Gestion de l'ankylose alvéolo-dentaire et procédure de décoronation

Abstract : A dentoalveolar ankylosis is a solid fixation of a tooth resulting from fusion of the cementum and alveolar bone with obliteration of the periodontal ligament. It may appear after a severe trauma, in particular following an important intrusion or after an avulsion with a delayed replantation. It is associate with a replacement resorption, it means that the root gradually disappeared in favour of the alveolar bone. It could cause various adverse effects for the patient and it is impossible to stop it. We can use several treatments more or less conservative. We are developing here one of this therapy : the decoronation of the ankylosed tooth. It is about removing the dental crown and the root canal filling and let the root inside the alveolar bone, covered by a mucoperiosteal flap in order to preserve the bone volume. The purpose of this work is to identify if this therapeutic is interesting and in witch case. In the first instance we will develop the ankylosis process and is diagnosis and talk about is pathogenesis and is consequences on these young children, and we will see the several existing treatments. Secondly, we will talk specifically about the decoronation of the concerned tooth. We will try to determinate what is the interest of this practice, its specific indications, and what are the clinical steps.
