Dilemas contemp. educ. política valores [online]. 2021, vol.8, n.spe4, 00064. Epub 20-Sep-2021. ISSN 2007-7890. https://doi.org/10.46377/dilemas.v8i.2819.
Class III skeletal malformations generally present a concave profile, maxillary retrusion, and protrusion. Maxillary protrusion in combination with rapid expansion of the maxilla is a very well used treatment in patients with maxillary deficiency. The objective of this work is to demonstrate through clinical cases, the treatment of this skeletal anomaly with the use of the Petit Mask seen in 3 patients between 3 to 8 years old who presented concave profile with maxillary deficiency and anterior crossbite; A modified Hass type circuit breaker with hooks is placed at the level of the canines and the circuit breaker is immobilized, and the Petit Mask is installed; finally, the patients presented correction of the skeletal problem.
