The purpose of this case report is to present the management of an impacted maxillary canine adjacent to a deviated palatal first premolar root.
Maxillary canine impactions are of multifactorial etiology. The incidence of maxillary canine impaction ranges from 1% to 3%. One of the reasons for canine impaction might be a deviated palatal premolar root. To date, a total of six cases have been described where impacted maxillary canines were found in close proximity to a deviated palatal first premolar root.
A male patient, aged 17 years 3 months, with a Class I molar relationship was referred for the continuation of orthodontic therapy. Leveling was completed in the lower and upper arches. Although sufficient space was available in the upper arch the left canine had not erupted. Radiographic examination disclosed a deviated palatal root of the first premolar in the canine eruption path.
A multidisciplinary treatment approach for the maxillary impacted canine adjacent to a deviated palatal premolar root is described. The premolar was endodontically treated and the deviated root surgically resected. The impacted canine was then orthodontically erupted into position.
A deviated maxillary premolar root may cause canine impaction. A multidisciplinary approach facilitates successful treatment results in such cases.
本病例报告旨在介绍对一颗紧邻腭侧第一前磨牙牙根偏斜的上颌阻生尖牙的处理。
上颌尖牙阻生病因多方面。上颌尖牙阻生的发生率为1%至3%。尖牙阻生的原因之一可能是腭侧前磨牙牙根偏斜。迄今为止，共描述了6例上颌阻生尖牙紧邻腭侧第一前磨牙牙根偏斜的病例。
一名17岁3个月的男性患者，磨牙关系为Ⅰ类，因继续正畸治疗前来就诊。上下牙弓排平已完成。尽管上颌牙弓有足够间隙，但左侧尖牙未萌出。影像学检查显示在尖牙萌出道中有一颗腭侧第一前磨牙牙根偏斜。
描述了一种针对紧邻腭侧前磨牙牙根偏斜的上颌阻生尖牙的多学科治疗方法。对前磨牙进行了根管治疗，并手术切除了偏斜的牙根。然后通过正畸方法将阻生尖牙牵引至合适位置。
上颌前磨牙牙根偏斜可能导致尖牙阻生。多学科方法有助于在此类病例中取得成功的治疗效果。
