With the exception of the maxillary and mandibular third molars, the maxillary canine is the most commonly encountered impaction. In North America, palatally located impactions appear to predominate over labially impacted canines and occur more frequently in women. Because of the common nature of this phenomenon, the general dentist should know how to properly diagnose and manage potential disturbances in the eruption of the maxillary canine. If diagnosed early, and when clinically and radiographically indicated, extraction of the deciduous canine may help correct the eruption path of the permanent tooth and prevent impaction. This article reviews the etiology, prevention, and surgical and orthodontic management of impacted cuspids. Because the general dentist is often the first dental care provider to come in contact with patients with impacted canines, knowledge about this common dental anomaly is essential to provide proper comprehensive therapy.
除上颌和下颌第三磨牙外，上颌尖牙是最常见的阻生牙。在北美，腭侧阻生似乎比唇侧阻生更为常见，且在女性中发生率更高。由于这种现象很常见，普通牙医应了解如何正确诊断和处理上颌尖牙萌出过程中可能出现的问题。如果早期诊断，并在临床和影像学检查有指征时，拔除乳牙可能有助于纠正恒牙的萌出道，防止阻生。本文综述了阻生尖牙的病因、预防以及外科和正畸治疗。由于普通牙医通常是最早接触到阻生尖牙患者的牙科保健提供者，了解这种常见的牙齿异常情况对于提供适当的综合治疗至关重要。
