Indications d'extractions précoces de premières molaires permanentes

Abstract : The first permanent molar represents the cornerstone of the manducatory apparatus by its predominant role in the various occlusal and masticatory functions as well as in the growth of the dental arches. However, due to its susceptibility to various caries diseases, it can be extracted very early in a young patient. Ideally, tissue conservation and preservation are preferred. However, certain endodontic or periodontal complications can compromise the conservation of this tooth placing the practitioner in front of a difficult choice. In this context, many factors will have to be studied such as the age of the patient or the presence of dento-maxillary dysharmonies. In this case, extractions may be a way to resolve malocclusions, especially in cases of Angle class 2 or 3. To replace the first molar, the orthodontist has many approaches. Closure by distalization of the lateral sectors or mesialization of the posterior sectors associated or not with skeletal anchors. Opening by ortho-prosthetic treatment. Finally, it should be stressed that avulsions are not without consequences at the occlusal and periodontal level and can lead to the presence of dental resorptions.
