Summary

Several techniques were proposed in the literature to solve the problems associated with gingival recession. Root coverage was mainly indicated for esthetic concern, however, it might also be indicated for treatment of root hypersensitivity and maintaining adequate plaque control by keratinized tissue augmentation.

These proposed surgical techniques were well-documented with successful outcomes. Each technique had its own advantages, disadvantages and indications. Various factors affected the most suitable technique. These factors were either related to the dimensions of gingival recession defect, or related to the surgeon experience or to the patient himself .

Nowadays, the scope of scientific research is concerned with designing surgical techniques that are more predictable, high esthetic, less invasive and patient centered In this way, continuous modification of surgical techniques aroused to result in a more reproducible outcomes; such as the attempt to advance pedicle flaps without vertical releasing incisions, as in the modified coronally advanced flap and the modified microsurgical tunnel technique.

However, controversy still exist in the literature regarding the best technique for root coverage. Coronally advanced flap is the most commonly reported technique in research, with lack of researches on tunneling techniques.

Conditions

  • Root Coverage
  • Tunneling Technique
  • VISTA Technique
  • Sub Epithelial Connective Tissue Graft

Interventions

PROCEDURE

VISTA (vestibular incision subperiosteal tunnel acess)

A vertical incision will be made on the mucous membrane and the periosteum with a scalpel. The incision will be 8-10mm long, beginning from the mobile mucosa and reaching the apical end of the keratinized gingiva. A small subperiosteal elevator will be inserted through the incision and is used to free the subperiosteal tunnel flap. The flap includes the tissues of the mobile and immobile mucosa in the area of the affected teeth and about 1 mm distally and medially from them. Subperiosteal tunnel will be extended interproximally under each papilla as far as the embrasure space permits, without making any surface incisions through the papilla. Tunneling instruments will be used through the vertical incision to free the mucosa and the periosteum around the teeth affected by the gingival recession. This is continues at the base of the gingival papillae without affecting their integrity.
