摘　　要：应用体视显微镜观测新型的ＣＥＲＥＣⅡ型机制作的瓷嵌体与离体人牙粘接前后的适合性。结果表明：粘接前，洞型与嵌体轴壁间隙（６７±１８μｍ），龈壁间隙（８４±２２μｍ），面平均间隙５８．５μｍ；粘接后，平均边缘浮升量（３９±１６μｍ），粘接剂厚度在轴壁（１１８±３７μｍ），龈壁（１２３±１７μｍ），面平均厚度８０μｍ。提示：ＣＥＲＥＣⅡ型机制作的瓷嵌体具有良好的适合性。The purpose of this in vitro study was to investigate the marginal and internal fit of Cerec2 inlays before and after adhesion. The test showeed: ①Before luting, the axial marginal space was 67±18μm, cervical marginal space was 84±22μm and the mean occlusal marginal space was 58μm. ②After luting, the thickness of the luting composite was 118±37μm at axial margin, and 123±17μm at cervical margin, the mean occlusal margin space was 80μm. This study demonstrated the marginal adaptation of Cerec2 inlays satisfied the clinical demand, especially at occlusal margin.
