Impacted teeth present many problems for the orthodontist. They can compromise tooth movement, esthetics, and functional outcomes. The second most commonly impacted tooth, after the maxillary third molar, is the maxillary canine, with an incidence from 1% to 2.5%. Maxillary canines can be impacted facially or palatally and are more common in female patients than in male patients. Therefore, the purpose of this paper is to address the incidence and etiology associated with impacted maxillary canines, the clinical and radiographic evaluation of the situation, and the techniques for managing this problem. Papers related to this topic were identified and reviewed thoroughly. A decision tree involving the various techniques employed to expose impacted canines is presented, together with methods used to identify the location of impacted canines. The impacted canine can be properly managed with proper diagnosis and technique.
阻生牙给正畸医生带来了许多问题。它们会影响牙齿移动、美观和功能效果。在上颌第三磨牙之后,第二常见的阻生牙是上颌尖牙,发生率为1%至2.5%。上颌尖牙可颊侧或腭侧阻生,在女性患者中比男性患者更常见。因此,本文的目的是探讨与上颌尖牙阻生相关的发生率和病因、该情况的临床和影像学评估以及处理此问题的技术。识别并彻底回顾了与该主题相关的论文。给出了一个涉及用于暴露阻生尖牙的各种技术的决策树,以及用于确定阻生尖牙位置的方法。通过正确的诊断和技术,可以妥善处理阻生尖牙。
