RESUMEN

OBJECTIVE: The study was undertaken to evaluate and compare the stability and surrounding soft tissue reaction of the Drill and Drill-free miniscrews when used as anchorage unit for en-masse retraction of maxillary anteriors. METHODS: 20 patients were selected. Of the total 20 Drill and drill free screws, halfscrews were placed on the right side and half on the left side of maxilla and clinical evaluation for mobility and any surrounding soft tissue inflammation was done. RESULTS AND CONCLUSION: There were no statistically significant differences with respect to Stability/Failure and soft tissue reaction for Drill and Drill-free screws when used as anchorage units.
