Les mésiopositions unilatérales maxillaires et mandibulaires : rappels et traitements

Abstract : Unilateral maxillary and mandibular mesial positioning result in a dental arch asymmetry and don’t have any aesthetic or skeletal impact. The aim of the treatment is to symmetrize the dental arches and to keep them in balanced position on the jaws. The two treatment options for the orthodontist are unilateral or asymmetric extractions and asymmetric distalisation devices that can be extraoral or intraoral and can be used on fixed appliance or with aligners. For several years, extraoral devices then intraoral devices with conventional anchorage were used for molar distalisation. They have proven to be effective for maxillary molars. However, they only allow distal tipping of mandibular molars. Furthermore, they induce anterior anchorage loss, unwanted dental tipping and extrusions. Skeletal anchorage devices, such as miniscrews, limit undesirable side movements and are free from patient cooperation. In some cases, these innovations help to reduce the indications for extractions. Moreover, among hyperdivergent patients, miniplates enable to combine ingression with molar distalisation. Knowledge of many of these appliances will allow the specialist to adapt his treatment plan to the clinical situation as best as possible.
