Reporte de caso(Universidad Católica de Cuenca., 2023) Altamirano Arias, Doménica Cristina; Lima Illescas, Miriam Verónica; 0106973217Objective: To report the post-treatment dento-skeletal changes in pediatric patients with skeletal Class III malocclusion. Case report: Treatment in a pediatric patient with skeletal Class III malocclusion consisted of the placement of a Hyrax-type fixed appliance to achieve maxillary expansion in conjunction with the Petit face mask, which helped to protract the maxilla. The dento-skeletal changes were evidenced after six months, resulting in an increase of 1.3° in the anteroposterior maxillomandibular relationship (ANB), initial ANB 0.2°, as well as the anteroposterior position of the maxilla to the cranial base (SNA) increased to 73.9° (initial SNA 72.7°), while the anteroposterior position of the mandible concerning the anterior cranial base (SNB) was maintained. Among dental changes in the case report, there was evidence in the three spatial planes of the sagittal plane: a bilateral canine class in neutroclusion, a 1 mm protrusion, and bilateral molar neutroclusion. The anterior area was preserved in the transverse plane with normal bilateral occlusion. Finally, in the vertical plane, it increased by 1 mm in the overjet. Conclusions: The reported changes were achieved by applying fixed and removable appliances, considered one of the most promising therapeutic approaches to treat Class III malocclusions in early mixed dentition.
