Introduction
There are various studies in the literature on using different measurements and methods regarding the anteroposterior and vertical positions of the lower and upper jaws.

Aim
The aim of the study was to evaluate the relationship between different parameters used in defining the anteroposterior relationship of the jaws in individuals with different vertical facial growth types.

Material and methods
Lateral cephalometric radiographs of 150 patients with different vertical facial growth types [Low-Angle (LA), NormAngle (NA) and High-Angle (HA)] and skeletal Class-I malocclusion were included in the study. The ANB, Wits appraisal, A-Nperp, Pog-Nperp, Beta, W and Yen angles were used to determine the sagittal relationship of the jaw and were evaluated in comparison with each other.

Results
Wits appraisal, Pog-Nperp, Beta, W and Yen angle parameters were found to differ significantly between groups(p<0.05). Wits appraisal, Pog-Nperp and Yen angle parameters were found to be significantly lower in HA-individuals than LA-individuals, while the Beta angle was found to be significantly higher in HA-individuals than LAindividuals(p<0.05). Beta and W angles were significantly lower in NA-individuals than HA-individuals(p<0.05). It was determined that the ANB, Beta, W and Yen angles used in the evaluation of the sagittal relationship of the jaws showed a significant correlation regardless of the vertical growth type of the face(p<0.05).

Conclusions
This study interprets the relationship between different sagittal parameters according to the vertical growth pattern of the face. The sagittal parameters that are usable in all three groups are ANB, Beta, W and Yen angles, and Wits appraisal.
