Abstract: A mandible extension dental device (10) is provided which includes adjustable upper and lower arch trays (12, 14) and coupling means (16) designed to pull the lower jaw of a user forwardly during sleep, so as to minimize snoring and mild apnea conditions. Each of the arch trays (12, 14) includes a substantially rigid synthetic body (18, 38) equipped with a pair of generally L-shaped, continuous adjustment slots (32, 34 and 46, 48). Thermoplastic molding material (36, 60) within each tray (12, 14) permits custom fitting of the trays (12, 14) to the upper and lower arches of a patient. During such fitting, the tray bodies (18, 38) are adjusted as necessary owing to the provision of the slots (32, 34 and 46, 48) to accommodate the arch configurations of the patient. Once the material (36, 60) hardens, the patient-specific arch configurations are permanently retained. The device (10) can be rapidly fitted in the field without the need for the services of a dentist.

Abstract: A comfortable, leak-resistant CPAP nose mask (10) is provided having a soft, resilient, synthetic resin body (12) and an air source connection fitting (14). The body (12) presents an internal nose-receiving cavity (20) as well as a generally triangular nose entrance opening (16) and a spaced, opposed, inhale/exhale opening (18); the openings (16,18) are in communication with the cavity (20). The entrance opening (16) is defined by a circumscribing flange (20) and an inboard, pliable, inwardly extending, sealing lip (32). A metallic, deformable, shape-retaining reinforcing member (42) is secured to the outer surface of the flange (22) and extends over the bridge (24) and sidewall regions (26, 28) of the flange (22). The member (42) can be readily shaped so as to accommodate the shape and contour of the user's nose and face.
