Objectives: The aim of this work is to establish a correlation between rapid palatal expansion and changes in width, length and perimeter of the upper and lower arch.

Materials and methods: The study was conducted on a sample of 19 subjects treated with rapid palatal expander, divided into two groups, whose data were recorded before treatment and after 3 and 6 months with manual and digital methods. The parameters evaluated are inter-canine, interpremolar, intermolar, anterior-posterior widths and upper and lower arch length.

Results and conclusions: Optimal palatal expansion has occurred in both groups, whereas in the mandible the changes follow the maxillary expansion with a non-homogeneous distribution over time.
