INTRODUCTION
Cleidocranial dysplasia (CCD) is a rare inherited skeletal dysplasia, often with prolonged retention of deciduous teeth and several impacted permanent successors and supernumerary elements.
METHODS
This article demonstrates the usefulness of titanium screws for orthodontic anchorage to induce eruption of the impacted teeth in a patient with CCD. A boy, aged 10 years 11 months, had a number of impacted permanent teeth. After the supernumerary teeth were extracted and the incisors were surgically exposed, 2 titanium screws were placed in the palate without incisions or flap surgery. After implantation, a lingual arch appliance was placed, and orthodontic load began 4 weeks after surgery with an elastic chain.
RESULTS
After 4 months of traction, 3 impacted incisors had erupted into the mouth.
CONCLUSIONS
This new method for retraction of impacted teeth can reduce the patient's treatment time and psychological stress. Treatment with titanium screws for traction of impacted teeth might be a new treatment strategy for managing CCD patients.
引言
锁骨颅骨发育不全（CCD）是一种罕见的遗传性骨骼发育不良，常伴有乳牙滞留时间延长以及多颗埋伏恒牙和额外牙。
方法
本文展示了钛钉在正畸支抗中用于诱导一名CCD患者埋伏牙萌出的有效性。一名10岁11个月大的男孩有许多埋伏恒牙。在拔除额外牙并手术暴露切牙后，未进行切口或翻瓣手术，在上腭植入了2颗钛钉。植入后，放置了舌弓矫治器，并在术后4周用弹力链开始正畸加力。
结果
牵引4个月后，3颗埋伏切牙萌出到口腔内。
结论
这种新的埋伏牙牵引方法可以减少患者的治疗时间和心理压力。用钛钉牵引埋伏牙进行治疗可能是管理CCD患者的一种新的治疗策略。
