The purpose of this study was to evaluate internal conical abutment sinking and fitness according to the loading condition. In this study, Alloden implant fixture and two abutment(conventional, FDI) systems were used. Each abutment was applied 1 time of finger force, 3 times of malleting force, 5 times of 20kg and extra several times to the fixture until the amount of abutment singking showed no change. Then, the length of abutment to fixture which was binding lightly with no pressure state was measured by Vernier caliper. After loading application, the length was remeasured and the amount of sinking was calculated. The implant was buried in unsaturated polyester (Epovia, Cray Valley Inc. Korea) for making a comparison between the change of length and fitness of abutment-fixture connection part. Then All samples were cross-sectioned with high speed precision cut-off(accutom-5, Struers, Denmark). Finally, The result were observed and analyzed using FE-SEM (field emission scanning electron microscopy).

이 연구의 목적은 원추형 내측 연결 임플랜트 시스템에서 하중조건에 따른 지대주의 침하 및 적합도를 평가하는 것이다. 본 연구에서는 내부 원추형 연결방식의 Alloden implant system (Nei Corp. Korea)의 고정체와 2종류(conventional, FDI)의 지대주를 사용하였다. 임상에서 Alloden 임플랜트는 지대주와 고정체 연결시 처음에 손으로 지긋이 눌러 고정시킨 후 mallet을 이용하여 약 3회정도 타격을 가하여 고정한다. 이때 타격시의 정확한 힘을 측정하여 각 실험군에 적용시켰다. 적용 횟수는 손가락으로 누르는 힘을 1회, mallet으로 타격하는 힘을 3회, 저작력으로 가정한 20kg의 힘을 지대주의 침하가 생기지 않을때까지 각각의 표본에 적용하였다. 그 후 각 단계에 대한 지대주의 침하량을 Vernier caliper를 이용하여 측정하였다. 임플랜트는 불포화 폴리에스터(Epovia, Cray Valley Inc. Korea)에 매몰하여 중합시켰고 모든 표본을 절삭한 후 연마하여 주사전자현미경을 통하여 분석, 평가하였다.
