepted as viable option for the treatment of fully and partially edentulous patients. Although the use of domestic implants have increased dramatically, there are few studies on domestic implants with clinical and objective long-term data. 96 endosseous implants placed in 31 patients at Wonkwang University Sanbon Dental Hospital were examined to determine the effect of various factors on implant survival rate and marginal bone loss, through clinical and radiographic results. The design of endosseous implant used to this study is straight with the microthread.(GS II RBM Fixture) 1. 3 fixtures were lost, resulting in 96.9% cumulative survival rate. 2. Survival rate in fifties was significantly lower (93.6%) and no significant difference in marginal bone loss was found according to gender. 3. Survival rates were 95.6% in the maxillary molar area and 97.3% in the mandible molar area. 4. No significant difference in survival rate was found according to presence of bone grafts, type of prostheses, implant position, and length and diameter of implant. 5. A factor influencing marginal bone loss was presence of type of prostheses, while facters such a length, diameter of fixture and bone grafts had no statistically significant effect on crestal bone loss. This study indicates the amount of marginal bone loss around implant has maintained a relative stable during follow-up periods.
