【摘要】：比较二氧化锆全瓷嵌体、钴铬合金高嵌体烤瓷冠和钴铬合金烤瓷全冠修复治疗后牙牙体缺损的临床疗效。选择141例累及邻面的后牙牙体缺损牙齿180颗,随机分成3组,分别制作钴铬合金高嵌体烤瓷冠和钴铬合金烤瓷全冠及二氧化锆全瓷嵌体进行修复,在修复后1年复诊,观察修复效果。高嵌体组和全冠组在修复体完整性、有无继发龋方面与嵌体组比较差异有统计学意义(P0.05),高嵌体组在固位稳定性上更优于全冠组(P0.05)。后牙牙体缺损的修复治疗,全冠、高嵌体冠优于嵌体修复,而高嵌体冠更有利于固位稳定,更加适用于大面积牙体缺损的修复。
[Abstract]:To compare the clinical effect of Zirconia all-ceramic inlay, cobalt-chromium alloy high inlay porcelain crown and cobalt-chromium alloy porcelain crown in the treatment of posterior tooth defect. One hundred and forty-one cases of posterior tooth defects involving adjacent surfaces were randomly divided into 3 groups. Co-Cr alloy high inlay porcelain crowns, cobalt-chromium alloy porcelain crowns and zirconia all-ceramic inlays were made for restoration. Observe the effect of restoration. The restoration integrity and secondary caries in the high inlay group and the whole crown group were significantly different from those in the inlay group, and the retention stability of the high inlay group was better than that of the whole crown group. The total crown and high inlay crown were better than inlay restoration in the repair of posterior tooth defect, while the high inlay crown was more beneficial to the stability of retainer and more suitable for the restoration of large area tooth defect.
