Summary

Patients with gingival recession, complain of excessive tooth length that affects their appearance during smiling or functioning. The main goal of plastic periodontal surgeries is to restore patient's esthetic demands with the regeneration of gingival and periodontal tissues.

Although SCTG is considered a gold standard, it has its own limitations like patient morbidity and graft availability. Consequently, PRF has been introduced in an attempt to overcome the drawbacks of SCTG and achieve optimum results in root coverage.

The minimally invasive VISTA technique allows better access with coronal positioning and stabilization of gingival margin to achieve complete root coverage. In addition to platelets-rich fibrin that gives a predictable and reproducible result in restoring the amount of keratinized tissue, root coverage and better esthetic outcome. The use Vestibular incision subperiosteal tunneling access (VISTA) with platelet-rich fibrin will be used to achieve complete root coverage.

Conditions

  • Gingival Recession

Interventions

PROCEDURE

VISTA using PRF

Vertical vestibular access incision will be done through the periosteum to elevate a subperiosteal tunnel, exposing the facial osseous plate. The tunnel will be extended beyond mucogingival junction and at least one or two teeth beyond the teeth indicated for root coverage to mobilize gingival margins and allow for low-tension coronal repositioning of the gingiva. Freshly prepared platelet-rich fibrin will be secured in the tunnel to cover the root dehiscence, coronal advancement of gingival margin and suturing to the facial aspect of each tooth to avoid apical relapse of the gingival margin during the initial phase of healing. The vertical incision will be then approximated and sutured
