Correction of Anterior Crossbite in Mixed Dentition- A Case Series

Abstract

Anterior crossbite is a common developing malocclusion in mixed dentition that may result in abnormal occlusal function, tooth wear, periodontal complications, and altered mandibular function if left untreated. Early interceptive correction can restore normal incisor relationships and reduce the complexity of subsequent orthodontic treatment. This case series presents five mixed-dentition patients with dental anterior crossbite managed using different interceptive approaches. Treatment modalities included a Hawley appliance with Z-spring and posterior bite plane, 2 × 4 appliance, anterior sectional twin-bracket appliance, modified 2 × 2 utility arch, and an Essix appliance. Treatment selection was individualized according to the number of teeth involved, eruption status, available arch space, and anticipated patient cooperation. All patients demonstrated adequate space for correction based on mixed-dentition analysis. Thus, We have found that, early diagnosis and individualized appliance selection can provide effective correction of anterior crossbite during mixed dentition. Both removable and limited fixed appliances demonstrated satisfactory clinical outcomes when appropriately selected and monitored.
