Use of a Novel Volume-stable Collagen Matrix (VCMX) in the Treatment of Single Gingival Recession Associated With Non-carious Cervical Lesion Partially Restored
Gingival Recession, Localized, Tooth Abrasion
About this trial
This is an interventional treatment trial for Gingival Recession, Localized focused on measuring Gingival Recession, Tooth Abrasion, Biomaterials
Eligibility Criteria
Inclusion Criteria: adult > 20 years old; systemically healthy no signs of active periodontal disease; full-mouth plaque and bleeding score ≤20%; Gingival recession type RT1 associated with NCCL B+ on a vital canine or premolar; Exclusion Criteria: Patients who had had periodontal surgery on the study area; Smokers patients; Pregnant or lactating patients; Ongoing orthodontic treatment; Patients taking medications known to interfere with the wound healing process or that contraindicate the surgical procedure

Partial restoration will be performed, and its apical margin will be placed 1 mm beyond the estimated position of the cementoenamel junction. Patients enrolled in this group will receive a coronally advanced flap (CAF). Two horizontal incisions will be performed at the papilla base united by an intrasulcular incision around the tooth. In sequence, releasing incisions will be designed and a split-full-split flap will be raised beyond the mucogingival junction. Sling sutures will be placed to stabilize the flap margin 2 mm coronal to CEJ, followed by interrupted sutures to close the releasing incisions.

In sequence, releasing incisions will be designed and a split-full-split flap will be raised beyond the mucogingival junction. In sequence, VCMX will be cut according to the recession defect and moistened with saline solution. The biomaterial will be placed at the cementoenamel junction level and stabilized in the adjacent surgery papillae by interrupted sutures. Then, sling sutures will be placed to stabilize the flap margin 2 mm coronal to CEJ, followed by interrupted sutures to close the releasing incisions.
