Paciente femenino de 20 años de edad que acude a la Clínica de Ortodoncia de la División de Estudios de Posgrado e Investigación de la Universidad Nacional Autónoma de México. Su motivo principal de consulta es: «Cuando me quitaron las muelas del juicio me dijeron que me podían operar pero primero tenían que ponerme brackets»; esto para poder corregir la disarmonía dentofacial que presentaba. A la exploración clínica extraoral, se observa una cara mesoprosopa con labios competentes; verticalmente presenta el tercio inferior aumentado. Su perfil es convexo con una proyección deficiente del mentón. Intraoralmente, presenta apiñamiento dental superior e inferior, relación clase II molar y canina, la sobremordida vertical y horizontal considerablemente aumentadas y líneas medias no coincidentes. Su diagnóstico cefalométrico mostró clase II esquelética por protusión maxilar. El tratamiento propuesto ortodóncico-quirúrgico, en tres fases: ortodóncica prequirúrgica, quirúrgica y ortodóncica posquirúrgica. En la fase prequirúrgica se descompensó a la paciente para prepararla para la cirugía. En la fase quirúrgica se realizó una osteotomía sagital mandibular para realizar un movimiento de avance en combinación con una mentoplastia de avance. Durante la fase posquirúrgica se lograron relaciones oclusales ideales en cuanto a las clases caninas, sobremordida, resalte, coincidencia de líneas medias y el detallado final del caso. Con el tratamiento mejoró la oclusión y la armonía facial de la paciente.</p></div><div><p>The objective of this case report was to show the correction of a class II division 1 malocclusion in an adult patient. A female patient of 20 years of age attended the Orthodontics Clinic of the Division of Pos-Graduate Studies and Research of the Odontology Faculty at the National Autonomous University of Mexico. Her main reason for consultation was: «When I removed the wisdom teeth I was told that I could have orthognathic surgery but first I needed braces»; this in order to correct the dento-facial disharmony. Upon facial clinical examination, the patient presented a mesofacial biotype with competent lips; vertically she presented an increasedlower third. Her profile was convex with deficient chinprojection. Intraorally, the patient exhibited upper and lower crowding, molar and canineClass II, considerably increased overbite and overjet as well as noncoincident dental midlines. The cephalometric diagnosis showed a skeletal Class II due to maxillary protrusion. It was suggested an orthodontic-surgical treatment in three phases: pre-surgical, surgical and pos-surgical. In the pre-surgical phase the patient was decompensated in order to prepare her for surgery. During the surgical phase, mandibular sagittal osteotomies were performed to advance the mandible in combination with an advancement genioplasty.
