Coronally Advanced Flap With Two Different Techniques for the Treatment of Multiple Gingival Recessions

Performed by using horizontal interdental incisions. An initial horizontal incision was made slightly coronal to the CEJ from the distal to the mesial papilla of the teeth with the recessions. A second incision, 1 to 2 mm apart and parallel to the first incision, was made apically. A sulcular incision was made to link the second incisions and the blade was inserted (2 to 3 mm) extending beyond the mucogingival junction (MGJ), to create a uniform split-thickness flap. The tissue between the two incisions was partially removed to obtain a uniform receptor site that permitted primary closure. Approximation sutures to place the edge of the flap at the base of the remaining papilla were performed. Passive closure of the wound margins without tension was achieved with interrupted coaptation.

Coronally advanced flap was performed by using oblique incisions in interdental areas, according to the technique proposed by Zucchelli \& De Sanctis (2000). Oblique submarginal interdental incisions were performed and continued with the intrasulcular incisions at the recession defects, resulting in a envelop flap that was raised with a split-full-split approach in the coronal-apical direction. During coronal advancement, each surgical papilla was dislocated with respect to the de-epithelized anatomic papilla by the oblique incisions. Interrupted sutures were performed to stabilize single surgical papilla over the interdental connective tissue bed.
