It is generally agreed that growth in palatine results from bone formation at the palatine sutures and lengthening of the alveolar processes, but the extent to which these two sites contribute to the depth and length of the hard palate remains unsolved. Hence, professionals should use quantitative assessments of the hard palate, which allow more accuracy in the diagnosis and assessment of this structure. Aim investigating the relationship between the length and depth of the skeletal hard palatine with facial growth type in adult subjects using CBCT scan.
