Abstract

The marginal integrity at the composite resin-tooth interface has been analyzed in real time through acoustic emission (AE) monitoring during the polymerization shrinkage of composite resin subjected to the light exposure. It was found that AE signals were generated by the polymerization shrinkage. Most AE hit events showed a blast type signal having the principal frequency band of 100-200kHz. Bad bonding states were indicated by many hit events in the initial curing period of 1 minute with high contraction rate. The quantity of hit events for the human molar dentin specimen was much less than that for the steel ring specimen but more than that for the PMMA ring specimen. The better the bonding state, the less the AE hit events. The AE characteristics were related with the tensile crack propagation occurring in the adhesive region between the composite resin and the ring substrate as well as the compressive behavior of the ring substrate, which could be used for a nondestructive characterization of the marginal disintegrative fracture of the dental restoration.

치아의 와동에 수복된 치과용 복합레진을 광(LED) 조사를 통해 경화 수축시키면서 음향방출(acoustic emission, AE)법을 이용하여 와동 벽면과 복합레진 사이의 계면상태를 실시간 해석하였다. 복합레진의 중합 수축에 의해 AE 신호들이 검출되었는데 계면 접착 상태가 나쁜 경우, 경화 수축률이 큰 초기 1분 동안 많은 AE 사상들이 관측되었으며, 이들 AE는 주파수범위가 주로 100-200kHz인 돌발형이었다. 인간치아 재질의 시편에서 발생된 AE 사상수는 스테인리스 스틸 시편보다 적었으나, PMMA 시편보다는 많았고 접착제의 도포 상태가 양호할수록 검출되는 AE 사상수는 적었다. AE 파라미터의 특성은 복합레진과 링재 사이의 접착부에서 발생하는 인장형 균열전파 및 복합레진의 수축에 따른 링재의 압축거동과 관련되었으며, 음향방출법이 치아 수복물의 접착성에 대한 비파괴 검사법으로써 유효함을 알았다.
