摘　　要：目的探讨采用IPS EmpressⅡ铸造玻璃陶瓷制作高嵌体修复牙冠牙合龈距较短的牙体大面积缺损患牙,并评价其修复效果。方法对37例41颗牙体缺损的患牙,分为实验组和对照组,实验组采用IPS EmpressⅡ铸造玻璃陶瓷制作高嵌体,光固化多功能树脂粘结剂粘结,对照组常规制作金属高嵌体,并进行修复后6、12个月的临床追踪观察,综合美国加州牙科协会制定的全瓷修复临床评定标准,以及刘亦洪对玻璃陶瓷修复体的评价内容并加以补充改进,制定评价标准,做临床评价。结果IPDSEmpressⅡ铸造玻璃陶瓷材料强度高,具有优异的美学特性,高嵌体具有良好的边缘密合性,固位效果良好,能很好地恢复患牙的牙合面解剖形态和邻接关系,牙龈组织无红肿炎症。结论IPS EmpressⅡ铸造玻璃陶瓷高嵌体修复牙体缺损可取得较好的修复效果。Objective To evaluate short term fowllow-up results of castable ceramic-IPS Empress Ⅱ onlays in restoring severe tooth defects with low occlusogingival dimension from clinical aspects. Methods 41 units of the onlay were fabricated and applied in 37 patients, who were divided into experimental group and control group. The experimental group were restored with IPS Empress Ⅱ castable ceramic on lay which was bonded by a dual-cure adhesive system. The control group were restored with mental onlay which was bonded by glass-ionomer cements. All these cases were followed at 6 and 12 months after cementation of the restorations. Metewands were established to evaluate its clinical effects. Results Onlay made from IPS Empress Ⅱ castable ceramic demonstrated natural and esthetical appearance. In addition, proximal contact, retention and marginal fit of the restorations were good. No gingivitis was found. Conclusion The reliability of onlay made from IPS Empress Ⅱ castable ceramic is greatly improved due to the strengthening effects of the lithium disilicate structures. In addition, the better esthetics compared to resin filling technique makes it a comparatively ideal all ceramic system for onlays.
