RODRIGUEZ GONZALEZ, Leobel; DELGADO CARRERA, Lucia  e  RODRIGUEZ, Maiyelín. Treatment of anteroposterior maxillary hypoplasia. Medicentro Electrónica [online]. 2020, vol.24, n.1, pp. 207-216. ISSN 1029-3043.

Patients with anteroposterior hypoplasia of the upper jaw should be detected during early dental care, that is, when they are still growing, in order to be able to induce alveolar, skeletal and aesthetic changes. The patient was 12 years old, had residual growth potential and presented skeletal Class III Syndrome due to retrusion of the upper jaw. She was characterized by a normal sized jaw and an anterior crossbite; a Petit orthopedic face mask was used as a treatment for anterior maxillary traction and a Hyrax screw for dentoalveolar expansion. These instruments were used in order to correct the simple posterior crossbite on the left side. Satisfactory results were observed from the skeletal, occlusal, facial and profile points of view.

Palavras-chave : malocclusion, angle class III/ therapy; extraoral traction appliances.
