Notes:
This study was conducted to evaluate shear bond strength between self-made alumina glasscomposites (AGC), zirconia glass composites (ZGC) and Vita alpha opaque-dentine porcelain, and alsoevaluate the effects of different surface treating methods on the bond strength. The AGC and ZGCspecimens were treated differently and then bonded with Vita alpha opaque-dentine porcelain. The bondstrength was measured by shear test and the surface treating methods included no-treatment, sandblastingand etching. The results showed that the values of bond strength for AGC groups were 30.1, 41.1 and 41.9MPa respectively, and the bond strength of both sandblasting group and etching group were significantlyhigher than that of the untreated group; the bond strength of ZGC groups were 60.2, 63.6 and 35.5MParespectively, and the value of sandblasting group was significantly higher while etching group was lowerthan that of untreated group. These results indicated that Vita alpha opaque-dentine porcelain can be wellsintered to self-made AGC and ZGC. Sandblasting can greatly improve the bond strength for both AGCand ZGC, while the etching treating method had different effect on their bond strengths
