Abstract
Aims: To determine the parallelism of the occlusal plane to the different alatragal lines and to evaluate the parallelism of maxillary and mandibular residual ridges/ basal bone to the three ala tragal lines. Material and Methods:Forty dentulous and forty edentulous subjects were included in the study. Four radiological markers have been placed- one each on superior, middle, inferior position of tragus and one at the ala of the nose. Lead foil is placed on the intaglio surface of the maxillary and mandibular dentures . Then the Lateral cephalograms was made and traced. Statistical analysis: Was subjected to ANOVA test and post hoc test of Bonferroni. Results: The alatragal line passing through the inferior position of the tragus to the ala of the nose is relatively parallel to the reference planes studied and helps to establish occlusal plane during complete denture fabrication.
