Clinical Management of Dewey’s Type 3 Anterior Crossbite in Angle Class I Malocclusion: A Case Report

Anterior crossbite is a significant malocclusion characterized by the lingual eruption of one or more maxillary front teeth, often impeded by the mandibular deciduous counterparts. This clinical case study focused on a patient with an anterior crossbite involving the central and lateral incisors, detailing the diagnosis, treatment course, and outcomes. During the clinical evaluation, both aesthetic concerns related to attrition and occlusal malocclusion were identified. Diagnostic tests, including radiographs and extraoral and intraoral examinations, were conducted before initiating treatment. The treatment aimed to correct the anterior crossbite while enhancing function and aesthetics. Fixed orthodontic appliances were introduced to facilitate precise tooth movement. Throughout the first year, the alignment, crossbite correction, and occlusal refinement were meticulously documented through photographs. The treatment resulted in improved occlusal relationships, functional bite, and enhanced smile aesthetics. This case report underscores the importance of comprehensive and functional orthodontic treatment in effectively resolving anterior crossbite and providing optimal patient care.
