Assessment of mandibular plane changes using conventional versus miniscrew-assisted rapid palatal expansion in adolescents

The objective of this study was to assess the cephalometric and transversal changes in growing patients (adolescents) using two different types of maxilla expanders: conventional rapid palatal expander (RPE) and miniscrew-assisted rapid palatal expander (MARPE). Our null hypothesis is that there are no significant differences between the two groups for the molar inclination, maxilla expansion amount, and mandibular plane changes. This study showed that there are no statistically significant differences between and after treatment for the mandibular angle changes; however, a moderate correlation was found with the molar inclination and mandibular plane angle in the MARPE group, for this reason, we suggest that MARPE group has a greater influence on the mandibular plane angle.
