Abstract

Transposition of teeth is a rare condition, with a prevalence of 0.3-0.4% in general population. They are more commonly observed in females, and may occur unilaterally/bilaterally with greater frequency of left side occurrence in unilateral transposition cases. A 17-year-old female patient reported with the chief complaint of unaesthetic smile. On clinical examination the patient was diagnosed with Angle's class I malocclusion with an ectopically erupted maxillary left canine labial to the left central incisor with retained deciduous canine. The treatment plan decided was to extract the retained deciduous canine, level and align the ectopic canine using an R-loop. The treatment for the patient was finished in 14 months and was retained using a fixed lingual retainer in the upper and lower arches.

摘要

牙齿易位是一种罕见的情况，在普通人群中的患病率为0.3%-0.4%。女性中更常见，可单侧/双侧发生，单侧易位病例中左侧发生的频率更高。一名17岁女性患者以笑容不美观为主诉前来就诊。临床检查发现该患者被诊断为安氏I类错牙合，上颌左侧尖牙异位萌出至左侧中切牙唇侧，乳牙尖牙滞留。决定的治疗方案是拔除滞留的乳牙尖牙，使用R形曲排齐并整平异位尖牙。该患者的治疗在14个月内完成，并在上、下牙弓使用固定舌侧保持器进行保持。
