CAD/CAM全锆冠与钴铬烤瓷冠修复的临床短期疗效观察

A short term clinical evaluation of CAD/CAM zirconia crown and porcelain Co-Cr crown in restoration of teeth

目的评价氧化锆全瓷冠与钴铬烤瓷冠修复牙体缺损的短期临床效果。方法本研究选取80例牙体缺损的患牙,于牙体治疗后分别采用氧化锆全瓷冠,钴铬烤瓷冠进行修复,在修复后的6、12个月时,观察其临床修复效果。结果观察期间,两组修复体外形均保持良好,而氧化锆全瓷冠在美观效果、牙龈健康状况方面优于钴铬烤瓷冠。结论氧化锆全瓷冠具有更好的临床修复效果。

Objective To evaluate the short term clinical performance of crowns, respectively constructed with CAD/CAM zirconia and porcelain Co-Cr.Methods Eighty defected teeth were selected, and then restored with CAD/CAM zirconia and porcelain crowns after endodontically treatment. Each crown was reviewed in six, twelve months after its placement.Results All the crowns were intact, while the color matching and the gingival condition in zirconia crowns were better than the other group.Conclusion The clinical performance of the CAD/CAM zirconia crowns is optimal.
