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.
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.
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.
The mandibular cervical headgear is a good alternative for the treatment of these cases and is well-accepted and tolerated by the patients.
