Direct vs Digitally Guided Miniscrew Placement for MARPE

Sponsor: Universitat Internacional de Catalunya

View on ClinicalTrials.gov

Summary

This randomized clinical trial compared the accuracy, primary stability, and anatomical safety of two protocols for palatal miniscrew placement in adolescents requiring maxillary skeletal expansion. Participants were randomly assigned to either direct appliance-guided miniscrew placement for MARPE or digitally guided CAD/CAM-assisted miniscrew placement. Postoperative CBCT imaging was used to assess placement accuracy and anatomical safety, while clinical evaluation was used to assess primary stability.

Interventions

PROCEDURE

Direct appliance-guided miniscrew placement

Palatal miniscrews were inserted manually using the MARPE appliance as the insertion guide according to the planned position.

PROCEDURE

Digitally guided CAD/CAM miniscrew placement

Palatal miniscrews were inserted using a tooth-supported CAD/CAM surgical guide based on digital planning.
