Abstract： Objective　To investigate the matching between selfmade alumina-glass composite and Vita alpha veneering ceramic. Methods　By using thermal shock test and SEM. Results　The crazing resistance of alumina glass composite via Vita alpha ceramic expressed as the mean ΔT was 170 ℃. SEM micrograph indicate that Vita alpha ceramic fused to alumina glass composite, and no crack between the combination interface. Conclusion　alumina-glass composite can match to the Vita alpha ceramic fairly.
