BACKGROUND OF THE INVENTION
This invention relates to a single leaf stemplant or subperiosteal bone anchor to provide a point of tension for the purpose of moving a dental patient's teeth.

Additionally, known anchors are not readily adaptable to a irregular bone surfaces which impedes osteointegration.
