Visualization and Evaluation of Changes after Rapid Maxillary Expansion
Journal Title: Journal of Oral Health and Craniofacial Science - Year 2017, Vol 2, Issue 1
Abstract
Objectives: The aim of the study was to develop a mathematical model for the visualization and evaluation of transversal palatal soft tissue changes; and to carry out a statistical evaluation of the changes in vertical and sagittal dimensions after rapid maxillary expansion treatment. Material and Methods: 33 Caucasian children with posterior crossbite, 10 boys and 23 girls, aged 7 to 10 years (median 8 years 8 months) were treated with tooth-borne Haas type expander. Dental casts were digitalized by scanner and on the basis of quantitative mesh shape CPD-DCA analysis, coloured morphometrical maps were created. The statistical significance of individual vertex displacements was calculated by performing Hotelling’s T2 paired test. To determine the significance of the vertical and sagittal profile changes, the paired t-test and Wilcoxon signed rank test were carried out in 20 patients
