RESUMO
This current study aims at cephalometrically evaluating the skeletal,dental, and soft tissues sagittal and vertical alterations in patients who underwent surgically assisted rapid maxilla expansion. The sample comprised 17 teleradiographs in lateral norm of 17 Brazilian adult subjects, being 6 male subjects and 11 female subjects, with average age of 24 years and 1 month, presenting a severe transverse deficiency of the maxilla. Teleradiographs were taken at the beginning of treatment (T1), after SARME (T2), and after three months in retention with the disjunctive appliance (T3). According to the analysis and discussion of the results achieved, it was seen a clock-wise rotation of both the maxilla and mandible, presenting, as consequence, an increase of the AFAI. After three months in retention therapy, there was a relapse of this behavior. It was also seen an extrusion of the upper incisors, in which was kept during the retention period. During retention, there was also a retrusion of the upper incisors. As for the upper molars, there was an extrusion after expansion, followed by a minor relapse when compared to the effect of the expansion achieved. There was no alteration of the soft tissues regarding the nasal thickness. And, there was a retrusion of the upper and lower lips, and the soft pogonion, following the skeletal part. There was an increase of the nasolabial angle.
