Abstract

An orthodontic appliance for assisting in properly positioning teeth within the mouth of an individual which is capable of fitting various mouth and tooth sizes. The appliance includes a labial-buccal flange, a lingual flange spaced from the labial-buccal flange, both of which define a generally U-shaped configuration in the occlusal view, and an isthmus interconnecting the two flanges. At least one tooth trough is defined between the labial-buccal flange and the lingual flange for receiving either an upper or a lower row of the individual'"'"'s teeth. The appliance includes no individual tooth sockets but instead utilizes pressure applied by the labial-buccal flange, the lingual flange, and the relative angles and material thicknesses to properly position the teeth. The appliance is capable of fitting mouths and teeth of various sizes because it includes no individual tooth sockets. The appliance is also useful as a device for preventing sleep apnea, snoring and bruxism as well as an athletic mouth guard.

20. The orthodontic appliance of claim 4 wherein said inner lingual surface of one of said maxillary tooth receiving trough and said mandibular tooth receiving trough tapers away from said inner labial surface such that said orthodontic appliance laterally accommodates in said incisor area at least part of a canine tooth of a mouth of a larger person or a whole canine tooth of a mouth of a smaller person.

21. The orthodontic appliance of claim 20 wherein said inner lingual surface tapers away from said inner labial surface on the other of said maxillary or mandibular tooth receiving troughs such that said orthodontic appliance accommodates at least part of a canine tooth of a mouth of a larger person or a whole canine tooth of a smaller person.

22. The orthodontic appliance of claim 4 further comprising one or more air passageways formed transversely through said isthmus extending between said lingual flange and said labial-buccal flange.
