摘要： 目的:探讨采用引流助萌的方法对伴囊肿的上颌埋伏阻生中切牙的早期治疗。方法:选取单侧上颌中切牙埋伏阻生、处于替牙早期伴囊肿的患者8例。外科囊肿切除同时对埋伏阻生上颌中切牙引流助萌治疗。治疗前后拍摄CBCT,Dolphin11.0软件测量矫治前后阻生牙及对侧正常同名牙的冠根长度。结果:8例患者的埋伏阻生上颌中切牙平均矫治时间6.7个月。矫治后阻生牙和对侧正常同名牙的冠根长度均有生长。阻生牙冠根长度较对侧正常同名牙明显短(P<0.05)。结论:本研究所采用引流助萌方法为埋伏阻生牙的矫治提供了一个安全、有效的新途径。

Abstract: Objective: To investigate the early management for maxillary osseous impacted incisors with dentigerous cysts by using draining and guiding eruption method. Methods: Eight patients who had unilateral maxillary impacted incisor with dentigerous cyst in the early mixed dentition were selected. Eigth impacted teeth were treated with the draining and guiding eruption technique simultaneously after the cyst excision. All patients were taken CBCT scan examination at pre- and post-treatment time. The crown-root lengths of the impacted and the contralateral teeth were measured with Dolphin 11.0 software. Results: The average treatment duration was 6.7 months. After treatment, the crown-root lengths of both the impacted teeth and the contralateral teeth were greater than their pretreatment values. The crown-root lengths of impacted teeth were significantly shorter than that of the contralateral teeth (P<0.05). Conclusion: The draining and guiding eruption technique in the research provided a new safety and effective approach for the management of the impacted teeth with dentigerous cysts.
