Class II Division 1 Malocclusion Treated with a Cervical-Pull Headgear: A Case Report.

Abstract

Orthodontic treatment for skeletal Class II malocclusion was undertaken with the aim ofachieving orthopedic correction by modifying the growth pattern. A case of Class II, Division 1 malocclusion in the late mixed dentition was corrected to a Class I molar relationship by primarily using cervical-pull headgear. Cephalometric analysis indicated a reduction in the maxillo-mandibular discrepancy (ANB°) due to the correction of a skeletal Class II malocclusion to a Class I occlusion. The superimposition demonstrated that this was achieved by favorable growth of the mandible, control of maxillary first molars in an antero-posterior direction and retraction of maxillary incisors. Proclination of mandibular incisors was reduced. Significant improvement in the soft-tissue profile was noted.
