Autologous tooth transplantation to replace molars lost in patients with juvenile periodontitis

Abstract
Due to periodontal destruction 15 molars were extracted and then replaced by autologous 3rd molars with incomplete root formation. The patients were then observed for a period up to 7 yr. In all cases complete regeneration of the alveolar bone took place and a normal periodontal membrane was radiographically established. All of the transplanted teeth continued their root formation and there was no radiographic evidence for root resorption, ankylosis or necrosis of the pulp. None of the transplanted teeth displayed pocket depths over 3 mm and no abnormal mobility was detectable.
