The purpose of this research project was to examine the behaviors of resin composite adhesive restoration under clinical condition. Microleakage of adhesive systems, tensile-bond strength to intra-cavity dentin surface and bonding reliability based on bond strength were investigated with combination stress load simulating oral environment. Immediate tensile-bond strengths of resin adhesive systems to various types of tooth surface including prepared surfaces for clinical resin composite restoration were measured and evaluated. From the results, many objective behaviors of resin composite adhesive restoration that had not been clarified by previous researches carried out in the world were confirmed.

本研究的目的是考察树脂复合体粘接修复在临床条件下的行为。采用模拟口腔环境的复合应力载荷，研究粘接剂系统的微渗漏、与牙本质表面的拉伸粘结强度以及基于粘结强度的粘接可靠性。测量和评价树脂粘接系统对不同类型牙面的即时拉伸粘结强度，包括临床树脂复合修复体的预制面。结果证实了树脂复合体粘接修复的许多客观行为，这些行为在国际上的研究中还没有得到澄清。
