The importance of esthetics has escalated over the years. The purpose of any perioplastic surgery is to address gingival recession while ensuring predictable root coverage and a pleasing appearance. An array of surgical procedures have been recommended for the management of recession defects. The present study compares the clinical and patient related outcome measures of coronally advanced flap with chorion membrane and connective tissue graft in the management of multiple adjacent gingival recessions. The study was a prospective randomized controlled trial which included eight systemically healthy patients with an age range of 30-44 years with 36 labial/buccal, multiple adjacent, Cairo's RT1 gingival recession defects, bilaterally. CAF+CM was performed on one side whereas CAF+CTG was performed on the other side. The two groups were compared clinically at three and six months postoperatively. There was statistically significant decrease in recession depth, recession width, probing depth and clinical attachment level in both the groups from baseline to three and six months. However, intergroup comparisons revealed no statistically significant difference. At six months, both groups showed statistically significant improvements in keratinized tissue width and gingival thickness. The gingival thickness of the CAF+CM group increased significantly at three and six months. In terms of root coverage aesthetic score (RES), there was no significant difference observed between the two groups. In terms of patient reported outcome measures (PROMS), patients preferred the CAF+CM technique. Within the limits of the current study, the use of chorion membrane resulted in considerable root coverage and increased gingival thickness. Periodontal regeneration can be facilitated by the distinctive features of the chorion membrane. Coronally advanced flap plus chorion membrane is a novel approach for root coverage procedures.
这些年，美学的重要性逐渐提升。任何牙周成形术的目的都是在确保可预测的根覆盖和美观的前提下解决牙龈退缩问题。已经推荐了一系列手术程序来管理退缩缺陷。本研究比较了冠向推进瓣与绒毛膜膜和结缔组织移植物在管理多个相邻牙龈退缩中的临床和患者相关结果测量。本研究是一项前瞻性随机对照试验，纳入了 8 名年龄在 30-44 岁之间、有 36 个唇/颊、多个相邻、开罗 RT1 牙龈退缩缺陷的系统健康患者，双侧均有。一侧行 CAF+CM，另一侧行 CAF+CTG。两组在术后 3 个月和 6 个月时进行临床比较。两组从基线到 3 个月和 6 个月时，龈退缩深度、龈退缩宽度、探诊深度和临床附着水平均有统计学显著下降。然而，组间比较没有统计学差异。在 6 个月时，两组的角化组织宽度和牙龈厚度均有统计学显著改善。CAF+CM 组的牙龈厚度在 3 个月和 6 个月时均显著增加。在根覆盖美学评分（RES）方面，两组之间没有观察到显著差异。在患者报告的结果测量（PROMs）方面，患者更喜欢 CAF+CM 技术。在当前研究的范围内，使用绒毛膜膜可获得相当大的根覆盖和增加的牙龈厚度。绒毛膜膜的独特特征可以促进牙周再生。冠向推进瓣加绒毛膜膜是一种新的根覆盖程序方法。
