La corrección de las discrepancias dentofaciales puede llevarse a cabo mediante diversos tratamientos como son la ortodoncia convencional compensatoria, la cirugía ortognática y recientemente la distracción osteogénica. Una de las discrepancias dentofaciales que causan controversia para su tratamiento, por la decisión de realizar o no extracciones de órganos dentarios, es la deficiencia maxilomandibular transversa. Estudios realizados en 1991 por Proffit y Little han demostrado que existe un alto índice de recidiva en tratamientos ortodónticos compensatorios, lo que provoca inestabilidad oclusal en el postoperatorio, incrementando así el índice de recidiva. Se presenta el caso clínico de un paciente femenino de 19 años con un diagnóstico de deficiencia maxilar transversa y clase II esqueletal, tratado mediante distracción osteogénica con un aparato Hyrax intraoral dentosoportado, con el fin de mejorar la armonía de la arcada superior, evitando la extracción de órganos dentarios y mejorando la estabilidad oclusal para ser sometida a cirugía ortognática.
Palabras clave: Discrepancia dentofacial; distracción osteogénica; Hyrax
Treatment of dentofacial deformities could be done by conventional orthodontics, orthognatic surgery and recently by osteogenetic distraction. The treatment of transversal maxillary or mandibular deficiency is the most controversial among the dentofacial deformities because of the decision to extract or not healthy teeth. The studies carried out by Proffit and Little in 1991 had shown an increased rate of failure in orthodontic compensatory treatments due to occlusal instability. A case of a 19-year-old patient with transverse maxillary deficiency and Class II profile is presented. The treatment was carried out by means of osteoge-nic distraction with an intraoral tooth-supported Hyrax appliance, with the purpose of increasing the maxillary width, avoiding teeth extraction and improving occlusal stability for orthognatic surgery.
Key words: Dentofacial deformity; osteogenic distraction; Hyrax
