Abstract
A gnathologic orthodontic positioner which is split to provide an upper section for the maxillary arch and a separate lower section for the mandibular arch, the two sections being held together by elongated resilient members, such as elastics and/or by magnetic force. The upper and lower sections are attached to the teeth by mechanical clasps which may be assisted by suction cups.
