Abstract Class III skeletal malocclusion due to maxillary hypoplasia, compromises esthetics and functional aspects of patients. Different types of treatment have been developed depending on the severity of the deformity. Patients with severe maxillary hypoplasia and those with craniofacial abnormalities are normally treated with an ostegenic distraction after a Lefort I surgery. Mild to moderate skeletal class III patients are treated with facial mask combined with an intraoral device that usually produces dentoalveolar effects secondary to the maxillary protraction that sometimes are not desirable. Recently new methods of intraoral anchorage have been reported to be use with the traditional face mask, such as oseointegrated implants and miniplates. Also bimaxillary miniplates used with intermaxillary elastics can replace the extraoral appliance. These new approach has less or none dentoalveolar effects and therefore can be considered an ideal treatment option for a mixed dentition patient. The present review compares the effects, advantages and disadvantages of the different treatments available for class III skeletal malocclusion.
