| Research Abstract |
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.
