A Comparative Study Between Modified Miniscrew-Assisted Rapid Palatal Expander And Modified Rapid Palatal Expander in Molar Distalization Using Cone- Beam Computed Tomography

A Comparative Study Between Modified Miniscrew-Assisted Rapid Palatal Expander And Modified Rapid Palatal Expander in Molar Distalization Using Cone- Beam Computed Tomography

Comparative study between modified miniscrew-assisted rapid palatal expander and modified rapid palatal expander in molar distalization using CBCT.

This research will be conducted as a prospective and randomized clinical trial.

Inclusion Criteria:

• Crowding >4mm
• Good oral hygiene
• Healthy periodontal condition

Exclusion Criteria:

• Presence of craniofacial syndromes or cleft palate
• History of previous orthodontic treatment
• Poor oral hygiene or active periodontal disease
• Contraindications to CBCT imaging (e.g., pregnancy, inability to remain still during the scan)
