Abstract

The purpose of this study was to evaluate the bonding strength between porcelain laminate and Ni-Cr alloy in the various surface treatments of the bonding faces. For this study the metal surface of specimens were treated : 1) etching only, 2) sandblasting only, and 3) sandblasting and etching. The porcelain laminate were made and bonded to the metal specimens with light curing composite resin cement. Instron testing machine was used to measure their bonding strength : and the result was obtained as follows : 1. The bonding strength of the double treatment of the sandblasting and etching group was higher than that of the single treatment of sandblasting or the etching group. 2. The bonding strength of the sand blasting group was higher than that of the etching group. 3. The debonding were mainly occurred between the Ni-Cr alloy and the composite resin cement.
