AIM
To show craniofacial and dental changes to the mandibular dentition with the use of cervical headgear as well as the mechanics used in the early management of Class III malocclusions.
METHODS
Clinical photos and cephalometric radiographs of 5 patients with different types of Class III malocclusion treated with mandibular cervical headgear are shown in this article.
RESULTS
The use of the mandibular cervical headgear showed to be clinically effective in the treatment of different types of Class III malocclusions. The main effects of the appliance were posterior and anterior rotation of the mandible and distalization of the mandibular molars.
CONCLUSION
The mandibular cervical headgear is a good alternative for the treatment of these cases and is well-accepted and tolerated by the patients.
目的
展示使用颈带矫治器时下颌牙列的颅面及牙齿变化，以及Ⅲ类错牙合早期治疗中所采用的力学原理。
方法
本文展示了5例使用下颌颈带矫治器治疗的不同类型Ⅲ类错牙合患者的临床照片和头影测量X线片。
结果
下颌颈带矫治器在治疗不同类型Ⅲ类错牙合方面显示出临床有效性。该矫治器的主要作用是使下颌发生后旋和前旋以及使下颌磨牙远中移动。
结论
下颌颈带矫治器是治疗这些病例的良好选择，且患者易于接受和耐受。
