The aim of this study was to evaluate the shear bond strength of three luting cements and to identify the effect of thermocycling. Zirconia discs were made similar to the inner surface of a preformed pediatric zirconia crown (

지르코니아의 특징은 무엇인가? | 지르코니아는 안정한 화학구조로 생체적합성이 뛰어나고 단단하며 마모 저항성이 크다. 이러한 우수한 물성으로 인해 성인에서 도재전장관, 고정성 국소의치, 임플란트 지대주 등 넓은 범위에서 다양한 목적으로 사용되고 있다[1-3]. | |
소아용 기성 지르코니아 전장관의 사용이 증가하는 이유는 무엇인가? | 최근 소아치과에 내원한 환자 보호자들의 심미적 요구가 증가함에 따라 유치 수복재료로 소아용 기성 지르코니아 전장관이 개발되었다[4,5]. 다른 유치 전장관에 비해 외관상 자연스럽고 강도가 높으며 변색 저항성이 뛰어나다는 장점이 있어 사용이 증가하고 있다[6]. | |
RUR은 어떻게 화학적 결합을 이루는가? | RUR은 주로 methacrylate phosphoric acid로 이루어져 있어 인산기의 친수성 성분이 치면과 전처리 과정없이 화학적 결합을 이룬다. 산성의 인산기가 필러의 알칼리 성분과 중화반응을 이루어 높은 강도의 결합력을 나타내어 3종의 시멘트 중 가장 높은 전단결합강도를 보인 것이라 생각된다[24]. |
