Abstract
The present invention relates to a device for performing bone distraction and/or tooth movement, and more particularly to a widening or contracting device which is capable of effecting bone distraction in more than one plane of space simultaneously. In its broadest aspects, the present invention is a device that can be used for bone distraction or osteogenesis, as well as tooth movement, which includes an expandible (or contractible) member for affixation in the oral cavity of a patient. The device is adapted to provide distraction of a selected craniofacial bone, such as the mandible, or movement of teeth, simultaneously in more than one plane of space. The expandible (or contractible) member includes a mechanism for expanding (or contracting) the expandible (or contractible) member to achieve the desired distraction of the selected bone or movement of selected teeth.
