CAD/CAM全瓷髓高嵌体在牙体缺损中的临床应用研究

Abstract

Abstract: Objective　 To evaluate clinical effects of CAD/CAM ceramic Endo-onlay restoration in the posterior teeth after root canal treatment. Methods 82 completed endodontically treated posterior teeth from 71 cases, including 33 males and 38 females, aged 20-50 years old, were restored with IPS e.max CAD Endo-onlays.Then the color, shape, fracture , marginal discrepancy, secondary caries and food impaction status were assessed after a 24-month follow-up.Results During the follow-up, 4 were missing among 82 dental restorations, among which 78 met the class A standards for shape and secondary caries. 1 was fractured and 4 appeared to have food impaction, more than 95% were scored grade A. Conclusion CAD/CAM ceramic Endo-onlay has good clinical effect in restoration of endodontically treated posterior teeth.

Key words: CAD/CAM, IPS e.max CAD Endo-onlay, posterior teeth, Tooth Defect
