Abstract
OBJECTIVE: The purpose of this cephalometric study was to compare the difference of NHP (natural head posture) and spinal position among malocclusions with different skeletal patterns. METHODS: 79 malocclusions aged from 12 to 16 were divided to several groups according ANB and NSL-MP. The features of head posture and spinal position were examined by comparing the groups and the statistical significant correlation among NHP, spinal position and craniofacial morphology was sought. RESULTS: NHP and spinal position was not the same in malocclusions with different NSL-MP, while was identical in malocclusions with different ANB. CONCLUSION: It is believed that there was correlation among NHP, spinal position and vertical, sagittal development of face rather than anteroposterior relationship between maxilla and mandible.
