Abstract

To simplify the conventional porcelain application procedure, Bonding Porcelainand Opaque Porcelain of Super Porcelain TITAN (Noritake) were blended in this study. Powder of Bonding Porcelain and Opaque Porcelain were blended in weight ratios of 1: 1, 1: 2, and 2: 1, and then applied to titanium (KS50, Kobe Steel) and fired at one time. The bond strength of each compound was measured using the pull-out method. Measurement of color stability was performed in specimens, at variousthicknesses of the porcelain compounds and Body Porcelain, and differences from the standard color were calculated. Values for bond strength were significantlyhigher in compound specimens than “Opaque Porcelain only” specimens. Color stability varied depending on the blending ratio, but no color difference was observed only in monolayer specimens with the blending ratio of 1: 2 and thicknesses of 0.2 mm and 0.3 mm. From these findings, it was considerd that blending ratios hardly make any difference in color stability and that differencce inthe thickness of compound porcelain and Body porcelain affect color stability.
