Materials and methods: Lateral cehalograms of 90 subjects were traced and various parameters associated with cervical column curvature were measured and related to sagittal jaw positions using statistical analysis consisting of descriptive statistics and intergroup comparison to find the level of significance for each parameter.

Results: Craniovertical angle was shown to have a statistically significant difference in all three groups. Also modified cervical angle (MCA) was shown to be significantly different in group A and group B. Lordotic curvature was found not to have a significant relation on different sagittal jaw position.

Conclusions: Modified craniocervical angle and craniovertical angle can be used to assess relation between cervical column curvature and sagittal jaw position.
