Growth Changes of the Palate

¹ Forsyth Dental Infirmary-Harvard School of Dental Medicine, Boston, Massachusetts

Growth changes of the palate were studied in thirty longitudinal series of dental casts (13 boys and 17 girls), including the transition from the deciduous to the permanent dentition. The symmetrograph of Korkhaus was utilized for measurements and tracings of the mid-sagittal and transversal contours of the palate. The relative stability of the rugae was used as reference. Results showed that the alveolar processes increased in height and breadth continuously. The shape of the top of the palatal vault remained essentially constant except for an increment in breadth at the apex of the palatal vault in three-fourths of the sample. It was not possible to define whether this increment was due to growth at the mid-palatal suture, to bone remodeling, or to the association of both.
