About

Clinical evaluation of conventional and modified coronally advanced flaps combined with acellular dermal matrix graft

Full description

The aim of this study was to evaluate the effectiveness of vertical incisions in the management of multiple gingival recessions (Miller Class I&II ≥3 mm) treated with coronally advanced flap (CAF) and acellular dermal matrix graft (ADMG) in 22 eligible participants.

Coronally advanced flap and acellular dermal graft

Active Comparator group

Description:

In CAF group, after local anesthesia oblique beveled vertical incisions were made at the most mesial and distal line angles of the recessions. These two incisions were connected with an intra-sulcular and interdental sub-marginal incisions in order to create the external surgical papillae. Then the flap was elevated as a split-full-split approach. The apical portion of the flap was reflected as close to the periosteum as possible by mesio-distal and apical sharp dissection parallel to the mucosa to release residual muscle tension and extended beyond the muco-gingival junction to facilitate the passive coronal replacement of the flap over the defects. In both groups ADMG was used as a sub-epithelial graft considering the manufacturer's instructions. The graft was positioned at the level of cemento-enamel junction and extended to the surrounding bone in the apical direction with full closure of the exposed root surfaces.
