Corrección de mordida cruzada anterior con ortopedia

Abstract

RESUMENLa mordida cruzada anterior es común en pacientes en crecimiento; dentro de su etiología tenemos: trauma a los incisivos primarios con desplazamiento del brote del diente permanente, exfoliación de los incisivos primarios con la desviación a palatino del incisivo permanente ocasionando el colapso de la premaxila, dientes anteriores supernumerarios y perímetro de arco deficiente.ObjetivosCorrección de la mordida cruzada anterior e incrementar el perímetro del arco maxilar.Presentación del casoPaciente masculino de 11 años de edad referido a la clínica de ortodoncia de DEPeI con mordida cruzada anterior y con la avulsión dentaria de un mesiodens por un traumatismo. El diagnóstico fue: leptoprosopo, clase I esquéletica, crecimiento horizontal mandibular, clase I molar y biretroclinación dental.Tratamientoprimera fase ortopédica y segunda fase ortodóncica: Se construyó un dispositivo tipo bite-block y tornillo sagital combinado con una máscara facial.ResultadosLa mordida cruzada anterior fue eliminada. En relación con los análisis de Steiner, Jarabak y Ricketts, los parámetros para el análisis esqueletal fueron: ángulo SNA donde se observó un incremento de 4°, en el caso de la convexidad se registró un incremento de 3mm y un aumento de 1° en el caso del ángulo SNB. En relación con los parámetros dentales se obtuvo una disminución de 1° en el ángulo interincisal y un aumento de 8° en el ángulo SN/1 sup. los tejidos blandos se modificaron favoreciendo el perfil.ABSTRACTAnterior cross-bites are common in growing patients due to different etiological factors such as: injury to the primary incisors with displacement of the permanent teeth; exfoliation of permanent incisors and palatal deviation because of a collapse in the premaxilla; supernumerary teeth and arch length deficiency.ObjectivesTo present a case of an anterior crossbite orthopaedic correction.Case reportAn 11-year-old male patient was referred to the Orthodontics Clinic with an anterior crossbite and dental avulsion of a mesiodens due to trauma. The patient presented a dolichofacial pattern, a skeletal Class I relationship, horizontal mandibular growth, Class I molar relationship and retrusive maxillary and mandibular incisors.TreatmentFirst phase: Orthopaedics. Second phase: Orthodontics. An appliance similar to the Bite Block with a hyrax expansion screw placed parallel to the mid-palatal suture and a facial mask were constructed.ResultsThe patient's anterior crossbite was corrected. Maxillary parameters were evaluated in relation to the Steiner, Jarabak and Ricketts analysis; SNA angle was increased by 4°, the convexity increased by 3mm and the SNB angle, by 1°. Dental parameters showed that the interincisal angle decreased by 1° whereas SN/1 sup angle was increased by 8°. The patient's soft tissues showed a positive change, which favoured the profile.
