Abstract

OBJECTIVE

To evaluate whether microsurgery gains better result in root coverage compared to conventional surgical techniques.

METHODS

A number of databases were searched to identify eligible studies from January 1992 to January 2015.

THE FOLLOWING OUTCOMES WERE EVALUATED

number of sites exhibiting complete root coverage and patients' esthetic satisfaction.

RESULTS

Four Randomized Clinical Trials (RCTs) fulfilled the inclusion criteria. A pooled estimate from the two RCTs regarding sub-epithelial connective tissue grafts (SCTG) showed significant achievement in complete root coverage in the microsurgical group [relative risk (RR):1.63; 95% confidence interval (CI): 1.12 to 2.36; P=0.01] with acceptable heterogeneity. The other two studies were about coronal advanced flap (CAF) with enamel matrix derivative or free rotated papilla autograft and did not qualify for meta-analysis. Patients' esthetic satisfaction was analyzed only by one study.

CONCLUSIONS

Using microsurgical technique for treating gingival recessions may be effective in achieving complete root coverage for SCTG.

摘要

目的

评估与传统手术技术相比，显微外科手术在牙根覆盖方面是否能取得更好的效果。

方法

检索多个数据库，以确定1992年1月至2015年1月期间符合条件的研究。

评估以下结果

显示完全牙根覆盖的部位数量和患者的美学满意度。

结果

四项随机临床试验（RCT）符合纳入标准。两项关于上皮下结缔组织移植（SCTG）的RCT的汇总估计显示，显微手术组在完全牙根覆盖方面取得了显著成果[相对风险（RR）：1.63；95%置信区间（CI）：1.12至2.36；P = 0.01]，异质性可接受。另外两项研究是关于使用釉基质衍生物或游离旋转乳头自体移植的冠向推进瓣（CAF），不符合荟萃分析的条件。仅一项研究分析了患者的美学满意度。
