The purpose of this research project was to examine the behaviors of esthetic metal-free adhesive restorations under clinical combinations. Microleakage of the restorations, tensile-bond strength to intra-cavity dentin surface and bonding reliability based on bond strength under combination stress simulating intra-oral environment were investigated. Tensile-bond strengths of resin adhesive systems to various types of tooth surface prepared clinically were measured with an in vivo/in vitro portable adhesion tester and evaluated.From the obtained results, many objective behaviors of metal-free adhesive restorations, that were not clarified by previous researches carried out in the world, were confirmed.

本研究项目的目的是检查临床组合下美学无金属粘合剂的行为。在模拟口腔内环境的复合应力作用下，研究了牙本质表面的微渗漏、牙本质表面的抗拉强度以及基于抗拉强度的粘接可靠性。用便携式体内/体外粘附力测定仪测定了树脂粘结系统与临床制备的各种牙面的拉伸粘结强度并进行了评价，从所得结果中证实了国际上以往研究中未阐明的无金属粘结剂的许多客观行为。
