[Computerized parametrization in orthognathodontics]

The relationship between unilateral posterior cross-bite and area and volumetric proportions of the palatal vault observed in the frontal plane were studied in 6 cross-bite cases before and after the correction of the malocclusion by removable appliances. Comparison of area and volume were carried out between the hemipalatal vault with the teeth in cross-bite and the hemipalatal vault with the teeth in good occlusion. The results demonstrated discrepancies of measurements between the two hemipalatal vaults before treatment. After the correction of cross-bite few or no asymmetries were recorded.
