应用弧形成型片与条状聚酯薄膜成型片进行树脂修复黑三角临床效果对比分析

Comparison Analysis of Clinical Efficacy in Resin Restoration of Black Triangles Using Curved Sectional Matrices versus Strip-Shaped Polyester Matrix Forming Films

摘要: 目的：探讨应用弧形成型片与条状聚酯薄膜成型片进行树脂修复黑三角的疗效对比。方法：选取符合纳入标准的20例(共80颗患牙)正畸后下切牙区存在黑三角的女性患者，采用随机数字表法分为治疗组和对照组两组，每组各10例。治疗组使用Bioclear弧形成型片辅助进行树脂充填修复，对照组使用条状聚酯薄膜成型片辅助进行树脂充填修复。在充填后3个月、6个月由另一名医师进行复查，比较两种成型片的疗效。结果：两组病例医生临床操作时间治疗组用时更短(P < 0.05)，充填后3个月、6个月随访两组成功率相似，两组比较无显著性差异(P > 0.05)。结论：Bioclear成型片效果优于条状聚酯薄膜成型片，医生临床操作简便，远期复查疗效稳定，值得广泛推广。

Abstract: Objective: Comparative analysis of the efficacy of Bioclear and strip-shaped polyester matrix forming films in resin restoration of black triangles. Method: Twenty female patients (80 teeth in total) with black triangles in the lower anterior teeth area after orthodontic treatment, who met the inclusion criteria, were selected. They were randomly divided into two groups, with 10 cases in each group. The treatment group underwent resin filling restoration with Bioclear-assisted resin, while the control group underwent resin filling restoration with strip-shaped polyester matrix forming films. Another dentist conducted follow-up examinations at 3 months, and at 6 months post-filling to compare the efficacy of the two types of forming films. The clinical operation time was shorter in the treatment group compared to the control group (P < 0.05). The success rates in both groups were similar at 3 months and 6 months post-filling, with no significant difference between the two groups (P > 0.05). Conclusion: The efficacy of Bioclear forming films is superior to strip-shaped polyester matrix forming films. The clinical operation is more convenient, and the long-term follow-up efficacy is stable, indicating widespread promotion.
