ABSTRACT:
A subperiosteal bone anchor has a base that is thin and moldable so the base can be conformed to bone where it is to be placed. The base is formed as a plurality of arms, and leaves with central holes in the leaves so screws can urge the leaves against the bone. The edges of the base are scalloped, and very thin to facilitate bone overgrowth. Central to the arms is a stem extending up, and having a variety of connection mechanisms for attachment of orthodontic appliances.
