Palatal pedicle flap (Group 1)
Graft + palatal pedicle flap (Group 2)
Provisional ovoid pontic (Group 3)
On patients of this group were performed the palatal pedicle subepithelial connective tissue flap after the extraction, following the technique described by Khoury & Happe (2000), which consists of total detachment of the palatal flap followed by division of the flap to release the connective tissue, maintain a pedicle and sliding it to cover the fresh socket by primary intention. The sutures were removed seven to ten days of postoperative.
On patients of this group were performed the palatal pedicle flap like the group 1, however, the sockets were previously filled with a graft of synthetic bone substitute (Bone Ceramic®, Straumann, Switzerland) and then recovered with the connective flap and sutured by primary intention. The sutures were removed seven to ten days of postoperative.
On patients of this group, after the extraction of the tooth, were made a provisional ovoid pontic with acrylic resin or with the crown of the removed tooth itself, cut and sealed with composite resin. The pontics were placed to seal the entire gingival margin of the socket and penetrating 2 to 3 mm into it, stabilized laterally by the adjacent teeth with orthodontic and composite resin or acrylic resin. No sutures were made.
