A dentally retained intra-oral appliance worn at night for treatment of snoring and obstructive sleep apnea and its fabrication process. The appliance maintains the patient's mandible in an anterior, protruded position to prevent obstruction of the pharyngeal airway. The appliance allows a limited degree of lateral movement of the mandible relative to the upper jaw in the protruded position to prevent aggravation of the patient's temporomandibular joint and associated muscles and ligaments. The appliance includes a lower bite block conforming to the patient's mandibular dentition, an upper bite block conforming to the patient's maxillary dentition, and a hinge connecting the upper bite block to the lower bite block. The upper bite block and the lower bite block are thin walled polyamide eliminating the need for dental wires to maintain them to the mandibular detention and the maxillary dentition and the problems associated therewith.
