Single-tooth anterior dental crossbite is a commonly observed malocclusion in the mixed dentition of children. Early intervention is crucial since malocclusion does not correct itself and can contribute to enamel wear, periodontal disease, and disturbances in temporomandibular joint function. Several treatment methods have been proposed to correct it, including removable appliances and uncomplicated interceptive techniques. This case report shows three pediatric patients diagnosed with single-tooth anterior crossbite. In one case, the crossbite was successfully treated with a Hawley's appliance featuring a Z-spring and a posterior bite plane in just a few weeks. In the remaining two cases, tongue blade therapy was used as a minimally invasive treatment. In one case, crossbite correction was achieved following the performance of a diode laser-assisted frenectomy, which was necessary because a thick labial frenum was obstructing the proper alignment of the teeth.
单颗前牙反牙合是儿童混合牙列中常见的错牙合畸形。早期干预至关重要，因为错牙合畸形不会自行纠正，且可能导致牙釉质磨损、牙周疾病以及颞下颌关节功能紊乱。已经提出了几种治疗方法来纠正它，包括可摘矫治器和简单的阻断性技术。本病例报告展示了三名被诊断为单颗前牙反牙合的儿科患者。在一个病例中，仅用了几周时间，通过带有Z形弹簧和后牙咬合平面的霍利矫治器成功治疗了反牙合。在其余两个病例中，使用舌板疗法作为微创治疗。在一个病例中，由于厚的唇系带阻碍牙齿正常排列，在进行二极管激光辅助系带切除术之后实现了反牙合的矫正。
