Abstract

AIM: The purpose of this study was to longitudinally analyse the morphology of maxilla and mandible over time in infants using a three-dimensional (3D) surface scanner. METHODS: Seventeen Japanese full-term infants participated in the study. Dental plaster models were fabricated every 3 months from 1 month of age to 12 months. The plaster models were scanned using the 3D surface scanner to create 3D models. The arch width, arch length, arch angle, palatal depth and palatal area of the 3D models were analysed.
