Dynamics of changes in transverse and frontal-retromolar jaw sizes in children throughout the orthodontic treatment stages

Abstract

Through the biometric study of jaw models individual dimensions of the dental arches (upper and lower jaws) and hard palate were evaluated in children aged 3-4 years with optimal functional occlusion and malocclusion. In two years of dynamic observation in children with optimal functional occlusion a slight increase in the transversal sizes of the upper and lower teeth rows, as well as the width and height of the palate were found. As a result of the orthodontic treatment in children with malocclusion there was found an increase in frontal-retromolar and transverse dimensions of the dental arches of the upper and lower jaws combined with widening of the palate, while the change in the height of the palate was not statistically significant.
