摘要： 目的:比较两种不同材质的牙色改良高嵌体/冠修复中重度后牙缺损的临床疗效。方法:对46名患者51颗中重度缺损后牙分别采用CAD/CAM氧化锆全瓷改良高嵌体(冠)(A组)及钴铬烤瓷改良高嵌体/冠(B组)修复,在修复后12、24个月分别进行回访观察,比较其修复效果。结果:B组有1例在24个月回访时发现边缘瓷层崩瓷,边缘密合度增加,修复体未见损坏、松动,患牙未见继发龋及折裂,7颗修复体与患牙或邻牙颜色轻度不匹配。A组有3颗修复体与患牙或邻牙颜色轻度不匹配,其余未见异常。结论:两种不同材质的牙色改良高嵌体/冠用于中重度后牙缺损的修复效果均较理想,兼顾了修复体的强度与美观, 在选好适应症的情况下,简化了疗程,且临床疗效较好,但由于本研究观察期较短,远期效果有待进一步观察。

Abstract: Objective: To compare the clinical effects of two tooth-colored improved onlay/crown restorations in the seriously damaged molars. Methods: A total of 51 onlay/crowns restorations were placed in 46 patients. The restorations were allocated into CAD/CAM zirconia ceramics and Co-Cr PFM onlay/crowns. According to modified USPHS criteria, all improved onlay/crowns were checked and recorded at 1 week, 1 year and 2 year after the restorations were placed. Results: Only one Co-Cr PFM onlay restoration was broken on the ceramic layer at the second year. There were no restoration loss, tooth fracture and secondary caries during the study. Three CAD/CAM zirconia ceramics and 7 Co-Cr PFM restorations were little mismatch in color with adjacent teeth. Conclusion: Improved tooth-colored onlay/crown restoration provides the dentists with another treatment choice for seriously damaged posterior teeth. However, long-term observation is necessary.
