Abstract
Anterior crossbite is an abnormal sagittal relationship in which the upper incisors occlude lingually to the lower incisors, potentially leading to functional and esthetic impairments if left untreated. Timely diagnosis and early intervention during the mixed dentition phase are essential to prevent the development of more complex malocclusions, as well as to maintain proper occlusal relationships and facial harmony. This case report aims to provide practical guidance for general and pediatric dentists regarding the diagnosis and management of anterior crossbite, emphasizing the importance and effectiveness of interceptive orthodontic approaches. An eight-year-old patient presented with an anterior crossbite affecting the maxillary incisors, associated with a Class I skeletal relationship and no significant transverse discrepancy. Comprehensive clinical and radiographic evaluations confirmed the presence of an anterior dental crossbite. The chosen treatment consisted of a removable orthodontic appliance with an expansion screw, designed to promote labial movement of the maxillary incisors. This therapeutic approach proved to be effective, resulting in the correction of the crossbite, with adequate overbite and overjet achieved within a period of 6 months of follow-up. The patient demonstrated good compliance, and no adverse effects on periodontal or supporting tissues were observed. Early interceptive management during the mixed dentition stage can successfully restore normal occlusal function, enhance facial esthetics, and minimize the risk of unfavorable skeletal growth. When properly indicated and executed, such treatment can be effectively carried out by general and pediatric dentists, potentially reducing the need for more complex and invasive orthodontic procedures in the future.
