The preferred management for children having skeletal Class III malocclusion with retruded maxilla and/or prognathic mandible is the use of devices that encourage the growth and anterior movement of the maxilla bone and/or restrict the exessive mandible growth. The orthopedic treatment consisting of a face mask with rapid maxillary expansion (RME) produces the most dramatic results in the shortest period of time. The purpose of this article is to review a quick correction of skeletal class III maloclussion in the primary dentition through a case example with use of a face mask plus rapid maxillary expansion therapy in a 5 year-old male patient due to a combination of retruded maxilla and protruded mandible, in primary dentition, who was treated with a Petit face mask in conjunction with a bonded RME intraoral appliance added with bite blocks. The first evident occlusal outcomes were a clockwise rotation of the mandible, a positive overjet of 3 mm, a correct overbite, a canine Class I relationship, and a bilateral flush terminal plane. After discussing the present clinical case report and the related published literature, we concluded that skeletal class III malocclusions should be treated as soon as the first clinical signs of abnormal craniofacial growth are recognized, during the first years of life.]]></p></abstract>
<abstract abstract-type="short" xml:lang="es"><p><![CDATA[Resumen La clase III esquelética es una maloclusión caracterizada por mordida cruzada anterior como resultado de una discrepancia esquelética de la base maxilar y mandibular, que implica desarmonía craneofacial y del perfil. El tratamiento de elección para niños con maloclusión clase III esquelética con mandíbula maxilar y/o prognática es el uso de dispositivos que estimulan el crecimiento y el movimiento anterior del hueso maxilar y/o restringen el crecimiento excesivo de la mandíbula. El tratamiento ortopédico que consiste en una máscara facial con expansión maxilar rápida (EMR) produce resultados en un período de tiempo más corto. El propósito de este artículo es revisar una corrección rápida de la maloclusión de clase III esquelética en la dentición primaria mediante el uso de una máscara facial más terapia de expansión maxilar rápida en un paciente masculino de 5 años debido a una combinación de maxilar retruido y mandíbula prominente, en dentición primaria, que fue tratada con una mascarilla Petit junto con un dispositivo intraoral unido con bloques de mordida. Los primeros resultados evidentes fueron una rotación en sentido horario de la mandíbula, un overjet positivo de 3 mm, una sobremordida correcta, una relación canina de Clase I y un plano terminal de descarga bilateral. Después de discutir el presente informe de caso clínico y la literatura publicada relacionada, concluimos que las maloclusiones de clase III esqueléticas deberían tratarse tan pronto como se reconozcan los primeros signos clínicos de crecimiento craneofacial anormal, durante los primeros años de vida.]]></p></abstract>
