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. This renders the temporalis muscles ineffective, preventing high pressure clenching of the posterior teeth, thus preventing tension headache, common migraine, and temporomandibular disorders. While the device may be worn most of the time, including during sleep, it is not attached permanently and is always removed while eating, thus preventing supraeruption of the posterior teeth.
