Abstract: A dental appliance for treating temporomandibular joint disorders that includes a U-shaped channel member having an inner side wall and an outer side wall. A plurality of connectors positioned between the inner and outer side walls divide the dental appliance into an upper and lower compartment for receiving a patient's upper and lower teeth, respectively. A pliable material fills the upper and lower compartments so that the grinding or clenching the patient's teeth is prevented and the patient's mandible can be set in a desired position.
