[A cephalometric study of natural head posture and spinal position in malocclusions].
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.


CONCLUSIONS
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.
