| Research Abstract |
In order to understand the degtadation mechanisms of commercially available ceramic primers,we designed novel ceramic primers,consisting of γ-methacryloyloxypropyltrimethoxysilane (γ-MPTS) and 4-META,MDP or hydrochloric acid (HCl). The ceramic bond durability of resin was examined by measuring the shear bond strength to the ceramic silanated by novel ceramic primers,before and after thermo-cycling. Application of HCl allowed for an increase in the ceramic bond durability more effectively than 4-META or MDP did,since HCl provided greater amounts of protonated proton than 4-META or MDP to accelerate a hydrolysis of the methoxy portion in the silicone-functional group of γ-MPTS. Use of HCl increases the ceramic bond durability of resin.
