Coronally Repositioned Flap with Bioresorbable Collagen Membrane for Miller's Class I and II Recession Defects: A Case Series.

Objective: 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.

Methods: 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.

Results: 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.

Conclusion: 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.
