RESUMEN

Se reporta un caso de un paciente masculino de 19 años 3 meses, cuyo motivo de consulta fue «tener molestias en la mandíbula». Es clase III esquelética, hiperdivergente, clase III molar bilateral, clase III canina bilateral, con los incisivos superiores proclinados, la mordida cruzada anterior y posterior bilateral, tiene apiñamiento superior e inferior, con la línea media dental inferior desviada, presenta colapso maxilar, el tercer molar inferior izquiero en formación, el paciente no refiere ningún hábito. El tratamiento se realizó en tres fases, fase prequirúrgica: alineación, nivelación, descompensación dental, tripodismo (estabilidad oclusal), expansión transversal. Fase quirúrgica: cirugía mandibular Le Fort I: avance: 5 mm, Fase postquirúrgica: detallado y retención. Tiempo de tratamiento activo 4 años 4 meses. Se utilizaron retenedores removibles Hawley superior e inferior y fijos de caninos a caninos tanto en superior como en inferior. El resultado del tratamiento fue exitoso, con la obtención de clases I caninas y molares bilaterales, sobremordida horizontal y vertical adecuadas, líneas medias coincidentes, correcta intercuspidación y un perfil facial armónico. Tiempo de 4 años y 4 meses.
