Collagen matrixes have been developed as possible connective tissue graft substitutes to overcome patient discomfort, undesired palatal healing, and the limited amount of donor tissue. The aim of this case series is to assess a coronally advanced flap (CAF) with a new volume-stable collagen matrix (VCMX) to treat single gingival recession (GR) associated with partially restored non-carious cervical lesions (NCCL). Twelve patients diagnosed with single GR RT1 + NCCL (B+) were included in this study and received a restorative – partial resin composite with apical margin 1 mm beyond the estimated cementoenamel junction (CEJ) – and a surgical approach – CAF+VCMX. Clinical and patient-centered assessments were recorded at baseline and 6 months postoperatively from ten patients. Significant recession reduction (RecRed:2.1mm), clinical attachment level gain (CAL:1.34mm), and combined defect coverage (CDC) of 51.67% were observed at 6 months. The estimate root coverage (RC) was 69.48%, obtained using the estimated CEJ. No difference in keratinized-tissue width (KTW) was observed over time. A gain in gingival thickness (GT) of 0.42 mm was observed after 6 months (p=.002) and an improvement in patient satisfaction due to better esthetics (p<.001). Within the present study’s limits, CAF plus VCMX provided significant improvement in treating single GR combined with partially restored NCCL (B+).
