임플란트와 상부보철물의 임상적/실험적 부적합 평가에 관한 문헌고찰

국문 초록 (Abstract)

임플란트와 지대주 간에 허용가능한 적합도를 넘는 부적합을 발견하고 이에 대처하는 것은 중요한 과제이다. 부적합을 임상에서 평가하고 발견하는 방법은 대부분 부적합의 정성적 평가에 치중하고 있으며 술자의 숙련도에 의존하고 있어 정확한 평가방법이라고 하기는 어렵다. 부적합의 정도를 판단하고 원인을 실험적으로 분석하는 방법 중 본 문헌고찰에서는 광탄성 분석법, 유한요소분석법, 스트레인게이지, 미생물 균체분석 등 조건을 모형화하여 분석하는 모형화법과 사진측량, 삼차원 좌표 측정, 현미경분석 및 방사선분석을 통해 부적합의 정도를 정밀하게 측정하는 수치법을 각각 설명하고 그 장단점 및 적용의 한계를 분석하였다. 지금까지 살펴본 실험실 부적합 평가 방법들을 장, 단점 및 정확도와 재현성을 기준으로 표로 정리한 것이 Table 3이다. 어떤 방법도 모든 경우에 적용할 수 있을 정도로 완벽하지는 않으므로 평가하고자 하는 부적합의 특성에 따라 적절한 평가방법을 선택하여 적용하는 것이 필요하다고 사료된다.

다국어 초록 (Multilingual Abstract)

The presence of implant-prosthesis misfits can cause various complications. It is very important to detect misfits to prevent such complications. There are various evaluation methods for misfit assessment including clinical methods and laboratory in vitro methods. The clinical misfit evaluation includes radiographic analysis, visual observation, probing, Sheffield test, evaluation with disclosing materials, and screw resistance test. The laboratory in vitro evaluation method includes indirect modelling evaluation and direct metrological visualization. Of the indirect modelling methods, photoelastic stress analysis, finite element analysis, strain gauge analysis, and microbial colonization analysis were reviewed. Of the direct metrological visualization, microscopic analysis, 3-D photogrammetric analysis, coordinate measuring analysis, and radiographic analysis were reviewed. In this review, the characteristics, advantages and disadvantages of each method were evaluated.
