At least one of the maxillary abutment assembly and the mandibular abutment assembly has an advancement adjustment structure comprising at least one adjustment spacer removably securable to the corresponding one of the maxillary splint and the mandibular splint. The at least one adjustment spacer has a spacing length defining the mandibular advancement provided by the set of mandibular advancement splints. A set of removable adjustment spacers, a mandibular advancement kit, and a method for adjusting a mandibular advancement produced by a set of mandibular advancement splints are also provided.

The present invention relates generally to the field of mouthguards. More specifically, the present invention relates to a mouth guard system and method of use. The system is primarily comprised of a kit, at least one mouthguard, a mobile application and a method of use. The mouthguard of the system is preferably manufactured from a rigid, transparent, BPA-free material and can be worn during sleep to correct malocclusion to improve and prevent postural dysfunction, tensions headaches and other body ailments. The method of use further involves using a mold to create a custom mouthguard for a user, wherein the user can then wear the mouthguard and track postural changes induced by the mouthguard via a mobile application.

A liner for use with a respiratory mask having a frame portion which is detachable from a cushion portion is provided, the liner including a body constructed from an absorbent material, the body having a first end and a second end, the body including a hose aperture adjacent the first end and sized for placement over a hose connector of the respiratory mask, and a mouth aperture adjacent the second end for placement over a mouth opening of the mask to allow air to flow into a user's mouth.

A single arch dental device. The single arch dental device includes a dental trough, having a lingual surface, a facial surface, and an occlusal surface. The dental trough is molded to conform to a shape of a wearer's lower teeth. The facial surface of the dental trough has an anterior facial surface and a posterior facial surface. The posterior facial surface of the dental trough is contoured to receive a facial surface of the wearer's teeth. The lingual surface of the dental trough has an anterior lingual surface and a posterior lingual surface. The anterior lingual surface of the dental trough is contoured to receive the lingual surface of the wearer's teeth. A pocket is carved out of the posterior lingual surface of the dental trough and provides a surface into which an anterior and lateral border portion of the wearer's tongue rests.

A dental guard for treatment of bruxism in a human dental arch. The dental guard comprises an elastically deformable body having a front band portion and a pair of molar portions contiguous with and extending from the ends of the front band portion. The distance between distal ends of the molar portions is configured to differ from the width of the human dental arch. The front band portion and molar portions form a U-shape configured and may have less curvature than a curvature of the human dental arch. The body includes a front side wall and an upper side wall extending at an angle from a longitudinal edge of the front side wall. The body is adapted to be positioned to fit over a plurality of teeth such that the inner surfaces of the front wall and the upper wall engage occlusal surfaces of the posterior teeth. When the jaws are closed the body at least partially conforms to the outer surfaces and occlusal surfaces of differently sized and differently shaped teeth corresponding to different people during use.

The disclosed dental appliance is a functional daytime and nighttime anatomical removable dental appliance that is designed to overlay the existing natural dentition of the user. In desirable embodiments, the appliance can be held in place without any alterations to the user's existing dentition. The appliance is a plural piece or plural section intra-oral removable appliance with occlusal surface portions that have been built up to occupy the measured intra-occlusal spaces that exist between pairs of upper and lower teeth when the mandible is in a relaxed or rest position.

Disclosed herein are methods of manufacturing an oral appliance, the method comprising the steps of: a) importing into a computer aided design (CAD) computer program a digitized data set obtained from a three-dimensional scan of a patient's dentition; b) preparing a three-dimensional electronic model of the patient's dentition; c) subtracting the three-dimensional electronic model of the patient's dentition from an image of a solid block to obtain an appliance data set; and d) manufacturing a dental appliance in accordance with the appliance data set. Also disclosed are devices made by the above method, and methods of treating a condition, for example a sleep breathing disorder, by using a device made by the above method.

An appliance for use in a method of reducing facial aging and/or oral parafunctional activity comprising two parts, each comprising a composite structure comprising: a first layer formed of a durable, resilient, elastomeric material comprising a cured thermoset rubber and which in use contacts the occlusal biting surfaces of the posterior teeth; and a second layer formed of a durable, non-deformable material having a softening point over 100° C. which provides a bite plate; wherein the second layer of each part is provided with a protrusion formed of durable, non-deformable material having a softening point over 100° C. which is positioned such that in use the protrusion extends from the surface above at least a part of the first and/or second molar teeth which are in contact with the first layer. A method of making the appliance, a kit of parts, and methods of use are also disclosed.
