ABSTRACT
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.

In recent times, the use of miniscrew implants to obtain absolute anchorage has gained momentum in clinical orthodontics as rigid anchorage modality. Miniscrew implants offers many advantages when used as temporary anchorage devices like, easy placement and removal, immediate loading, can be used in a variety of locations, provide absolute anchorage, economic and requires less patient cooperation. This makes them as a necessary treatment option in cases with critical anchorage that would have otherwise resulted in anchorage loss if treated with conventional means of anchorage. The aim of this comprehensive review is to highlight the gradual evolution, clinical use, advantages and disadvantages of the miniscrew implants when used to obtain a temporary but absolute skeletal anchorage for orthodontic applications.
