ABSTRACT:
An orthodontic face bow for applying at least extrusion and/or intrusion forces to teeth in a controlled and reliable manner comprises an inner bow member having first and second ends to be coupled to respective teeth in the mouth; and an outer bow member coupled to the inner bow member at a substantially central portion thereof, the inner and outer bow members being rotatable relative to each other. A resilient biassing means is coupled between the inner and outer bow members for resiliently biassing one of the bow members relative to the other to cause one of the bow members to rotate relative to the other to apply at least one of the aforementioned extrusion and intrusion forces to the teeth to which the inner bow member is coupled. Also disclosed is an arrangement in which the inner and outer bow members are both mounted intra-oral and further arrangements which limit the amount of rotation of one of the bow members relative to the other.
