For the purpose of investigating the characteristics of the palatal morphology of the
children with crossbite in primary dentition, study casts were taken from 22 children
with crossbite and 23 children with normal occlusion as control with age of 3.2¡­4.5
years. From the casts, the mean curves representing the palatal morphologies were
drawn with surface contour and roughness measuring machine. The data were processed
to make the mean curves of palate in each group and the curves were compared
statistically.
The results as follows :
1. Comparing the palatal shapes in sagittal plane, the palate of crossbite group showed
stronger tendency of deepening as approaching posteriorly than control(normal occlusion)
group(P<0.05).
2. Comparing the palatal shapes in intercanine cross-sectioned transverse plane, the
palate of crossbite group appeared flatter all over the area than those of control
group(P<0.05).
3. In intermolar cross-sectioned transverse plane, no significant differences were found
in the palatal shapes between two groups.
