Abstract

Purpose. This study was conducted to evaluate clinical usefulness by evaluating the marginal bone resorption and survival rate of an implant with a taper straight type SLA surface domestically available on the market recently. Materials and methods. 40 implants satisfying the including criteria were observed for one year of 125 implants of 83 adult men and women who had KISPLANT® implanted from August 2016 to December 2019 at the Department of Periodontology, Chonnam National University Dental Hospital. The marginal bone level was measured on periapical radiographs taken initially and 1 year later and we analyzed implant survival and success rates. A t-test was used for the analysis of the association between the marginal bone resorption and the severity of periodontitis, supportive periodontal therapy, the inserted site, the cause of extraction, immediate placement, and systemic disease. Results. After 1 year of loading, the mesial bone resorption was 0.74 ± 1.07 mm, and the distal bone resorption was 0.53 ± 1.04 mm. The marginal bone resorption of 2 mm or more occurred at 3 implants out of 40 implants after 1 year, so the success rate of implant was 92.5% and survival rate was 100%. There was a significant difference in mesial marginal bone resorption according to the inserted site and no significant differences were found between marginal bone resorption and the other factors. Conclusion. As a result of marginal bone resorption, success rate, and survival rate in this study, we found little marginal bone resorption and high survival and success rate. It can be concluded that they represent excellent clinical results.

목적: 이번 연구는 최근 시판되고 있는 국내산 taper straight 타입의 SLA surface를 가진 임플란트의 변연골 흡수도와 생존율을 평가하여 임상적 유용성을 알아보기 위해 시행하였다. 대상 및 방법: 전남대학교 치과병원 치주과에서 2016년 8월부터 2019년 12월까지 KISPLANT®가 식립된 성인남녀 83명의 125개의 임플란트 중 포함 기준을 충족시키는 19명의 40개의 임플란트를 1년 동안의 관찰 대상으로 하였다. 처음과 1년 후의 치근단 방사선 사진에서 변연골 수준을 측정하고, 이를 이용하여 임플란트 생존율과 성공률을 분석하였다. 또한 치주염 심도, SPT, 식립 부위, 치아 발거 이유, 즉시 식립 여부, 전신질환에 따라 변연골 흡수도에 유의한 차이가 있는지를 확인하기 위해 t-test를 수행하였다. 결과: 근심측 변연골 흡수도는 0.74 ± 1.07 mm, 원심측 변연골 흡수도는 0.53 ± 1.04 mm로 나타났다. 1년 동안 40개의 임플란트 중 3개의 임플란트에서 2 mm 이상의 변연골 흡수가 일어나 임플란트 성공률은 92.5%이고 생존율은 100%이었다. t-test를 수행한 결과 근심측 변연골 흡수도와 식립 부위에서 유의한 차이가 있었고 나머지 요인에서는 유의한 차이가 없었다. 결론: 이번 연구에서 변연골 흡수도와 성공률, 생존율을 평가해 본 결과 임플란트 식립 1년 후 높은 생존율과 성공률을 보였고 낮은 변연골 흡수도를 보여 taper straight 타입의 SLA surface를 가진 임플란트는 우수한 임상 결과를 보였다.
