| Abstract: |
A craniomandibular appliance for treating mandibular retrogranathism and craniomandibular disorders comprising a unitary insert of a remoldable thermoplastic in the form of a dental arch defined by inner and outer walls and an interconnecting web to form channels for receiving the dental arches. The web establishes a defined separation between the occlusal surfaces of the upper and lower teeth and positions the mandible in a more forward position to obtain a reduced click or non-click condylar position.

Having illustrated and described my invention, I claim:
1. A craniomandibular appliance for treating mandibular retrognathism and craniomanidbular disorders, comprising a unitary insert of a thermoplastic material in the form of a dental arch having inner and outer generally vertical walls spaced apart from each other and connected by a generally horizontal ribbed web defined independently of a patient's teeth to form upper and lower channels for receiving the upper and lower dental arches, respectively, of a patient's mouth and moldable within said mouth to a fixed configuration establishing a desired mandibular position, said ribs having a top surface for contacting the occlusal surfaces of the teeth such that said ribbed web establishes a defined separation between the occlusal surfaces at the upper and lower teeth when said teeth are positioned therein.
