Figure 1: (a) Preoperative view of the Miller Class I gingival recession on the buccal of the maxillary left canine. (b) A CAF was performed and the soft tissue apical to the root exposure elevated (3.0 to 4.0 mm) full thickness by inserting a periosteum elevator. (c) The vertical incisions were elevated split thickness and the anatomic interdental papillae were deepithelialized to create connective tissue beds. (d) CM was trimmed to extend 2.0 to 3.0 mm beyond the bone crest (both laterally and apically). (e)Collagen matrix fixed with a sling suture over the recession defect. (f) Coronally advanced flap, completely covering the matrix.
