近年来要求用牙齿颜色的修复材料修复牙体的患者增多。由于传统的复合树脂不耐磨、易折断和易产生继发龋,使用于后牙受到限制,用金属烤瓷或全瓷冠修复需切割牙体组织较多,陶瓷嵌体的临床性能比传统的复合树脂好而受到欢迎。目前对陶瓷嵌体使用寿命的报道很少,本文对25例陶瓷嵌体修复后的使用寿命进行了报道和评价。 作者在1989年2月～1992年3月期间,考察了25个陶瓷嵌体,平均修复时间为40.4月。在这25个陶瓷嵌体中,13个修复在双尖牙上,12个修复在磨牙上。紧咬牙、磨牙症、过度磨损、严重牙周炎、口腔卫生很差、

Due to the traditional composite resin is not wear-resistant, easy to break and easy to produce secondary caries, used in posterior teeth is limited, with porcelain or ceramic porcelain crown to be cut to be cut more tissue, the clinical performance of ceramic inlays than the traditional The composite resin is good and welcome. At present, there are few reports on the service life of ceramic inlays. This article reports and evaluates the service life of 25 ceramic inlays after repair. The authors examined 25 ceramic inlays from February 1989 to March 1992 with an average repair time of 40.4 months. Of the 25 ceramic inlays, 13 were restored on bicuspid teeth and 12 on molars.
