目的探讨治疗上颌前牙埋伏阻生中应用固定正畸技术的临床疗效。方法方便选取该院2013年1月—2016年1月收治的50例上颌前牙埋伏阻生的正畸患者,采用固定正畸矫治技术采用直接牵引或者扩开后隙牵引,开放式或者封闭式牵引导萌埋伏阻生牙齿,完成矫治后观察萌出牙可否出现牙周、根尖、牙髓等病变,是否发生牙根吸收等症状。结果 8例患者24颗牙中行助萌术治疗的6例8颗牙,经过治疗后,3~6个月全部自然萌出,完成矫治后萌出牙没有牙周、根尖、牙髓等病变,患者对治疗效果满意。行导萌术治疗的12例18颗牙,治疗后5~12个月后均埋伏牙萌出排齐,其中除1颗出现牙周附着不足外,其余均经检查牙周组织正常,未发生牙根吸收等症状。结论治疗上颌前牙埋伏阻生中应用固定正畸技术,可对患牙进行有效的矫正,既可有效保存患牙,又可减少并发症的产生,远期疗效更明显,是临床中理想的矫治方法。
Objective To investigate the clinical effect of fixed orthodontics in the treatment of impacted obstruction of the maxillary anterior teeth. Methods Convenient selection of the hospital from January 2013 to January 2016 admitted 50 cases of maxillary anterior teeth impacted orthodontic patients using fixed orthodontic treatment using direct traction or open backlash traction, open or closed Traction guide sprouting impacted teeth, after completion of treatment to observe the eruption of teeth can appear periodontal, apical, dental pulp and other lesions, whether the occurrence of root resorption and other symptoms. Results 6 cases of 8 teeth treated with sprouting in 24 teeth of 8 patients were erupted naturally after 3 to 6 months. There was no periodontal, apex and pulp disease in eruption teeth after the treatment, Satisfaction with the treatment. In 12 cases, 18 teeth were treated with lead-induced sprouting technique. After the treatment, all the impacted teeth were erupted out of alignment after 5 to 12 months, except for 1 case with insufficient periodontal attachment, the remaining periodontal tissues were normal and no root Absorption and other symptoms. Conclusion The application of orthodontic technique in the treatment of impacted obstruction of the maxillary anterior teeth can effectively correct the affected teeth, which can effectively save the teeth and reduce the complications. The long-term effect is more obvious and is ideal in clinical practice Correction method.
