Vestibular Incision Subperiosteal Tunneling Approach (VISTA) with Platelets Rich Fibrin (PRF) vs Vestibular Incision Subperiosteal Tunneling Approach (VISTA) alone in multiple recession treatment. A Split mouth Randomized Clinical Trial.

Abstract

Background: Gingival recession treatment is one of the major clinical challenges in periodontics, various surgical techniques were proposed to correct it. Most of these techniques are suitable for isolated recession sites and involve the harvesting of autogenous tissue graft; which increase patient morbidity and might result in inferior esthetics due to incision design. This study assessed the benefit of adding Platelets Rich Fibrin (PRF) to Vestibular Incision Subperiosteal Tunneling Approach (VISTA) in treating multiple gingival recession compared to using VISTA alone. Forty-one teeth with Miller Class I/II were randomized in a split mouth design. Multiple clinical parameters were tested including the change in gingival thickness over time, keratinized tissue width KTW and the gingival phenotype using the transparency of periodontal probe. Patient-centered outcomes were also assessed via Visual Analogue Scale VAS.

Conclusion: Multiple Miller Class 1 and Class 2 recessions in the maxilla can be effectively treated with VISTA. However, when used in conjunction with PRF no significant differences were detected in any parameter. VISTA has been shown to be associated with a low level of pain for patients following surgery and can be used for patients with high esthetic demand.
