摘要


牙齒錯位乃指在牙弓上的同一象限中,兩顆牙齒萌出時位置互換的現象。犬齒錯位又是在口腔內最常見的牙齒錯位,主要發生在上顎犬齒及第一小臼齒處,其發生率約為0.135~0.51%。雖然犬齒錯位的機制尚未有定論,但推測與遺傳、乳犬齒的延遲脫落以及外傷有關。本報告針對犬齒錯位的分類、發生率、病因學以及治療計畫的擬定作一整體的論述,藉此希望對於臨床牙醫師在治療這類病患時有所幫助。

Transposition is described as an interchange in the position of two teeth within the same quadrant of the dental arch. Canine transposition is reportedly the most common transposition in human dentition. The incidence of maxillary canine-premolar transposition is reported to be 0.135-0.510%. Although the exact mechanism of canine transposition is unclear, it seems to be closely related to genetically influenced, retained deciduous canine, and a history of trauma. In this article, we focus on the classification, incidence, etiology, and treatment modalities of tooth transposition. We hope this information will help clinicians treating patients with this kind of dental anomaly.
