Success and failure in tooth transplantation: Three case reports

In young patients autologous tooth transplantations offer a good treatment option in cases of missing teeth or in cases of tooth loss as a sequela of dental trauma. Teeth suited for transplantation are; premolars, which can be transplanted into the anterior or premolar region; or wisdom teeth to replace lost molars. In immature teeth the diameter of the apical foramen must be at least 2 mm wide to pursue revascularisation of the pulp tissue. When a mature tooth is transplanted, root canal treatment will be necessary. On the basis of three case reports, the necessity of interdisciplinary treatment, which includes oral surgeons, endodontists, restorative dentists and orthodontists, has been demonstrated. Inaccurate treatment planning and problems during surgery will significantly reduce the prognosis of the transplanted tooth. Ankylosis, resorption, pulp necrosis or the loss of the transplanted teeth are some of the major complications after transplantation. Thorough treatment planning, gentle surgical technique and a regular checkup are major prerequisites for a good prognosis of tooth transplantation.
