The purpose of this study was to search of the relationship between natural cervical, cranio-cervical, cranial posture and anterior dentoalveolar morphology. Material consisted of natural head posture lateral cephalograms obtained from 52 dental students (32 female, 20 male) aged 19 to 29 years of School of Dentistry, University of Ankara. The six postural variables were measured on the lateral cephalograms. These variables describe the inclination of the cranial reference line (SN) to the true vertical and the cervical column, the inclination of the cervical reference lines (OPT and CVT) to the true horizontal the curvature of the cervical column. The 15 dentoalveolar morphological variables were measured. These variables describe the anterior upper and lower vertical dentoalveolar heights, the inclinations and position of the upper and lower incisor and the anterior occlusion. The relationships between the anterior dentoalveolar morphological variables and the postural variables evaluated by using correlation analysis. Significant correlations were found between upper incisors angulations-positions and position of the head in relation to the true vertical reference line. Lower anterior facial height was associated with the position of the head in relation to the cervical column. Overbite displayed marked correlations with the inclination of the cervical column to the horizontal reference line. Conclusively, natural head and neck posture effects anterior dentoalveolar morphology.
