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.

Claims

1. An intraoral semi-custom discluding device which comprises:

a prefabricated trough designed to encompass the anterior maxillary incisors;

a dome on said trough extending distally when in a wearer'"'"'s mouth;

said dome configured to contact at least one lower anterior incisor when in place in said wearer'"'"'s mouth prior to any contact between upper and lower posterior teeth; and

a quantity of acrylic resin in said trough molded to conform to the shape of anterior maxillary incisors;

whereby said trough is releasably retained in the mouth by said molded acrylic resin.

2. The device according to claim 1 wherein said trough and dome are fabricated from a synthetic resin.

3. The device according to claim 1 further including a plurality of tabs fastened over said dome to increase the height thereof as desired.

4. The method of preventing the occurrence of chronic tension and common migraine headaches and temporomandibular disorders which comprises the steps of:

providing a device comprising a trough configured to encompass the upper anterior teeth, said trough having a dome that is retained by a resilient material;

filling said trough with an uncured acrylic resin;

fitting said device to a person'"'"'s teeth with said dome extending toward said lower anterior incisors such that dome will contact at least one lower incisor tooth prior to any contact between posterior teeth;

curing said acrylic resin;

placing said device in said person'"'"'s mouth for selected periods.

5. The method according to claim 4 wherein said trough and dome are fabricated from a synthetic resin sheet material.

6. The method according to claim 4 further including the steps of providing a plurality of synthetic resin sheet material tabs and of securing a selected number of tabs in a stacked relationship on said dome to adjust dome height as desired.

7. The method according to claim 4 further including the steps of providing a plurality of synthetic resin sheet material tabs and of securing a selected number of tabs in a stacked relationship on said dome to adjust dome height as desired.

8. A method of manufacturing a device for preventing the occurrence of chronic tension and common migraine headaches and temporomandibular disorders which comprises the steps of:

providing a trough configured to encompass the upper anterior teeth, said trough having a dome projecting therefrom;

filling said trough with an uncured acrylic resin;

fitting said trough to a person'"'"'s teeth with said dome extending toward said lower anterior incisors such that said dome will contact at least one lower incisor tooth prior to any contact between posterior teeth;

curing said acrylic resin;

removing said device from the person'"'"'s mouth.
