수산화인회석으로 혼성화시킨 바륨실리케이트가 충진된 고분자 복합체의 치과적 물성

초록
치아 수복용 충전제로서 인체 뼈의 주성분인 수산화인회석(hydroxyapatite)이 혼성화된 바륨실리케이트(barium silicate, BaSi)를 사용하여 제조한 고분자 복합체의 치과적 물성을 분석하였다. 복합체 제조에 사용된 아크릴계 기재는 가시광선을 사용하여 경화시켰다. 실험 결과, 혼성화된 충전제 내에서의 BaSi 함량이 증가할수록 복합체의 기계적 강도는 일정하게 증가하였으며 치의학에서 규정한 값들을 상회하여 치아 수복재료로 충분한 값임을 확인할 수 있었다. 그러나 충전제 내에서의 BaSi 함량 증가에 따른 복합체의 내마모도는 약간 감소하였다. 한편, 복합체의 중합깊이는 충전제의 구성비에 관계없이 6∼9 mm 정도로서 일반적 치과용 수복재료로 충분한 값들임을 확인하였으며 중합전환율과 중합수축률은 충전제 구성비에의 직접적 의존 경향성은 거의 없음을 확인할 수 있었다.
Dental properties of polymer composite loaded with hybrid filler of barium silicate (BaSi) and hydroxyapatite, which is a principal component of human bone material, were investigated. A visible light system was utilized to activate the acrylic resin matrix of the composite. Based on the experimental results, it was found that mechanical strength of the composite was consistently increased with an increase of BaSi content in the hybrid filler. And those value rose above the dental specification enough to apply for dental materials. However, abrasion resistance was slightly decreased with increasing BaSi content in the filler. Depth of cure value was 6 to 9 mm applicable for dental restoration irrelevant to hybrid filler composition. On the other hand, there was no strict trend between filler composition and polymerization shrinkage as well as degree of conversion.
