| Research Abstract |
Bone formation surrounding titanium mini-screw was induced by irradiation of Low-intensity Pulsed Ultrasound(LIPUS) for 1 week after the placement. Bone-miniscrew contact ratio was improved and mobility of the screw decreased in the test group. Bone surrouding the screw was also elaborated in scanning electron microscope images. It was then suggested that endosseous stability of the miniscrew was improved by LIPUS irradiation.
