Impacted canines may pose a functional and an esthetic problem for patients and can affect neighboring incisors. The aim of the study was to compare different treatment methods and their outcomes for impacted maxillary and mandibular canines.
The authors included 102 patients with 118 impacted canines (82 maxillary and 36 mandibular canines). Impacted canine were confirmed during clinical and radiologic examinations. Eighty-five patients (83%) with 97 impacted canines started the treatment. The authors analyzed treatment types and outcomes. Two maxillary and 4 mandibular canines were scheduled for extraction.
Orthodontic extrusion was used most frequently to treat impacted maxillary canines (89%), whereas orthodontic extrusion and transalveolar transplantation were performed most frequently in impacted mandibular canines (33% and 37.5%, respectively). The treatment was successful in 96% of the maxillary and 95% of the impacted mandibular canines.
Different methods were used for impacted maxillary and mandibular canines, but their overall success rate was high.
Successful outcome is determined via a well-planned and carefully executed orthodontic and surgical treatment. Early diagnosis is pivotal in facilitating spontaneous canine eruption and implementing transalveolar transplantation in a timely way.
阻生的尖牙可能会给患者带来功能和美观上的问题,并影响邻牙。本研究的目的是比较上颌和下颌阻生尖牙的不同治疗方法及其效果。
作者纳入了 102 名患有 118 颗阻生尖牙(82 颗上颌和 36 颗下颌)的患者。通过临床和影像学检查确认存在阻生尖牙。85 名患者(83%)的 97 颗阻生尖牙开始接受治疗。作者分析了治疗类型和结果。2 颗上颌和 4 颗下颌阻生尖牙被计划拔除。
上颌阻生尖牙最常采用正畸牵引(89%)治疗,而下颌阻生尖牙则最常采用正畸牵引和牙槽骨开窗导萌术(分别为 33%和 37.5%)治疗。上颌阻生尖牙的治疗成功率为 96%,下颌阻生尖牙的治疗成功率为 95%。
上颌和下颌阻生尖牙采用了不同的治疗方法,但总体成功率较高。
成功的结果取决于精心计划和执行的正畸和手术治疗。早期诊断对于促进尖牙的自然萌出和及时实施牙槽骨开窗导萌术至关重要。
