An analysis of the relationship between posterior dental cross-bite and vertical palatal asymmetry.

The relationship between unilateral posterior cross-bite and vertical proportions of the palatal vault observed in the frontal plane was studied in twenty cross-bite cases wtih asymmetric palates and twenty control cases. The contour of the palate was registered from study models at three different anteroposterior levels with an adjustable template. The tracings of the contours obtained from roentgenograms of the instrument were used to measure the asymmetry of the palate.
