Does age influence lip position relative to the dental support? : a three-dimensional evaluation in a healthy group

The mastoid process originates from a recent phylogenetic formation and is currently considered as an evolution of the supper-structures bones. Tha iam of this study was the detailed description of the anatomic elements of the mastoid and the temporal bone in a large Greek adult corpse material. In total, 298 temporal bones from 149 cadaverous (74 male and 75 female) were examined from 1973 through 1993. Concernong tha shape of the mastoid apex 94.0% were normal, while the rest presented several variations No statistically significant difference was revealed between genders. Tha diameters and axis of the temporal bone presented an independent correlation wiht gender in a multiple regression model. This prescription may add in easier surgical approach by adding new morphological deatils directly from the corpse material.
