Abstract

Permanent maxillary canines are key teeth from both functional and aesthetic perspectives. Tooth transposition, a rare anomaly where two permanent teeth exchange positions within the same quadrant, poses significant diagnostic and therapeutic challenges. This study aimed to identify the clinical conditions guiding the decision to correct or maintain maxillary canine transposition through a narrative review of the literature, complemented by a detailed clinical case. Following PRISMA guidelines, a search of PubMed, ScienceDirect, Cochrane Library, EBSCO, and Scopus databases (2014-May 2024) yielded 19 relevant studies. This review found no consensus on treatment protocols, reinforcing the need for individualized decision-making based on patient characteristics, anatomical constraints, and clinician expertise. While orthodontic correction can yield favorable aesthetic outcomes, it requires meticulous planning and biomechanical control. Conservative approaches are often indicated in early-diagnosed or anatomically complex cases. The clinical case illustrates the complexity of managing the transposition, specifically of the maxillary canine into the central incisor position, emphasizing the importance of early diagnosis, digital planning, and a multidisciplinary approach for functional and aesthetic success.

摘要

从功能和美学角度来看，上颌恒尖牙都是关键牙齿。牙齿易位是一种罕见的异常情况，即同一象限内的两颗恒牙交换位置，这带来了重大的诊断和治疗挑战。本研究旨在通过文献叙述性综述并辅以详细临床病例，确定指导上颌尖牙易位矫治或维持决策的临床情况。按照PRISMA指南，检索了PubMed、ScienceDirect、Cochrane图书馆、EBSCO和Scopus数据库（2014年至2024年5月），共获得19项相关研究。本综述发现，在治疗方案上没有达成共识，这进一步凸显了基于患者特征、解剖限制和临床医生专业知识进行个体化决策的必要性。虽然正畸矫治可以产生良好的美学效果，但需要精心规划和生物力学控制。对于早期诊断或解剖结构复杂的病例，通常采用保守方法。该临床病例说明了处理易位，特别是上颌尖牙易位至中切牙位置的复杂性，强调了早期诊断、数字化规划以及多学科方法对于实现功能和美学成功的重要性。
