埋伏阻生牙好发于上颌前部,其中上切牙发病率有逐年增高趋势。埋伏阻生牙病因复杂,可能由遗传因素、系统因素和局部因素等共同导致。通过锥形束CT(CBCT)等影像学检查对埋伏阻生前牙进行准确定位是制定治疗方案的重要条件,外科手术暴露联合正畸牵引治疗是临床上最常用的治疗方法。文章对埋伏阻生切牙的发病情况、病因、临床检查和治疗方法等方面进行了阐述。
Buried impacted teeth occur in the maxillary anterior, including the incidence of incisors increased year by year trend. Burden impacted teeth cause complex, may be caused by genetic factors, systemic factors and local factors together. Accurate positioning of the impacted anterior teeth by imaging such as cone beam computed tomography (CBCT) is an important condition for the development of a therapeutic regimen. Surgical exposure combined with orthodontic traction is the most commonly used treatment in clinical practice. The article describes the incidence of impacted incisors, etiology, clinical examination and treatment methods and other aspects.
