An oral appliance for treating sleep apnea and bruxism is formed of a maxillary tray and a mandibular tray. The maxillary tray carries a maxillary bite pad projecting downwardly toward an opposed mandibular occlusal surface. The mandibular tray carries a mandibular bite pad projecting upwardly toward an opposed maxillary occlusal surface. The maxillary bite pad is posterior to the mandibular bite pad such that upon sufficient relative posterior movement of the mandibular tray, the maxillary bite pad engages the mandibular bite pad and limits posterior movement of the mandibular tray. At least one surface, chosen from the anterior face of the maxillary bite pad and the posterior face of the mandibular bite pad, defines a guide plane disposed at an upward and forward slant. The maxillary bite pad and the mandibular bite pad are engageable at the guide plane for advancing the mandibular tray along the guide plane upon vertical closure between the trays. A smooth pad is disposed over the occlusal surface of at least one of the trays, guarding the occlusal surface from engagement with the opposed bite pad.

A one-piece molded bruxism treatment device, which in its upright orientation, includes:a. an elongated generally flat thin planar flexible strip that has a generally U shape defined by a curved front part and a pair of legs extending rearward from the front part about a central longitudinal axis, each leg having a distal end portion, the front part and the legs having top and bottom edges,b. two generally planar bite pads oriented generally horizontally, each extending from the distal end portion of one of the legs and extending medially toward the other, each of the bite pads having top and bottom surfaces and adapted to be positioned on one side of the person's jaw between the vertically facing surfaces of a person's upper and lower teeth, andc. each the bite pads being, at least in part, resiliently deformable when the bite pad is clenched between the person's upper and lower teeth,d. the device further defining a plurality of apertures extending completely through selected parts of the band and the bite pads.

A one-piece molded bruxism treatment device which in upright orientation has top and bottom parts, including: an elongated band having a generally U-shape defining a closed front end part and legs extending rearward and adapted to be positioned around the outer surfaces of a person's upper gums and teeth, and two generally planar resiliently deformable bite pads oriented generally horizontally, each extending from one of the feet of the band medially toward the other.

A dental appliance for maintaining a separation between the occlusal plane surfaces of the posterior teeth in order to avoid or minimize the adverse effects of bruxism, especially while sleeping. The appliance comprises bitepad assemblies, side assemblies for adjustably receiving the bitepad assemblies, and a strap assembly for connecting the side assemblies. Bitepad cores are provided with solid projections and mechanical locks that enhance bonding with associated overmolds for improved durability. Side assembly flanges are divided to achieve independent flexibility and improved conformity for enhanced stability and comfort. A mesial area of the connecting strap assembly is thickened and rigidified to create a flare in the areas of the cuspid roots to minimize irritation and discomfort to the gum tissue.

A pre-fabricated, pre-programmed or custom-made guidance package is provided. The Anterior Guidance Package (AGP) of current invention is comprised of one maxillary guidance component and one mandibular guidance component produced in many shapes and sizes. Those components are attached to a maxillary retention piece and a mandibular retention piece, respectively when the mandible is at a point defined by an operator to provide ideal anterior guidance for the mandible, or to provide specialized guidance for a damaged stomatognathic system. In contrast to all current bruxism or Tempor-mandibular disorders (TMD) appliances, the AGP according to current invention provides a wide range of features and options including three-dimensional control, superior mechanical advantage and preferable vertical dimension at rest. The primary purpose is to provide a superior anterior guidance night guard including relief of centric occlusion / centric relation discrepancy for the amelioration of the damage and pain caused by bruxism.

The present disclosure provides a computer implemented method for automatic detection of teeth clenching and / or teeth grinding in a dataset representing the level of biting force vs. time of a subject, the method comprising the steps of a) calculating a threshold level of biting force assigned to time t=t1 based on a background level determined from the dataset at a prior time t=t1−Tback, where Ttrack is a first predefined period of time, b) checking the level of biting, and if the level of biting force at time, t, exceeds the threshold level assigned to time t for a second predefined period of time, Tclench / grind, then assigning an event of teeth clenching to time t, c) if an event of teeth clenching has been assigned to time t, then either waiting a predefined period of time 10 Twait, or waiting until the level of biting is below the threshold for another predefined period of time Tend, d) if no events of teeth clenching and / or teeth grinding have been assigned for a third predefined period of time Tsilence, then repeating steps a)-c), e) if events of teeth clenching and / or teeth grinding have been assigned for a third predefined period of time Tsilence, then repeating only steps b)-c).

The present invention provides a novel composition of matter comprised of a mixture of two specific classes of compounds—Free-B-Ring flavonoids and flavans—for use in the prevention and treatment of diseases and conditions associated with mouth, gums and teeth. This composition of matter simultaneously inhibits cyclooxygenase (COX) and lipoxygenase (LOX) enzymatic activity and reduces cytokine production at the mRNA level in normal, aged and damaged periodontal cells and tissues. This invention further provides a method for the prevention and treatment of diseases and conditions of the mouth, gums and teeth. The method for preventing and treating diseases and conditions of the mouth, teeth and gums is comprised of administering to a host in need thereof a therapeutically effective amount of a composition comprising a mixture of Free-B-Ring flavonoids and flavans synthesized and / or isolated from a single plant or multiple plants, preferably in the Scutellaria, Oroxylum, Acacia or Uncaria genus of plants and pharmaceutically and / or cosmetically acceptable carriers. Finally the present invention provides a method for the prevention and treatment of diseases and conditions of the mouth, teeth or gums, including but not limited to periodontal diseases, such as gingivitis, periodontitis, pulpitis, periodontal conditions caused by the physical implantation of oral dentures, trauma, injuries, bruxism, neoplastic and other degenerative processes; material alba, pellicles, dental plagues, calculus, and stains. Use of the composition described herein also affords the benefit of maintaining optimum saliva production and pH, minimizing bacterial growth, reducing the formation of pellicles and plague, inhibiting tooth decalcification and tooth caries (decay), promoting remineralization, which yields healthy gums, whitening teeth, maintaining healthy oral hygiene and reducing oral malodor (halitosis).

Provided is a soft flexible oral appliance having protuberances that mimic naturally occurring dental Tori. An upper, palatial appliance and a lower, mandibular appliance may be used in conjunction or separately to alleviate a variety of disorders, improve facial tone, and increase physical performance. The appliances are lightweight, thin, and do not prohibit normal speech patterns when in use. Small protuberances are strategically molded along key surfaces of each appliance to stimulate nerves in the tongue and affect forward protrusion. Forward positioning of the tongue dilates the airways of the throat improving breathing while the use is sleeping, playing sports, or talking. It also reduces bruxing, or grinding of the teeth. A method is further provided, for adding protuberances to other types of oral appliances, thereby conferring some of the benefits listed above on appliances originally intended for other dental uses.
