Abstract

AIM

The aim of the present study was to compare the treatment of gingival recession defects using a coronally-advanced flap procedure with or without placental membrane.

METHODS

Sixty teeth in 15 patients with single and multiple Miller's class I and II gingival recession defects bilaterally in the anterior and premolar region of the maxilla and mandible were divided into two groups. In group I (control), 30 recession defects were treated with coronally-advanced flap alone using Zucchelli's technique. In group II (test), 30 recession defects were treated with coronally-advanced flap along with placental membrane. Probing depth, height of the gingival recession (HGR), clinical attachment level (CAL), width of the gingival recession, and width of the keratinized tissue (WKT) were recorded at baseline and 3 and 6 months after the surgical procedures.

RESULTS

There was a statistically-significant reduction in the HGR, gain in the CAL, and WKT in group II compared to group I.

CONCLUSION

Coronally-advanced flap with placental allograft provides a reliable technique for root coverage when compared to coronally-advanced flap alone.

摘要

目的

本研究的目的是比较使用或不使用胎盘膜的冠向复位瓣手术治疗牙龈退缩缺损的效果。

方法

15例患者上颌和下颌前牙及前磨牙区双侧存在单个或多个米勒I类和II类牙龈退缩缺损，共60颗牙齿被分为两组。在I组（对照组），30个退缩缺损仅采用祖凯利技术进行冠向复位瓣治疗。在II组（试验组），30个退缩缺损采用冠向复位瓣联合胎盘膜治疗。在基线以及手术操作后3个月和6个月时记录探诊深度、牙龈退缩高度（HGR）、临床附着水平（CAL）、牙龈退缩宽度和角化组织宽度（WKT）。
