【摘要】 目的探讨应用Strip crowns透明成形冠对大面积龋损的乳前牙进行复合树脂全冠修复的效果。方法 72例174颗大面积龋损的乳前牙分为试验组和对照组。试验组88颗,应用Strip crowns透明成形冠进行复合树脂全冠修复;对照组86颗,用光固化复合树脂直接充填修复。经6个月、18个月随访观察修复体状态。结果经6个月观察,修复体保存率试验组和对照组分别为100%、96.51%,两组间差异无统计学意义(P>0.05)。经18个月观察,修复体保存率试验组和对照组分别为100%、67.44%,两组间差异有统计学意义(P<0.01)。结论应用Strip crowns透明成形冠对大面积龋损的乳前牙进行复合树脂全冠修复,其疗效可靠,明显优于复合树脂直接充填修复,具有良好的应用前景。更多还原

【Abstract】 Objective To study the application of the strip crowns in restoration of multi-surface caries decay in primary anterior teeth.Methods Seventy-two patients with 174 multi-surface caries of primary anterior teeth were divided into group A(control group,86 cases),group B(experimental group,88 cases).Teeth were restored with composite resin in group A and strip crowns in group B,respectively.6 months after therapy,restorations were re-examined at 6-month and 18-month follow-up.Results 6-month retention rate was 96.51% for group A and 100% for group B,with no significant difference between two groups.18-month retention rate was 67.44% for group A and 100% for group B,with significant difference(P<0.01) between two groups.Conclusion Strip crowns is a convenient and effective method to restore the multi-surface caries of primary anterior teeth.更多还原
