초록

가시광선 중합형의 치아수복용 고분자 복합체(polymeric dental restorative composites, PDRC)에 있어서 여러 종류의 3급 아민계 광증감제가 PDRC의 치과적 물성에 미치는 영향을 기계적 물성과 심미적 특성을 분석한 후 고찰하였다. PDRC 제조에 사용한 barium silicate 필러는 아크릴계 resin matrix와의 혼화성 증가를 위해 표면을 소수성으로 처리하여 사용하였다. 광중합에 필요한 광개시제로는 resin matrix를 기준으로 camphorquinone을 0.5 wt%로 하여 사용하였다. 그 결과, 제조된 PDRC의 기계적 물성과 심미적 특성은 사용한 광증감제의 함량보다는 화학적 구조에의 의존성이 더 큼을 알 수 있었다.

The aim of this study was to evaluate the effect of tertiary amine photo-accelerator on the dental properties of visible light-activated, polymeric, dental restorative composites (PDRC) through the measurement of mechanical and esthetic properties. The surface of barium silicate was hydrophobically treated to improve the interfacial behavior with the acrylic resin matrix. Camphorquinone was adopted as a photo-initiator with 0.5 wt% based on the resin matrix. It was discovered that the dental properties of PDRC were primarily dependent on the chemical structure rather than the added content of photo-accelerator.
