RODRIGUEZ RIQUELME, Paul Esteban; ESTRADA VITORINO, Marco Antonio  y  MENESES LOPEZ, Abraham. Treatment of Class III malocclusion with maxillary protraction: Case Report. Rev. Estomatol. Herediana [online]. 2017, vol.27, n.3, pp.180-190. ISSN 1019-4355.  http://dx.doi.org/10.20453/reh.v27i3.3202.

Class III malocclusion is an anteroposterior skeletal problem in which altered relationships of the bones, teeth and muscular components can be observed; the skeletal component being most frequently altered in the sagittal and transverse maxillary deficiency. Early treatment of this anomaly is reported with a higher success rate. The protraction mask associated with a maxillary disjunction produces beneficial changes in the facial architecture. The patient’s age, collaboration and proper management of the system are the factors that lead to successful and stable results. The purpose of this report is to describe the treatment of a patient in the stage of the mixed dentition with the use of this device. Final considerations: The use of the Petit facial mask, associated with maxillary expansion, was useful in the correction of maxillary deficiency and class III malocclusion
