Use of fixed appliances in anterior crossbite correction

Abstract

Introduction: The prevalence of malocclusions is a problem that affects the infant from an early age. Anterior crossbite is an alteration in the sagittal plane that is reflected in an incorrect intermaxillary position with esthetic and functional repercussions. Objective: Correction of anterior crossbite in a 10 year old male patient using fixed appliances. Presentation of clinical case and treatment: A 10 year-old male patient was referred to the pediatric dentistry clinic at ENES UNAM Leon Unit for anterior crossbite intervention using maxillary orthopedics. The diagnosis was obtained from cephalometric studies (Jarabak, Steiner and Ricketts summarized) highlighting skeletal class I, short mandibular body, long mandibular ramus, position IS retrusion and position II protrusion. The upper and lower incisors were in bad position and molar class I with respect to the Angle classification. For the treatment "Hawley with bands" and "direct tracks" type plates were placed for the postural correction of the jaws, while the plates work on the expansion of the jaws looking for an alternative treatment. Results: We observed displacement of the mandible in a posterior position, decreasing the anterior crossbite, with wider lateralization movements and greater conformation of the arches preserving the molar class I . Conclusion: Interception with fixed appliances allows us to have a continuous progress and with greater perception of changes in a shorter term, proving its effectiveness and being a good alternative in patients with little cooperation.
