Facemask therapy with rigid anchorage in a patient with maxillary hypoplasia and severe oligodontia

Am J Orthod Dentofacial Orthop. 2003 May;123(5):571-7. doi: 10.1067/mod.2003.S0889540603000520.


In this report, we describe the treatment of a 10-year-old girl with a Class III skeletal relationship with maxillary hypoplasia and severe oligodontia. The maxillary arch was in a complete crossbite relationship with the mandibular arch. The treatment plan called for displacing the maxillary complex anteriorly with a facemask. Because of the lack of available teeth, a rigid anchorage implant was used in combination with the remaining teeth to provide anchorage. A titanium lag screw was placed in the maxillary alveolus. Three weeks later, 800 g of orthodontic force was applied. A significant anterior displacement of the nasomaxillary complex was achieved with the facemask. At the end of treatment, a temporary removable partial denture was placed.
