초록
이 연구의 목적은 내측연결 임플랜트 시스템의 고정체-지대주-나사간의 계면 적합도를 알아보기 위한 것이다. 실험에 이용된 임플랜트 시스템은 Certain, Xive, Replace, Ankylos, SSII 이다. 이 시스템의 고정체와 지대주를 제조사의 권장 토크로 조인후 액상의 불포화 폴리에스터 용액에 고정한 후 절단하였다. 모든 표본은 절단, 연마후 주사전자 현미경으로 관찰하였다.내측연결 시스템의 적합도를 관찰한 결과, 각 제조사들 사이에 차이는 있으나 대부분의 내측연결 시스템의 경우엔 고정체와 지대주의 접촉은 긴밀히 접촉하는 경향을 가지고 있음을 알 수 있었다. 그러나 지대주와 나사, 고정체와 나사 간에는 다양한 형태의 틈이 존재하였다. 이러한 틈들이 나사의 불안정, 미생물의 군집, 악취 등에 어떠한 영향을 미칠지는 앞으로 계속적인 연구가 필요할 것으로 사료된다.
Abstract
The purpose of this study was to evaluate mechanical fit of fixture- abutment-screw interface in the internal connection implant systems. In this study, each two randomly selected internal implant fixture- abutment assemblys from Certain, Xive, Replace, Ankylos, SS II. were used. The implants were perpendicularly mounted in liquid unsaturated polyester by use of dental surveyor. Each abutment was connected to the implant with recommended torque value using a torque controller. All samples were cross-sectioned with grinder-polisher unit after embeded in liquid unsaturated polyester, and then fixture-abutment-screw interfaces of all samples by using optical microscope and scanning electron microscope were analyzed. Conclusively, although a little variation in machining accuracy and consistency was noted in the samples, important features of all internal connection systems were the deep, internal fixture-abutment connections which provides intimate contact with the implant walls to resist micromovement, resulting in a strong stable interface.
