Evaluation of resin composite adhesive restoration under clinical conditions

本研究的目的是在临床条件下，检查树脂复合粘接修复的行为。采用模拟口腔环境的组合应力载荷，研究粘接系统的微渗漏、与牙本质表面的拉伸粘接强度以及基于粘接强度的粘接可靠性。对树脂粘接系统与不同牙面（包括临床树脂复合修复预备面）的即刻拉伸强度进行了测定和评价。本研究结果证实了以往国际上对树脂复合粘接修复体的研究中未能阐明的许多客观行为。

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.
