Dental membranes used in the oral surgery closure of a buccal dehiscence on an upper lateral incisor tooth. 1) The initial presentation with the lateral incisor root exposed and a tooth cavity up to the root apex. 2) Surgical exposure of the site after extraction of the tooth root. A full thickness mucoperiosteal flap of the gums with bucco-lingual vertical releasing incisions was used to obtain primary closure. The tooth socket was curetted – cleaned out – and freeze-dried cortical bone graft chips were placed with Biomend membrane. 3) The oral surgeon obtained primary closure of the wound with 3-0 Vicryl sutures. 4) The final result after fabrication of the teeth bridge.
