Abstract: An intraoral discluder for preventing chronic tension headaches, common migraine headaches, and temporomandibular disorders that are caused or perpetuated by chronic activity of the temporalis muscle. The discluder includes a trough, contoured to encompass at least one maxillary or mandibular incisor, from which extends a protruding platform, for engagement by the opposing incisors. The trough can be retained on the teeth by any adaptable material than can flow around the teeth and then maintain its shape. Once in place in the wearer's mouth, one or two opposing incisors will come into contact with the platform prior to the upper and lower posterior and/or canine teeth coming into contact, regardless of the position of the mandible, thereby reducing the intensity of the activity of the temporalis muscle.

Abstract: A semi-custom intraoral discluder device for preventing chronic tension and common migraine headaches and temporomandibular disorders that are caused or perpetuated by chronic activity of the temporalis muscle. The discluder includes a trough, contoured to encompass at least one maxillary or mandibular incisor, from which extends a protrusion, typically of a dome shape. The trough can be retained on the teeth by any adaptable material which can flow around the teeth and then maintain its shape. The adaptation of the retentive material can be performed by the end user, health care provider, or anyone trained in the art. Once in place in the wearer's mouth, one or two opposing incisor teeth will come into contact with the protrusion prior to the upper and lower posterior and/or canine teeth coming into contact, regardless of the position of the mandible, thereby reducing the intensity of the activity of the temporalis muscle.

Abstract: A method of making an occlusally retained mouthpiece. A mouthpiece substrate is coated with a resin precursor that is neither caustic nor irritating to teeth or gingival tissue. The resin precursor is curable to form a resin selected from the group consisting of Bisphenol A diglycidyl ether dimethacrylate and urethane dimethacrylate. The substrate is pressed against teeth with the teeth pressed into the resin coating. When the resin is partially cured to a shape retaining state, it is removed from the teeth and curing is completed to form a tough flexible material. Alternatively, the substrate may be held against the teeth and the resin precursor may be applied along the teeth-substrate interface with a mixing syringe. High intensity light may be used to cure the resin or enhance catalytic curing. For best results the substrate is made from the same material as is applied to the teeth.

Abstract: An intraoral semi-custom device for the prevention of chronic tension and common migraine headaches and temporomandibular disorders that are caused by chronic clenching of the posterior mandibular and maxillary teeth by the temporalis muscle. The device includes a trough, curved to correspond to the curvature of the maxillary incisors, from which distally extends a dome shape. The trough and dome are formed from a reshapable synthetic resin sheet material. The trough is retained by a cured in place acrylic resin, which is placed into the trough by a dentist and then placed over the maxillary incisors by the dentist. The cured, now substantially rigid, acrylic fits tightly and retains the device around the wearer's upper incisors. Once in place in the wearer's mouth, the dome will come into contact with one or two lower incisor teeth prior to the posterior teeth coming into contact.

Abstract: An intraoral discluding device for the prevention of chronic tension and common migraine headaches and temporal-mandibular joint syndrome that are caused by chronic clenching of the posterior mandibular and maxillary teeth by the temporalis muscle. The discluder is a small intraoral device which is custom made for the individual. The device includes a small, typically acrylic, dome-shaped tab supported by a conventional palatal member which is retained by bent orthodontic wire. The device is inserted in the mouth and retained against the upper anterior teeth with the tab extending such that as the mouth is closed the tab will come into contact with the lower anterior incisal edges before the posterior teeth can touch each other. This renders the temporalis muscles ineffective, preventing high pressure clenching of the posterior teeth.
