Mini-screw Implants as Anchorage for Molar Intrusion.

Objective: To show the efficiency of mini-screw implants as anchorage for molar intrusion. Methods: Three patients with anterior open-bite and two patients with extruded molars were treated with mini-screw implants as anchorage for molar intrusion. Lateral cephalograms were taken at the beginning and the end of the treatment. The movement of molars in vertical dimension were analyzed. Results:In open-bite patients overjet and overbite were corrected, and the molars were average intruded 3.1mm. Conclusion:To intrusion molar, mini-srcew implant is an effective method.
