The ultimate goal of any periodontal plastic surgery aimed to treat gingival recession is predictable recession coverage and esthetic outcome. Due to the post-operative morbidity and discomfort related to subepithelial connective tissue graft, various other methods have been introduced including the use of fetal membranes. The fetal membranes have shown promising results in medicine and recently in the field of regenerative dentistry and could possibly become a viable alternative to autogenous grafts. This article reports a series of cases of Miller's class I gingival recession that were treated by chorion membrane combined with coronally advanced flap and evaluated using objective variables for post-operative healing and esthetics. Nine systemically healthy subjects with ten Miller's class I buccal gingival recession were included in the study. Clinical parameters were recorded at baseline, 3 months and 6 months post-surgery; wound healing index (WHI) was recorded one week post-surgery. At the end of 6 months, the percentage of root coverage and the root coverage esthetic score (RES) were calculated. The results showed statistically significant (p < 0.05) improvement in most of the parameters. The mean percentage of root coverage obtained was 62.20 ± 21.99% ranging from 33.3 to 100%. The WHI showed excellent healing score and RES assessed at the end of six months showed superior esthetic results. The chorion membrane along with coronally advanced flap is a predictable procedure for root coverage with better post surgical healing and superior esthetics.
任何旨在治疗牙龈退缩的牙周整形手术的最终目标都是可预测的退缩覆盖和美学效果。由于与上皮下结缔组织移植相关的术后发病率和不适感，人们引入了各种其他方法，包括使用胎膜。胎膜在医学领域以及最近在再生牙科领域都显示出了有前景的结果，并且可能成为自体移植的可行替代方案。本文报告了一系列采用绒毛膜联合冠向推进瓣治疗的米勒I类牙龈退缩病例，并使用客观变量对术后愈合和美学效果进行了评估。该研究纳入了9名全身健康的受试者，他们共有10处米勒I类颊侧牙龈退缩。在基线、术后3个月和6个月记录临床参数；术后1周记录伤口愈合指数（WHI）。在6个月末，计算牙根覆盖百分比和牙根覆盖美学评分（RES）。结果显示，大多数参数有统计学意义（p < 0.05）的改善。获得的牙根覆盖平均百分比为62.20±21.99%，范围为33.3%至100%。WHI显示出优异的愈合评分，6个月末评估的RES显示出卓越的美学效果。绒毛膜联合冠向推进瓣是一种可预测的牙根覆盖手术方法，术后愈合更好，美学效果更佳。
