초록
보철물의 실패는 파절로 인해 다수 발생하게 되지만 파절 발생시 그 원인을 파악하는 것은 어렵다. 보철물의 실패를 예방하고 예후를 예측하기 위해 보철물의 원인을 분석하는 것이 중요하며, 원인을 밝히기 위해 파절면 분석을 시행하게 된다. 파절면 분석은 파절면 뿐 아니라 주위 환경(응력 상황)에 대한 분석이 동반되며, 이를 이용하여 균열 진행, 파절 양상, 파절 원인 등을 파악하게 된다. 이 연구의 목적은 임상적으로 기능 후 파절된 임플란트 고정체의 파절면 분석을 시행하여 파절 기전 및 파절 원인(하중 양상)을 밝히는 것이다. 파절된 임플란트 고정체는 3년간 강릉-원주 대학교에 임플란트 고정체의 파절을 주소로 내원한 환자를 대상으로 수집하였다. 먼저 임상 및 방사선 사진 분석을 하였으며, 시편 세척 과정을 거쳐 주사 전자 현미경을 이용한 파절면 분석을 시행하였다. 임플란트 파절면 분석 시 피로 줄무늬, 벽개 파절 등의 파절 지표를 통해 피로 파절로 인해 파절이 발생되었음을 확인할 수 있었다.
Abstract
The objective of the present study was to perform a fracture analysis on fractured implant fixture after use in vivo and make clear the cause & mechanisms of failure. In case of fatigue fracture, the fractured surface represents fatigue striation. Fatigue striation indicate the progression of the crack front under cyclic loading, are characteristic of stage 2 crack growth. The site of crack initiation and stage 1 crack growth were not easily identified in any of the failure, presumably because of the complex microstructural features of the polycrystalline sample. In case of fractured by overload, dimpled or cleavage surface were observed. Using the interpretation of characteristic markings(ratchet mark, fatigue striation, dimple, cleavage et al) in fracture surfaces, failure events containing the crack origin, crack propagation, material deficiency could be understand.
