AbstractAims: The aims of this study are planned to evaluate the cranial base parameters of the short upper anterior facial height of open bite occlusion and compare them with the normal occlusion. Materials and Methods: The total sample of this study was 48 cases, divided into 12 case for each male and female of the normal class 1 molar occlusion and short upper facial height with open bite cases. The age of the patients was ranged between 13-15 years. A lateral cephalometric radiograph film was taken. All the cephalometric x-rays were analyzed to evaluate the cranial parameters and the upper anterior facial height. The data subjected to statistical analysis by using student t-test to distinguish the significant differences at 0.05 level for the short upper anterior facial height and to record the cranial parameters of the sample. Results: The comparison of the cranial parameters between the normal and open bite occlusions , the male expressed no significant difference ( at 0.05 level ) in the parameters except the liner (S-Ar) and the angular (N-S-Ba, N-S-Po and N-S-Co).While the female displayed no significant difference (at 0.05 level) in parameters except (N-S-Ba and N-S-Po angles). Conclusions: The short upper anterior facial height with anterior open bite case has influences on the cranial base development especially on (S-Ar, N-S-Ba, N-S-Po and N-S-Co).
