摘　　要：用SMI体视显微镜和片切测量法测定了GI-I型粉浆涂塑铝瓷核冠粘固前的边缘浮出量、粘固后的粘固剂厚度以及代型隙料的厚度.结果表明:粘固前的边缘浮出量为20.38μm;粘固后的核冠整体的粘固剂厚度为39.66μm;采用代型隙料技术,涂刷两层隙料(Vita-Pt interspace vanish,厚度47.33μm),可获得良好的边缘适合性.This study evaluated the adaptation of GI- I slip casting aluminous ceramic core (SCACC). The mean marginal discrepancy before cementatio, the mean thickness of cement after cementation and the thickness of die spacer were measured in vitro using SMI stereomicroscope. The results showed the mean marginal discrepancy before cementation was 20. 38umt the mean thickness of cement after cementation was 39. 66um; a good adaptation of GI- I SCACC could be abtained using die spacer technique (Vita-Pt intervanish, 47. 33um).
