| Research Abstract |
The aim of this investigation was to evaluate the effect of silica coating with Perhydropolysilazane (PHPS) on the resin bonding to yttria-stabilized zirconia (Y-TZP) ceramic. Two 5% PHPS solutions (NP-110, NL-120) were evaluated in this experiment in order to obtain an effective heating program and, optimum conditionings to heated silica. Relatively high bond strengths were achieved by heating at 500℃ regardless of PHPS solution or heating time. Especially, significantly higher bond strength was obtained for silica-coated with NL-120 (500℃, 10m) containing Pd-catalyst followed by VUV irradiation (185nm, 10m). New PHPS coating technology is an effective adhesive method for bonding resin to Y-TZP ceramic.
