Gingival recession is one of the most common esthetic and functional concerns associated with periodontal tissues. Several techniques have been described to cover the exposed root surface. The aim of the present study was to evaluate the efficacy of recession coverage using a coronally repositioned flap in conjunction with a bioresorbable collagen membrane.
Eight non-smoking healthy subjects with Miller's Class I and II recession defects in the maxillary anterior region were selected. Recession was treated by a coronally repositioned flap along with a bioresorbable type I collagen guided tissue regeneration membrane (Periocol®). Clinical parameters recorded were recession depth, recession width, width of keratinized tissue, and width of the attached gingiva at baseline and 3 months postoperatively.
Three-month postoperative measurements demonstrated significant root coverage and a reduction in the recession depth and width. In addition, there was a significant increase in the width of keratinized tissue and of the attached gingiva.
Recession coverage with a coronally repositioned and bioresorbable collagen membrane demonstrated good results in terms of root coverage as well as increase in the width of keratinized tissue.
牙龈退缩是牙周组织最常见的美学和功能问题之一。已经描述了几种技术来覆盖暴露的牙根表面。本研究的目的是评估使用冠向复位瓣联合生物可吸收胶原膜进行牙龈退缩覆盖的效果。
选择 8 名上颌前区 Miller Ⅰ类和Ⅱ类退缩缺损的非吸烟健康受试者。采用冠向复位瓣联合生物可吸收 I 型胶原引导组织再生膜（Periocol®）治疗退缩。记录基线和术后 3 个月的临床参数包括：退缩深度、退缩宽度、角化组织宽度和附着龈宽度。
术后 3 个月的测量结果显示，根覆盖有显著改善，退缩深度和宽度减小。此外，角化组织和附着龈的宽度也显著增加。
用冠向复位瓣和生物可吸收胶原膜进行牙龈退缩覆盖在根覆盖以及角化组织宽度增加方面取得了良好的效果。
