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.
前牙反颌是一种上颌前牙排列不齐的情况，即咬合位于下颌前牙的后方，是混合牙列中常见的牙齿问题。本病例系列研究了三种正畸矫治器，即卡特兰矫治器、可摘指簧矫治器和2×4矫治器，用于治疗前牙反颌的临床效果。第一个病例研究涉及一名患有单牙反颌的7岁患者。该患者使用2×4矫治器进行治疗，在合理的治疗时间内问题得到了满意的矫正。治疗过程对患者来说很舒适，患者满意度很高。第二个病例涉及一名9岁患者，其两颗恒中切牙均出现反颌。该患者使用卡特兰矫治器进行治疗，治疗时间最短，但不适感最强。第三个病例研究聚焦于一名患有单牙反颌的9岁患者。这种情况可能由牙齿或骨骼差异引起，如果不加以治疗，可能会导致牙周损伤、异常的牙釉质侵蚀和颞下颌关节紊乱。使用各种矫治器进行及时干预对于矫正反颌和避免潜在后果至关重要。本研究独特地比较了设计和应用各不相同的卡特兰矫治器、可摘指簧矫治器和2×4矫治器，并评估了一系列结果指标，包括治疗时间、咬合改善情况、患者舒适度和不良反应。所有三种矫治器，如卡特兰矫治器、可摘指簧矫治器和2×4矫治器，在矫正前牙反颌方面都是有效的，表明多种治疗选择都可以取得成功的结果。
