title: Bone regeneration over a poorly-positioned implant to correct an esthetic deformity: a case report.
abstract: Guided tissue regeneration was employed to effect regeneration of a disfigured edentulous ridge, with a poorly positioned implant in place. Demineralized freeze dried bone and an expanded polytetrafluoroethylene membrane were utilized and resulted in growth of new, bone-like material in both a bucco-lingual and apico-occlusal dimension, totally submerging the unusable implant.
