Mandibular repositioning devices providing downward movement as well as forward movement of the mandible have a maxillary tooth covering having a driver flange protruding laterally outward on one or both sides thereof and have a mandibular tooth covering having a protrusive flange extending cranially therefrom positioned to have a posterior side engaged with the anterior side of each driver flange. The anterior side of each driver flange has a convex curvature. The posterior side of each protrusive flange has a concave-to-convex curvature positioned to move the convex portion thereof along the convex curvature of the driver flange when the mouth opens, which also moves the mandible forward. A plateau of a preselected height, which prevents disconnect between each protrusive flange and its respective driver flange relative to a fully open mouth measurement, is present between the base of the protrusive flange and the tooth covering.

The present invention addresses the problem of providing: a mouthpiece having a shape that adequately conforms to the teeth rows, etc., of a user, the mouthpiece having an excellent feel during wearing; and a method for manufacturing the mouthpiece. A mouthpiece for solving the abovementioned problem includes a mouthpiece body part having a hard section, which has a groove for accommodating the teeth rows and/or the gums, and a soft section, which contains a material having a lower bending elasticity than that of the hard section. The proportion of the maximum thickness of the soft section to the minimum thickness of the soft section is 5 or greater.

An oral appliance allows the mandible to move forward, without putting strain on the temporomandibular joint and surrounding muscles, so that the oral appliance may be worn for a long time during sleep, thereby improving snoring. In addition, the oral appliance allows the tongue to move forward together with the mandible so that the tongue is naturally placed in the anterior region of the palate to induce conversion of mouth breathing to nasal breathing, thereby improving both snoring and sleep apnea.

A habit corrector appliance including a front portion, a first ramp and a second ramp extending from the front portion. The first ramp is located at a high position adjacent to or at a user's palate to ensure the tongue is positioned at the palate which widens the palate and which also prevents or reduces mouth breathing. The second ramp is located at a position lower than and beneath the first ramp, wherein the second ramp substantially prevents the tongue from entering a lower space within the oral cavity, wherein the first ramp aids in an elevated tongue position and the patient learns to swallow with the tongue elevated to substantially reduce or prevent air from entering the oral cavity through the mouth and to prevent mouth breathing. Slits at the ramp sides allow for lateral expansion of the appliance. Lingual tabs promote proper anterior positioning of the jaws. A lingual wire with narrower anterior wire extensions can provide a widening of the arch and movement of the upper incisors and maxilla in a forward position.

A heat exchanger is disclosed for causing cryolysis of adipose tissue of a human tongue. The heat exchanger includes a body having cooling channels for circulating fluids therein. The body forms a contact surface that contacts a portion of the dorsal surface of the tongue and a portion of the base of the tongue. The heat exchanger includes a pair of side walls extending from the body and forming a pair of side contact surfaces that are dimensioned so that they contact the dorsal and lateral surfaces of the tongue in a manner so as to constrict the tongue when the contact surface is in contact with the tongue. A method of treatment for apnea using the heat exchanger and/or administering a chemical adipolysis formulation/vasoconstriction agent is also disclosed.

An oral appliance having an upper tray, a lower tray, and axial inserts attached to the upper tray to adjust the relative position of a user's upper jaw and lower jaw in order to treat sleep apnea and/or snoring while at the same time allowing orthodontic treatment of the subject.

The present invention relates to a method of operating a smart mattress system for preventing snoring which can stop snoring of a user, wherein an air mattress and an air pillow interlock with a user terminal so that a user can easily control the air mattress and the air pillow.

A system includes a collar that is worn around a neck of the user. A stimulator is coupled to the collar such that the stimulator is positioned adjacent to an airway of the user. The sensor is coupled to the collar and configured to generate data associated with the airway of the user. The memory is coupled to the collar and storing machine-readable instructions. The control system is coupled to the collar and includes one or more processors configured to execute the machine-readable instructions to determine, based at least on an analysis of the generated data, that the user is currently experiencing an apnea event. In response to the determination, the control system causes the stimulator to provide electrical stimulation, at a first intensity level, to one or more muscles of the user that are adjacent to the airway to aid in stopping the apnea event.

A dental intraoral device that is worn within an oral cavity, the dental intraoral device comprising a resin base portion that follows a shape of the oral cavity. At least a part of the base portion is formed into a mesh shape. The part of the base portion is preferably formed by approximately regularly arranging unit regions having holes.
