Direct vs Digitally Guided Miniscrew Placement for MARPE

Sex: All

Ages: 12 Years – 18 Years

Healthy volunteers: No

Phase: NA

Enrollment: 40

Sponsor: Universitat Internacional de Catalunya

Location: Universitat Internacional de Catalunya Sant Cugat del Vallès Barcelona

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.

Eligibility Criteria

Inclusion Criteria: * Age between 12 and 18 years * Transverse maxillary deficiency requiring skeletal expansion * Midpalatal suture maturation stage B or C * Adequate palatal bone height for miniscrew insertion (≥9 mm) * No previous maxillary expansion treatment Exclusion Criteria: * Age \>18 years * Palatal bone height \
