Intraoral appliance and method of treating patient
First Claim
1. An intraoral appliance comprising proximity detector means for sensing the relative positon of body parts in the oral cavity and signal means connected with the detector for signaling when body parts in the oral cavity are in an undesirable position, said signal means including time delay means for delaying a signal until the body parts have been in an undesirable position for a predetermined length of time.

Abstract
An intraoral device makes a new treatment of dental problems possible. The device includes electronic circuitry to sense unwanted or undesirable relative positions of body parts within the oral cavity. The undersirable position may be teeth clenched, jaw open with teeth unclenched, tongue pressed against teeth or a retruded position of the lower jaw. When these positions have been assumed for too long, a signal reminds the patient. This automatic signal makes it possible for the patient to unlearn bad habits or learn new habits. The dentist may then treat the dental problems caused by the bad habit in a conventional way, knowing that because the habit is broken, recurrence of the dental problem is unlikely. The circuitry includes a proximity detector, a variable time delay and signal generator along with a power supply. When tongue thrusting is to be treated a cage is mounted in the mouth almost against the inside of the front teeth. Tongue contact moves the cage forward actuating the proximity detector.

- 16. A method of treating a patient comprising the steps of placing a proximity sensing and signaling device entirely within the patient'"'"'s oral cavity, sensing when body parts in the patient'"'"'s oral cavity are in an undesirable position and signaling the patient whereby the patient, being aware of the undesirable proximity, may voluntarily move the body parts to a more favorable position, the step of signaling including the step of delaying the signaling until after the body parts have been in the undesirable position for a predetermined length of time.
-
22. A method of treating a patient comprising the steps of sensing when body parts in the oral cavity have been in an undesirable position for longer than a predetermined time, distinguishing between momentary and prolonged undesirable positioning of the body parts, and signaling the patient in response to prolonged undesirable positioning of the body parts whereby the patient may voluntarily move the body parts to a more favorable position.
- 23. An intraoral appliance comprising proximity detector means for sensing the relative position of body parts in the oral cavity, signal means connected with the detector for signaling when body parts in the oral cavity are in an undesirable position, cage means connected with the proximity detector means for sensing the position of the tongue, the cage means being forwardly movable in response to forward movement of the tongue, biasing means including a spring for urging the cage rearwardly, and splint means for engaging teeth, the splint means containing the signal means, the cage means being forwardly and rearwardly movable with respect to the splint means, and the splint means including two portions, each adapted to engage teeth on a different side of the oral cavity.
-
28. A method of treating a patient comprising the steps of placing a proximity sensing and signaling device entirely within the patient'"'"'s oral cavity, sensing when body parts in the patient'"'"'s oral cavity are in an undesirable position and signaling the patient whereby the patient, being aware of the undesirable proximity, may voluntarily move the body parts to a more favorable position, the step of signaling including signaling after mandibular and maxillar tooth have been spaced apart by more than a predetermined distance for more than a predetermined length of time.
