Coronally Advanced Flap Combined With Sticky Bone and i-PRF-Coated Collagen Membrane to Treat Single Maxillary Gingival Recessions: Case Series.

Abstract

Numerous techniques have been reported in the literature for the reconstruction of gingival recession defects. The purpose of this case series was to evaluate clinically and radiographically the efficacy of sticky bone with i-PRF-coated collagen membrane in the treatment of gingival recession. Sixteen patients exhibiting isolated Miller's Class I or II recession in the maxillary esthetic zone were treated using sticky bone (i-PRF+freeze-dried bone allograft) with i-PRF-coated collagen membrane using the coronally advanced flap. Clinical parameters including probing depth (PD), width of keratinized gingiva (WKG), gingival thickness (GT), and recession depth (RD) were recorded at baseline and 6 months post-surgery. The radiographic (ST-CBCT) measurements computed were labial plate thickness (OT1, OT3, and OT5) and GT (GT1, GT3, and GT5) at baseline and 6 months post-treatment. Twelve out of sixteen treated cases achieved complete root coverage. An increase in GT was observed in all the cases. Within the limitations of this case series, sticky bone with i-PRF-coated collagen membrane showed promising results in the treatment of isolated maxillary Miller's Class I or II gingival recession and serves as an altered approach for root coverage procedure. However, histological analysis and larger sample size are needed to establish definitive proof of soft and hard tissue regeneration.
