Brief summary
Comparative study between modified miniscrew-assisted rapid palatal expander and modified rapid palatal expander in molar distalization using CBCT.
Detailed description
This research will be conducted as a prospective and randomized clinical trial.
Interventions
DEVICEGroup A: Modified Miniscrew-Assisted Rapid Palatal Expander (MARPE)
A skeletal anchorage-supported with miniscrews inserted into the palate using a self-drilling technique.
DEVICEGroup B: Modified Rapid Palatal Expander (RPE)
A tooth-borne anchorage focusing on molar distalization .
