Comparative Clinical Outcomes in the Treatment of Anterior Crossbite Using Three Different Appliances: A Case Series.

Anterior crossbite, a misalignment of the upper front teeth in which the bite is behind the lower front teeth, is a common dental condition in mixed dentition. This case series examines the clinical results of three orthodontic appliances, namely Catlan's appliance, the removable finger-spring appliance, and the 2x4 appliance, in the management of anterior crossbite. The first case study involves a seven-year-old patient with a single-tooth crossbite. The patient was treated using a 2x4 appliance, which resulted in a satisfactory correction of the problem within a reasonable treatment duration. The therapy was comfortable for the patient and resulted in high patient satisfaction levels. The second case involves a nine-year-old patient with a crossbite on both of their permanent central incisors. The patient was treated using a Catlan's appliance, which had the shortest treatment duration but resulted in the highest level of discomfort. The third case study focuses on a nine-year-old patient with a single-tooth crossbite. The condition can arise from dental or skeletal disparities and, if not managed, can cause periodontal damage, aberrant enamel erosion, and temporomandibular joint disorders. Prompt intervention using various appliances is essential for rectifying the crossbite and averting potential consequences. This study uniquely compares Catlan's appliance, the removable finger-spring appliance, and the 2x4 appliance, each distinct in design and application, and evaluates a range of outcome measures, including treatment duration, occlusal improvement, patient comfort, and adverse effects. All three appliances, such as Catlan's appliance, the removable finger-spring appliance, and the 2x4 appliance, are effective in correcting anterior crossbite, demonstrating that multiple treatment options can achieve successful outcomes.
