目的了解正畸联合自体牙移植术对前牙埋伏阻生的临床疗效评价其临床的作用效果。方法对某院就诊的22例患者行自体牙移植术,年龄在7～18岁,平均12.5岁;其各自牙齿阻生部位不同,尖牙阻生10例,中切牙阻生6例,侧切牙阻生4例,多个牙埋伏阻生2例;对这些患者矫治时间在11～25个月,平均18个月[1];应用X线及三维CT对埋伏牙进行定位,患者均先行正畸治疗之后行自体牙移植手术,用钢丝或其他固定措施固定;待自体牙移植成功后进行进一步正畸治疗。结果 22例患者术后随访1.5～4年,患者术后移植牙均稳固于牙列中,牙龈形态基本良好;抽取随访患者进行X线片观察显示移植牙牙根并无吸收现象。结论正畸联合自体牙移植治疗前牙埋伏阻生,能有效恢复牙弓外形及口腔功能,还可增进美观[2],在今后的医学发展道路上可作为一种有效可行的治疗前牙埋伏阻生的方法在临床上推广使用。
Objective To understand the clinical effect of orthodontic combined with autologous dental grafting on impacted obstruction of anterior teeth. Methods Twenty-two patients treated in a hospital underwent autologous dental transplantation, aged from 7 to 18 years old, with an average of 12.5 years old. There were different impacted parts of their teeth, including 10 cases of incisors, 6 cases of incisors, 6 cases of lateral incisors Tooth occlusion in 4 cases, multiple teeth impacted in 2 cases; correction of these patients in 11 to 25 months, an average of 18 months [1]; X-ray and three-dimensional CT of the ambush to locate the teeth, the patients are first After orthodontic treatment autologous dental transplant surgery, with steel or other fixed fixation; to be autologous dental autotransplantation after further successful treatment. Results Twenty-two patients were followed up from 1.5 to 4 years after operation. All the patients underwent dental implants. The morphology of the gingiva was basically good. The radiographs of the follow-up patients showed no evidence of root resorption. Conclusions Orthodontics combined with autologous dental transplantation for anterior impacted obstruction can effectively restore the shape of dental arch and oral function, and can also improve the appearance [2]. It can be used as an effective and feasible method for the treatment of anterior teeth ambush in the future medical development Impacted method in the clinical promotion.
