Abstract
A subperiosteal bone anchor used in two distinct applications; as an orthodontic anchor system, and as an orthopedic anchor system. As an orthodontic anchor system, it is used for treatment of growth disharmony and malalignment of the teeth in which the subperiosteal bone anchor is surgically placed in the subperiosteal tunnel on skeletal bone allowing osseointegration between the subperiosteal bone anchor bone interface and the bone. After osseointegration a palatal bar or palatal wire is attached to the cylinder of orthodontic anchor system, which is attached to the abutment, which is attached to the subperiosteal bone anchor, and the palatal bar or palatal wire is also attached to bands around one or more teeth, holding them immobile. As an orthopedic anchor system the subperiosteal bone anchor is used to stabilize devices which need to be anchored to a bone, or to transmit attractive or distractive forces to a bone for reconstruction or transformation.
