不同方法修复磨牙大面积缺损的疗效比较

［摘要］ 目的探讨钴铬合金烤瓷嵌体、钴铬合金烤瓷全冠和二氧化锆全瓷嵌体修复磨牙大面积缺损的疗效。 方法选取磨牙大面积缺损患者98例共120颗，根据临床修复方式不同，将其分为钴铬合金烤瓷嵌体修复组、钴铬合金烤瓷全冠修复组和二氧化锆全瓷嵌体修复组，各40颗，患牙修复后1年复诊观察修复效果。 结果钴铬合金烤瓷嵌体修复组在修复体固位稳定性方面明显优于钴铬合金烤瓷全冠修复组（P＜0.05）。钴铬合金烤瓷全冠修复组在修复体完整性、继发龋方面明显优于氧化锆全瓷嵌体修复组（P＜0.05）。钴铬合金烤瓷嵌体修复组在修复体完整性、边缘密合度、颜色匹配性、继发龋方面明显优于二氧化锆全瓷嵌体修复组（P＜0.05）。 结论钴铬合金烤瓷嵌体和钴铬合金烤瓷全冠修复磨牙大面积缺损的疗效明显优于二氧化锆全瓷嵌体修复，且钴铬合金烤瓷嵌体修复在固位稳定性方面效果更佳，更适合磨牙大面积缺损的修复。

Comparison of the effects of different methods on repairing large area defects of molars

［Abstract］ ObjectiveTo investigate the curative effect of cobalt-chrome alloy inlayed porcelain crown, cobalt-chromium alloy porcelain crown and zirconia all-ceramic inlay. 〖WTHZ〗MethodsA total of 120 patients with large area defects were treated with a total of 98 patients with a large area defect. According to the random number table method, it was divided into cobalt-chromium alloy high-inlay porcelain crown repair group, cobalt-chromium alloy porcelain crown restoration group and zirconium dioxide all-ceramic inlay repair group, each group of 40, suffering from dental restoration after one year visit to observe the repair effect.〖WTHZ〗ResultsThe chrome-chrome-coated porcelain-fused-to-metal crowns were better than those of cobalt-chromium alloy porcelain crowns(P＜0.05). Cobalt chromium alloy porcelain crown repair group was superior to zirconia all-ceramic inlay repair group in restoration body integrity, secondary caries and color matching(P＜0.05). The effect of Cobalt-chrome-based high-embedded porcelain-fused-to-metal crown restoration group was better than that of zirconia all-ceramic inlay repair group(P＜0.05). 〖WTHZ〗ConclusionThe effect of cobalt-chrome-plated inlay porcelain crown and cobalt-chromium alloy porcelain crown are better than that of zirconia all-ceramic inlay repair, and cobalt-chrome-based inlay retention stability in terms of better results, more suitable for repair of large area defects after the molar.
