Tooth transpositions present at a relatively low incidence in the world population and primarily affect maxillary canines and premolars. Treatment of this disturbance should take into account aspects such as facial pattern, age, malocclusion, tooth-size discrepancy, stage of eruption, and magnitude of the transposition. Mechanics for correction should be entirely individualized, reducing the risks and adverse effects. Practitioners often select simpler options, indicating extraction of permanent teeth, which is an irreversible procedure that may bring about damages to the patient. This study presents a case report and treatment of unilateral transposition of maxillary canine and premolar with repositioning of affected teeth to their respective normal positions.
牙齿换位在世界人口中的发病率相对较低，主要影响上颌尖牙和前磨牙。这种牙列紊乱的治疗应考虑面部形态、年龄、错牙合、牙大小差异、萌出阶段以及换位程度等方面。矫正力学应完全个体化，以降低风险和不良反应。从业者通常会选择更简单的方法，如拔除恒牙，这是一种不可逆的程序，可能会给患者带来损害。本研究报告了一例上颌尖牙和前磨牙单侧换位的病例及治疗情况，即将患牙重新定位到各自的正常位置。
