Abstract
The purpose of this study was to evaluate the effect of the surface treatment of silane coupling agents on the reinforcement of repaired denture and find the optimal condition of silane coupling agent showing highest 3-point flexural strength. Base plate was prepared by heat curing denture base resin, and the region to be repaired was fabricated at the form of Butt Joint. Three kinds of silane coupling agent (3-Methacryloxypropyltrimethoxysilane; MPS, Vinyltriethoxy silane; VTS, 3-Aminopropyltriethoxysilane; APS) was added to the monomer of denture repair resin with 0.1, 0.5, 1.0 and 2.0 % of silane coupling agent. The results of 3-point flexural strength showed that the value of 0.5 % MPS experimental group was higher than that of other MPS groups(P<0.05). The value of 3-point flexural strength of 0.1% VTS group was higher than that of other VTS groups(P<0.05). However, there was no significant difference between the values of each APS experimental group(P>0.05). Therefore, we could conclude that the kinds and concentrations of silane coupling agent are supposed to affect the bond of repaired denture and repair resin.
