Abstract
Background: Gingival recession is a frequent finding in patients. The connective tissue graft plus coronally advanced flap (CTG+CAF) is considered the gold standard for root coverage therapy. An alternative option, both avoiding the need for palatal donor tissue and allograft material, is the use of collagen matrix (CM) of porcine origin. Methods: The aim of this report is to describe a surgicalutilizing collagenmatrix plus coronally advanced flap (CM+CAF) in a 3 mm buccal gingival recession associated to traumatic brushing in the maxillary left canine. The goal of treatment was determines if a CM with CAF might be as effective in the root coverage procedure of Miller?s class I recession defect. Results: Gradual surgical healing with minimal postoperative morbidity and very slight discomfort was observed at 1 week. The clinical observation at 12-months revealed complete root coverage with an adequate zone of keratinized tissue with good healing, color, and texture nicely at the native adjacent soft tissues. Conclusions: Patient satisfaction and esthetics was very high. The results seem to suggest that CM+CAF can provide a valid treatment procedure in root coverage. Moreover, it has shown a significant reduction in surgery time, maintenance of marginal tissue health, and mainly patient morbidity without the graft harvest.
Highlights
The treatment of gingival recession is a common requirement due to aesthetic concern or root sensitivity in patients with high standards of oral hygiene [1]
Gingival recession is defined as an apical shift of the gingival margin from its position 1 mm coronal to or at the level of the cemento-enamel junction (CEJ) with exposure of the root surface to the oral environment [2]
Outcomes have been reported by adding a connective tissue graft to the coronally advanced flap (CAF+CTG)
Summary
The treatment of gingival recession is a common requirement due to aesthetic concern or root sensitivity in patients with high standards of oral hygiene [1]. The coronally advanced flap (CAF) is a very common approach for root coverage, the surgery does not involve a palatal donor site, and it was demonstrated to be a safe and predictable. The connective tissue graft plus coronally advanced flap (CTG+CAF) is considered the gold standard for root coverage therapy. An alternative option, both avoiding the need for palatal donor tissue and allograft material, is the use of collagen matrix (CM) of porcine origin
