An osteogenic support device for an orthodontic treatment comprises a platform, lower and upper projections extending downwardly and upwardly from the platform. The upper projection is substantially tapered from the platform toward a cap. The upper protection has a through opening substantially perpendicular to an axis of the lower projection. A first end of the elastic wire is hooked between the cap and the platform, and a second end of the elastic wire is hooked with an orthodontic wire which links each bracket attached on teeth of the orthodontic patient.
