Six dental linear measurements concerning to dental arch development were considered:
20 (link) (1) MTS (only in the exposed group), (2) arch perimeter, (3) arch width, (4) arch length, (5) intercanine width and (6) intercanine length. For participants with premature loss of deciduous canines or those who had no fully erupted canines, intercanine width and intercanine length were not measured.
A trained and calibrated operator (PN) digitally performed dental linear measurements in a blinded way, using the Autodesk Meshmixer software (v. 3.5.474, California, United States).
21 (link) All digital measurements were repeated after a 1-month interval, for evaluation of method error.
