Oral Surgery closure of a buccal dehiscence – cheek side opening in the gums – on an upper lateral incisor tooth. How to pictures. Photo 1) The initial presentation with the lateral incisor tooth root exposed and with tooth decay cavity up to the root apex. Photo 2) Surgical exposure of the site after tooth root extraction. A full thickness mucoperiosteal gum flap with bucco-lingual vertical releasing incisions was used to obtain primary closure. The socket was curetted and freeze-dried cortical chips – bone graft – were placed with Biomend membrane. Photo 3) Primary surgical closure was obtained with 3-0 Vicryl sutures stitches. Photo 4) The final result after fabrication of the porcelain-metal fixed teeth bridge.
