Dentoalveolar morphology in relation to craniocervical posture.

چکیده
The associations between dentoalveolar morphology and the posture of the head and the cervical column were studied in a sample of 120 Danish male students aged 22-30 years. Two head positions were recorded on lateral cephalometric radiographs, one determined by the subjects's own feeling of a natural head balance (self balance position) and the other by the subject looking straight into a mirror (mirror position). Dentoalveolar morphology was described by 17 linear and angular variables and postural relationships by 18 angular variables. The position of the head in relation to the cervical column showed positive correlations with the anterior upper and lower dentoalveolar heights and with the inclinations of the upper and lower occlusal planes. These correlations were considered to reflect the dentoalveolar compensatory adaptation to the variation in vertical jaw relationship, which in a previous study had been found to be associated with craniocervical angulation. No associations were observed between craniocervical angulation and alveolar prognathism or incisor inclination. This was in accordance with the previous findings of a lack of associations between sagittal jaw relationship and craniocervical angulation.

INTRODUCTION In preorthodontic children with Class II malocclusion and horizontal maxillary overjet, cervical column morphology was examined and related to craniofacial morphology and head posture for the first time. METHODS Two hundred thirteen children (aged 7-15 years) with a horizontal maxillary overjet of more than 6 mm were divided into 2 groups of skeletal and dentoalveolar overjets. T...

Cross-sectional studies have demonstrated an association between craniocervical angulation and craniofacial morphology. It was the aim of the present study to determine if the growth coordination suggested by this association could be detected in a longitudinal analysis of growth changes in posture and craniofacial morphology. The sample comprised 43 children, 20 girls and 23 boys. Cephalometri...
