摘要
目的:分析8颗前磨牙先天缺失患者的临床表现及序列治疗,为该类患者的诊治提供一定参考。方法:收集29例8颗前磨牙先天缺失的病例,记录患者的缺失牙数目、牙位及现存牙畸形,查询每位患者电子病历中家族史、既往史和治疗史,分析患者的资料。结果:本研究组病例缺牙数目最多的为8颗,有13例,占44.83%,最常见的缺牙模式为第一前磨牙、第二前磨牙联合缺失,每个象限TAC值集中在31及以下。本组病例还伴有上颌侧切过小牙、牙齿发育迟缓、乳磨牙固连。结论:8颗前磨牙先天缺失的病例临床上罕见,有多种缺牙模式,诊治复杂、周期长,应根据个体差异制定个性化的、多学科合作的序列治疗。
Objective:To analyze the clinical characteristics and sequential treatment for patients with congenital absence of eight premolars,and to provide some reference for the diagnosis and treatment of such patients.Methods:A total of 29 subjects of 8 premolars congenital absence were collected.The number and position of absence teeth,and existing dental development anomalies were recorded.Family history,past history and treatment history of each subject in the electronic medical records were inquired,and data were analyzed.Results:In our study group,the largest number of oligodontia was 8,with 13 subjects,accounting for 44.83%.The most common tooth agenesis pattern was agenesis of the combined first and second premolars.TAC values in each quadrant were concentrated at 31 and below.The subjects were accompanied by microdontia of the maxillary lateral incisors,delayed teeth development,and tooth ankylosis of deciduous molar.Conclusion:Clinically,congenital absence of eight premolars is rare and there are multiple tooth agenesis patterns.The diagnosis and treatment are complexed and treatment period is long,so it is necessary to develop individualized and multidisciplinary sequential therapy according to individual differences.
