Summary

The aim of this prospective clinical study is to evaluate and compare the changes in occlusal force distribution using a quantitative digital occlusal analysis system following piezocision-assisted rapid maxillary expansion (RME) in adolescent versus young adult orthodontic patients. The study hypothesis is that piezocision-assisted RME will result in significant changes in occlusal force distribution and that these outcomes may differ between age groups over a 3-month follow-up period.
