Implantattherapie nach Frontzahntrauma - Eine neue Methode zum Erhalt des Alveolarkammes nach posttrauma­tischer Ankylose und externer Wurzelresorption

The therapy of traumatized front teeth with ankylosis and additional root resorption is a real challenge for the clinician. Due to the infraposition ankylosed teeth are useless and esthetically unsatisfactory. The progressive replacement resorption and the vertical growth inhibition render an intervention inevitable. In the following case report, the prophylaxis of the alveolar ridge is brought into focus. The treatment of two ankylosed teeth by decoronation, preservation of the alveolar ridge and an implant-supported supraconstruction will be presented. The additional histological assessment confirms the diagnosis and the choice of treatment.
