The present article reports the treatment of a 7-year-old girl with maxillary hypoplasia associated with multiple tooth agenesis through maxillary protraction with skeletal anchorage and pterygomaxillary separation. Two titanium mini-plates were placed in the lateral region of the nasal cavity and used as anchorage for maxillary protraction with a...

... an anteroposterior deficiency of the maxilla. The mandible was normal in size, as evidenced by the adequate length of the chin-neck line. There was no evident asymmetry and the lower third of the face was slightly diminished. Angle Class III malocclu- sion was observed, with anterior and posterior crossbite as well as multiple tooth agenesis (Fig. 1). The cephalometric analysis revealed a Class III skeletal pattern (ANB À4.38, Wits À8.2 mm) due to the maxillary deficiency (SNA 76.48, A-NPerp À2.7 mm), with a horizontal facial growth pattern (GoGn.Sn 31.48, FMA 20.98, Y-axis 538), and diminished lower facial third (ANS- Me 48.6 mm). The upper incisors were proclined (1.NA 27.58) and ...
