Embrace树脂和LuxaCoreZ-Dual树脂在纤维桩全冠修复牙冠严重缺损的效果对比

目的:比较Embrace树脂和Luxa Core Z-Dual树脂在纤维桩全冠修复牙冠严重缺损的效果。方法:将116颗牙冠严重缺损的患牙行根管治疗后随机分为两组,A组60颗(前牙39颗,后牙21颗)采用Embrace树脂及纤维桩全冠修复。B组56颗(前牙33颗,后牙23颗)采用Luxa Core Z-Dual树脂及纤维全冠修复,比较两组患牙的修复效果。结果:对所有患者随访3-12月,A组58颗牙修复体完好,失败2颗,成功率为96.66%,其中前牙失败2颗,成功率为94.87%,而后牙成功率为100%;B组54颗牙修复体完好,2颗失败,成功率为96.43%,其中前牙失败2颗,成功率为93.94%,而后牙成功率为100%,两组患牙修复体成功率比较差异无统计学意义(P0.05),4颗修复体的失败均因纤维桩松动脱落所致。结论:Embrace树脂和Luxa Core Z-Dual树脂在纤维桩全冠修复牙冠严重缺损时均具有良好的临床疗效,但Embrace树脂临床操作上更简便。

Comparison of the Effect of Embrace Resin and LuxaCore Z-Dual Resin inFiber Post Crown Restoration of Teeth Crown Serious Defect

Objective:To compare the effect of Embrace resin and LuxaCore Z-Dual resin in fiber post crown restoration of teethcrown serious defect.Methods:116 serious defects teeth after root canal therapy were randomly divided into two groups: Group A of 60teeth, 39 anterior teeth and 21 posterior teeth, using Embrace resin and fiber full crown restoration; Group B of 56 teeth, 33 teeth in frontand 23 posterior teeth, using LuxaCore Z-Dual resin and fiber full crown restoration. The repair effect of teeth was compared between thetwo groups.Results:All patients were followed up for 3-12 months. In Group A 58 teeth were repaired successfully, 2 failed, and thesuccess rate was 96.66%; 2 among which failed in anterior teeth, and the success rate was 94.87%, then the success rate of posterior teethwas 100%; Group B of 54 teeth were successful, 2 failure, the success rate was 96.43%, among which 2 failed in anterior teeth, and thesuccess rate was 93.94%, and the success rate of posterior teeth was 100%. The teeth restoration success rate of the two groups showedno significant difference (P>0.05), 4 restorations failure were due to the loosing of fiber post.Conclusion:Embrace resin and LuxaCoreZ-Dual resin in fiber post crown restoration of teeth crown serious defect both have good clinical effects, but the clinical operationEmbrace resin is more convenient.
