Three dimensional measurement of the palate using the semiconductor laser
2. Changes in the palate section areas, palate projection areas and palate volumes in the mixed dentition

Abstract

The objective of the study was to examine changes in palate sectional areas, palate projection areas and palate volumes according to age. Using the maxillary dentition models, the palates of 7-, 8- and 9-year-old children, who were in the mixed dentition period, were measured three-dimensionally using the semiconductor laser. The palate section areas, particularly between deciduous canines, primary first molars, primary second molars and first molars, increased with age, as the palate expanded vertically along with the growth and development of the maxilla. The palate projection areas increased with age, as the palate expanded laterally along with the growth and development of the maxilla. The palate volume increased with age, as the palate expanded laterally and vertically.
