m-VISTA Technique vs. CAF in the Treatment of Class III Multiple Recessions

Summary

The main objective is to assess whether the percentage of root coverage (%RC) achieved in the treatment of multiples class III recessions using the technique we have called modified vestibular incision subperiosteal tunnel access (m-VISTA), which is a lateral approach subperiosteal tunnel technique, combined with a connective tissue graft is greater than that achieved through the coronally advance flap (CAF) technique together with a connective tissue graft.

Conditions

• Gingival Recessions

Interventions

PROCEDURE

Modified vestibular incision subperiosteal tunnel access

Single vertical mucosal incision, in the middel of the area to be treated, from which we began to lift a mucoperiosteal flap in a single plane. With a micro-scalpel intrasulcular incisions are made extending to the base of the papillas. Preparation of a tunnel in the same plane. Take a connective tissue graft on the same side of the palate. The connective graft is inserted through the vertical incision prepared with the aid of the suture. All is stabilized by means of suspensory sutures of coronal traction on each point of contact. Finally the vertical incision made is sutured.

PROCEDURE

Coronally advanced flap

Oblique submarginal incisions in both interdental areas of each recession, which continue with the intrasulcular incision, one tooth extending on each side of the teeth to be treated. A partial-total-partial thickness flap is elevated in the coronal-apical direction. A vestibular mucosal dissection is performed to eliminate muscle tension. The remnant tissue of the anatomical interdental papillas is desepithelized. Take a CTG on the same side of the palate. The connective tissue graft is stabilized with resorbable suture over the recessions with suspensory sutures on the teeth. Finally, suspensory sutures with non-resorbable sutures are also used to achieve an accurate adaptation of the vestibular flap over the exposed root and stabilize each surgical papilla over each desepithelized interdental area.
