Clinical aspects of Angle class II/1 malocclusion during the eruption of the 12-year-old molar

Abstract

Introductions. The vicious habit of sucking the thumb is an etiological factor of Angle Class II/1 malocclusion. Case presentation. In the clinical case that we intend to present, the main goal of the treatment was to recover the occlusion and the functions of the dento-maxillary complex. The treatment relied on the use of a fixed appliance. The sagittal inocclusion was thus reduced and the parameters of occlusion were brought to normality. Conclusions. We consider that the period of orthodontic treatment was reduced because the climax of the bones growth took place at the same time with the eruption of the 12-year-old molars.
