Platelet-rich fibrin-reinforced periosteal pedicle graft with vestibular incision subperiosteal tunnel access technique for the coverage of exposed root surface

Abstract

Platelet-rich fibrin (PRF) has been shown to promote soft tissue healing because it contains growth factors. Periosteal pedicle graft (PPG) provides not only good and predictable root coverage, but also reduces the need for the second surgical site. Access to the surgical site is obtained by minimally invasive technique known as vestibular incision subperiosteal tunnel access (VISTA) technique. Therefore, the purpose of this case report was to evaluate the PRF-reinforced PPG with VISTA technique for the coverage of exposed root surface. A patient with Miller Class II gingival recession of 6.5 mm was treated by PRF-reinforced PPG with VISTA technique. PRF was prepared from whole blood and applied to the root surface. After 6 months, 5.5 mm, that is, 84.6% of the root coverage was obtained. PRF-reinforced PPG with VISTA technique can be predictably used for the achievement of successful root coverage. The long-term follow-up with histologic studies will be required to obtained more information about PRF-reinforced PPG with VISTA technique for the coverage of exposed root surface. Clinical Relevance to Interdisciplinary Dentistry PRF is a fibrin matrix network in which platelets are trapped. Platelets in PRF release high amount of growth factors which take part in soft tissue and hard tissue repair and regeneration. As PRF-reinforced PPG and VISTA technique for coverage of exposed root surface showing good promising results, PRF can be used in various aspects/disciplines of the dentistry as well as in interdisciplinary dentistry to reinforced natural tissue regeneration (NTR) and natural bone regeneration (NBR).
