Abstract
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.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
102 words
A pre-formed orthodontic tooth positioning and retaining appliance comprising: a molded two-piece arch-shaped body of resilient material having an upper section and a lower section, said upper section having an archway formed on its top surface with a plurality of tooth sockets therein for receiving the teeth of the maxillary arch of a patient, said lower section having an archway formed in its bottom surface with a plurality of tooth sockets therein for receiving the teeth of the mandibular arch of the patient; and resilient means connected to the upper and lower sections for biasing the sections together in a traction relationship.
