Treatment of Class II malocclusion with anterior open bite and posterior crossbite with the aid of mini‐implants in a patient with Down syndrome: Clinical case report

Abstract

AbstractObjectiveWe report the orthodontic treatment of a class II malocclusion with anterior open bite and posterior crossbite in a patient with Down syndrome (DS) treated with mini‐implants.MethodsTreatment began with rapid maxillary expansion with a Haas appliance, followed by dental alignment and leveling with a fixed appliance and the correction of class II dental relationships with the use of orthodontic mini‐implants associated with a sliding jig.ResultsThe results obtained at the end of the treatment were satisfactory, with improvements in occlusion, including bite closure; maxillary expansion; and the correction of dental relationships.ConclusionWhen well‐planned, orthodontic treatment in a patient with DS achieves satisfactory results from a skeletal, occlusal, and facial perspective.
