Effects from Applying Adhesive Agents onto Silanated Porcelain Surface on the Resin Bond Durability

Abstract

This study examined the effects on the bond durability of resins arising from the application of adhesive agent on porcelain surface, silanated by a ceramic primer consisting of γ-methacryloxypropyltrimethoxysilane (γ-MPTS), by comparing shear bond strengths before and after thermocycling. When an adhesive agent was applied to a porcelain surface which had been silanated by a ceramic primer for 10 seconds, a significant reduction in resin bonding durability was observed. Extending the silanating period of the ceramic primer to 60 minutes resulted in an increase in resin bonding durability to the porcelain surface. However, the effect on resin bonding durability resulting from the application of adhesive agent was nearly the same as that without adhesive agent application, even though the porcelain surface was silanated for 60 minutes. In other words, positive effects arising from adhesive agent application on resin bonding durability were not observed.

Effect of storage time on chemical structure of a single-bottle and a two-bottle experimental ceramic primer and micro-shear bond strength of composite to ceramic

“…For preparing ceramic substrates in this study, just ceramic primer was used to avoid interfering factors such as damage to the ceramic surface and even fracture possibility due to pressure caused by mechanical methods such as sandblasting, silica coating or acid etching. 12 It is also reported that by using phosphate monomers as activator in ceramic primer solution 13 or silane, 14 pretreatment of ceramic surface with acid does not increase the durability of the resin cement bond to silicon oxide ceramics.…”

“…Porcelain-fused metal crowns (PFMs) and all-ceramic crowns are commonly used for prosthetics or esthetic restoratives in anterior and molar teeth. The porcelain for PFMs and the porcelain structure of all-ceramic crowns is brittle and can be easily fractured, but a resin composite can be used to effectively repair the fractured porcelain [1][2][3].…”
