Abstract
Abstract A pressure sensitive mouth piece has a pressure detector-sound unit assembly mounted on or embedded in the molded bite guard. When a patient clenches or bruxes his teeth, the pressure detector senses that condition and activates the sound unit to emit a tone audible to the patient. The patient is thereby alerted that he is clenching or bruxing his teeth so he can stop. Alternatively, a mechanical clicker can be embedded in the mouth piece and will emit an audible tone when the patient clenches or bruxes his teeth.

Claims Analysis
Total Claims: 31
Claim 1
Independent Claim
71 words
A pressure sensitive mouth piece comprising: (a) a premolded bite guard means to be worn between a patient's upper and lower teeth for preventing contact between the patient's upper and lower teeth; and (b) means attached to the bite guard means and directly responsive to pressure from the patient's teeth for emitting a tone audible to the patient when the patient grinds his teeth and exerts pressure on the bit guard.
Claim 2
Dependent Claim
71 words
A pressure sensitive mouth piece comprising: (a) a premolded bite guard means to be worn between a patient's upper and lower teeth for preventing contact between the patient's upper and lower teeth; and (b) means attached to the bite guard means and directly responsive to pressure from the patient's teeth for emitting a tone audible to the patient when the patient grinds his teeth and exerts pressure on the bit guard.
Claim 3
Dependent Claim
15 words

Claim 5
Dependent Claim
53 words
The pressure sensitive mouth piece of claim 1 wherein the means for emitting a tone comprises: (a) a pressure detector; and (b) a sound unit connected to the pressure detector whereby when a patient grinds his teeth the pressure detector is activated to effect the audible tone to emit from the sound unit.
Claim 6
Dependent Claim
39 words
The pressure sensitive bite guard of claim 4 wherein the sound unit comprises: (a) a speaker means; (b) an integrated circuit means for activating the speaker means; and (c) a power supply means for powering the integrated circuit means.
Claim 7
Dependent Claim
26 words
The pressure sensitive mouth piece of claim 4 wherein the pressure detector and the sound unit are each attached to a surface of the bite guard.
Claim 8
Dependent Claim
23 words
The pressure sensitive bite guard of claim 4 wherein the pressure detector and the sound unit are each embedded within the bite guard.
Claim 9
Dependent Claim
81 words
A pressure sensitive mouth piece comprising: (a) a bite guard adapted to be worn over a patient's teeth, and (b) a pressure detector embedded in the bite guard, (c) a pressure detector comprising a mechanical member having a fixed upper arm joined to a movable lower arm, said movable lower arm having a bend point whereby when the patient clenches or bruxes, the movable lower arm flexes about the bend causing an audible click that can be detected by the patient.
Claim 10
Dependent Claim
81 words
A pressure sensitive mouth piece comprising: (a) a bite guard adapted to be worn over a patient's teeth, and (b) a pressure detector embedded in the bite guard, (c) a pressure detector comprising a mechanical member having a fixed upper arm joined to a movable lower arm, said movable lower arm having a bend point whereby when the patient clenches or bruxes, the movable lower arm flexes about the bend causing an audible click that can be detected by the patient.
Claim 11
Dependent Claim
27 words
The pressure sensitive mouth piece of claim 8 wherein the fixed upper arm is slightly concave to provide a sound chamber whereby the audible click is amplified.
Claim 12
Dependent Claim
89 words
A pressure sensitive mouth piece comprising: (a) a bite guard means to be worn between a patient's upper and lower teeth for preventing contact between the patient's upper and lower teeth; (b) a pressure detector attached to the bite guard means; and (c) a sound unit attached to the bite guard means and connected to the pressure detector whereby when a patient clenches or bruxes his teeth the pressure detector senses that condition and activates the sound unit to emit an audible tone which is perceptible to the patient.
Claim 13
Dependent Claim
89 words
A pressure sensitive mouth piece comprising: (a) a bite guard means to be worn between a patient's upper and lower teeth for preventing contact between the patient's upper and lower teeth; (b) a pressure detector attached to the bite guard means; and (c) a sound unit attached to the bite guard means and connected to the pressure detector whereby when a patient clenches or bruxes his teeth the pressure detector senses that condition and activates the sound unit to emit an audible tone which is perceptible to the patient.
