Abstract

This article is to review various methods used to investigate internal and marginal adaptation of fixed dental prostheses, and to summarize a merit, worth, and limitation of each method, using some results of previous studies. The methods of measuring internal and marginal gap are divided into two categories in this study; in vivo and in vitro. In vivo methods are clinical evaluations, including exploration, radiography, and impression technique. In vitro methods are laboratory evaluations such as direct view, cross-sectioning, and silicone replica technique using microscope. Measuring by micro computed tomography (CT) or profilometer is also in vitro methods. In recent years, the development of scanning systems is able to analyze 3-dimensional internal and marginal space in detail. As measuring and analyzing technology become more advanced, the ability to thoroughly examine crown adaptation is becoming both simpler and more efficient.

본 논문은 기존에 선행되었던 연구들을 바탕으로 고정성 보철물의 내면 및 변연적합도를 평가하는 여러 가지 방법에 관하여 정리하였으며, 각 방법에 대한 장, 단점에 대해 언급하였다. 보철물의 적합도를 평가하는 방법은 크게 임상적 평가법과 실험실 평가법으로 분류할 수 있다. 임상적 평가법에는 탐침 검사법, 방사선 사진 검사법, 인상채득법이 있으며, 실험실 평가법에는 현미경을 이용하는 변연부 측정법, 절단면 측정법, 실리콘 복제 측정법, 그리고 마이크로 CT나 조면계를 사용하여 측정하는 방법 등이 있다. 최근 스캐닝 기법이 발전하면서 내면 및 변연적합도를 3차원적으로 평가하는 것이 가능해졌으며, 앞으로 측정법 및 분석법의 개발에 따라 보철물의 적합도 평가가 더욱 간편해지고 효과적으로 변화할 것이라 생각된다.
