ClinConnect Summary

Purpose:

This prospective study is aimed to investigate the patient-reported treatment outcomes and the dental-skeletal treatment effects on palatal dimensions and to compare them with those of traditional maxillary expansion.

Hypothesis:

The null hypothesis will be:

* 1: There are no differences in the inter-canine, inter-molar width, and molar inclination between IFPE and RME groups.
* 2: There are no differences in the arch width, length, size and shape, palatal surface area and volume, plaque index, and white spot lesion formation between IFPE and RME groups.
* 3: There are no diffe...
