title: Management of fused supernumerary teeth in children using guided tissue regeneration: long-term follow up of 2 cases.
abstract: Surgical separation of supernumerary teeth fused to permanent incisor teethhas typically given rise to residual post surgical periodontal defects, induding loss of attachment and deep periodontal pocketing with persistent inflammation. Other complications include devitalisation of the retained tooth section, ankylosis, external and replacement resorption. A unique technique of using guided tissue regeneration has been successfully employed to promote periodontal healing, after 2 cases of surgical removal of a supernumerary tooth fused to a permanent maxillary lateral incisor tooth. In the first case, a 2-stage guided tissue regeneration technique was completed with a nonresorbable Gor-Tex membrane, and was followed up after 9 years. The second case was completed using a resorbable Vicryl membrane, in a single-stage guided tissue regenerative technique; and was followed up after 5 years.
