ABSTRACT
Aim
The aim of this study was to evaluate the dento-skeletal effects of mixed palatal expansion (MPE) on growing patients
with a uni- or bilateral posterior crossbite and mild-to-moderate crowding as compared to untreated growing individuals using postero-
anterior (PA) cephalometric analysis.
Methods
A group of 24 patients (18 girls and 6 boys) treated with a Hyrax-
type device was compared to an untreated matched control group at T0 (8.6 yrs 2.01) and T1 (10 yrs 2.00) using
PA cephalograms. The cephalometric analysis included eight bilateral skeletal and dental landmarks. The groups were compared using
independent sample t-test to estimate dento-skeletal effects on PA cephalograms.
Results
The treated group showed significant
changes for the maxillary width (P<0.001) and upper molar width (P<0.001) when compared to those of the control group.
Conclusion
MPE may effectively increase transverse dimensions and correct posterior crossbites.
