Introduction
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.
Case Series
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.
Conclusions
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.
Saddle flap technique, a modified coronally advanced flap approach for isolated gingival recession management was introduced and assessed in terms of clinical efficacy and patient satisfaction. A total of 10 systemically healthy subjects with isolated gingival recession defect (Miller Class I and II) were enrolled in the study. The primary endpoint measure was patient satisfaction in terms of esthetics and percentage root coverage. The secondary outcome measures comprised clinical attachment level change, gingival thickness variation, width of keratinized tissue alteration, and postoperative healing. At 1 year postoperative, 80% of the treated sites achieved 100% root coverage. Based on clinical results, saddle flap technique could be considered as one of the possible treatment options for isolated gingival recession with good esthetic and patient satisfaction.
