Comparison of Using Collagen Membrane and A-PRF Using VISTA Technique in Gingival Recession Treatment

Comparative Evaluation of Vestibular Incision Subperiosteal Tunnel Access With Advanced Platelet-rich Fibrin and Collagen Membrane in the Treatment of Gingival Recession Defects

To assess the efficacy of minimally invasive Vestibular Incision Subperiosteal Tunnel Access (VISTA) with collagen membrane and Advanced Platelet-rich Fibrin (A-PRF) in the treatment of multiple buccal gingival recession type 1(RT1) Cairo Classification.

Inclusion Criteria:

• (18-50) years old with at least 2 sites with gingival recession type (RT1) Cairo Classification (GR with no interdental attachment loss). The interdental CEJ is not detectable clinically on the labial surfaces of the teeth.
• Recession in the maxillary anterior region ≥1 mm of attached gingiva, pocket depth (PD) of <3 mm, recession depth (RD) ≥2 mm, and gingival index (GI) score ≤1.
• Systemically healthy, willing individuals with good oral hygiene and without contraindications for surgical interventions

Exclusion Criteria:

• the presence of severe systematic diseases or immunodeficiency and contraindicated with surgical interventions.
• Allergies to medicaments used in the treatment process.
• Patients with removable or fixed dentures.
• Patients with cervical abrasion, direct and indirect restorations involving the cervical areas of the maxillary anterior.
• Participants with smoking, tobacco chewing, and alcohol consumption.
• The presence of high frenal attachment and participants who had previously undergone any periodontal surgical procedure or regenerative therapy in the past 1 year at the same site of the planned treatment.
