ABSTRACT:
An orthodontic face bow in which the outer bow is coupled firmly but separably to the inner bow by magnetic means and the inner bow is coupled to opposite molars in the mouth of the patient by a combination of mechanical and magnetic means, all to the end that, at a predetermined force the outer bow will separate from the inner bow and, at a higher force, the inner bow may be removed from the mouth of the patient so that prevention of injury to the patient by the inner bow may be prevented.
