Abstract

Abstract A mouthpiece according to the teachings of the present invention is shown as including a lens-like brace integrally formed in the outer upstanding portion of the elongated shell and positioned on the outer surface of the anterior teeth for reflecting any blow to the anterior teeth and reducing the shock to the teeth. The mouthpiece further includes a thickened connecting portion overlying the biting surface of the posterior teeth to help prevent concussion and to lessen the shock to the Tempro Mandibular Joint in the event of a blow to either the jaw or head. Indentations are formed in the thickened connecting portion opposite to the biting surfaces of the user's upper teeth having a size and shape complementary to and for receiving the user's lower teeth to form an occlusal index for positioning the user's lower teeth helping to eliminate the trauma of a blow to the side of the jaw. The inner upstanding portion of the mouthpiece terminates in a palate area which does not substantially overlie the user's hard palate to help eliminate activating the gag reflex.

Claims Analysis

Total Claims: 19
Claim 1
Independent Claim 150 words
Protective mouthpiece positioned on the user's teeth, with the user having anterior and posterior teeth, with the teeth having outer, inner, and biting surfaces, comprising, in combination: an elongated shell of flexible, shock absorbing polymeric material having an essentially U-shaped cross section defined by inner and outer upstanding portions and a connecting portion, the shell being arcuately formed over its length to fit over a row of teeth including the anterior and prosterior teeth, said outer and inner upstanding portions and said connecting portion adapted to respectively overlie and directly engage the outer, inner and biting surfaces of the user's teeth; and a protruding rib-like brace located on the outer upstanding portion of the elongated shell opposite the outer surface of the anterior teeth and intermediate the upper and lower extremities of said upstanding portion for reflecting any blow to the anterior teeth and reducing the shock to the teeth.
Claim 2
Dependent Claim 150 words
Protective mouthpiece positioned on the user's teeth, with the user having anterior and posterior teeth, with the teeth having outer, inner, and biting surfaces, comprising, in combination: an elongated shell of flexible, shock absorbing polymeric material having an essentially U-shaped cross section defined by inner and outer upstanding portions and a connecting portion, the shell being arcuately formed over its length to fit over a row of teeth including the anterior and prosterior teeth, said outer and inner upstanding portions and said connecting portion adapted to respectively overlie and directly engage the outer, inner and biting surfaces of the user's teeth; and a protruding rib-like brace located on the outer upstanding portion of the elongated shell opposite the outer surface of the anterior teeth and intermediate the upper and lower extremities of said upstanding portion for reflecting any blow to the anterior teeth and reducing the shock to the teeth.
Claim 3
Dependent Claim 74 words
The protective mouthpiece of claim 1 wherein the shell has a shape complementary to and to cover all of the anterior and posterior teeth, wherein the connecting portion of the shell overlying the biting surfaces of the posterior teeth has a thickness which is greater than the thickness of the remaining portions of the elongated shell, wherein the thickened connecting portion helps to prevent concussion and lessens the shock to the Tempro Mandibular Joint.
Claim 4
Dependent Claim 49 words
The protective mouthpiece of claim 2 further comprising, in combination: an occlusal index formed on the thickened connecting portion opposite to the biting surfaces of the user's upper teeth for positioning the user's lower teeth helping to eliminate the trauma of a blow to the side of the jaw.
Claim 5
Dependent Claim 46 words
The protective mouthpiece of claim 3 wherein the occlusal index comprises, in combination: indentations formed in the thickened connecting portion opposite to the biting surfaces of the user's upper teeth having a size and shape complementary to and for receiving the lower teeth of the user.
Claim 6
Dependent Claim 37 words
The protective mouthpiece of claim 3 wherein the inner upstanding portion of the elongated shell terminates in a reduced palate area which does not substantially overlie the user's hard palate to help eliminate activating the gag reflex.
Claim 7
Dependent Claim 17 words
The protective mouthpiece of claim 1 wherein the brace has a generally isosceles triangular shaped cross section.
Claim 8
Dependent Claim 22 words
The protective mouthpiece of claim 1 wherein the brace covers approximately 5/8 of the outer surface of each of the anterior teeth.
Claim 9
Dependent Claim 22 words
The protective mouthpiece of claim 1 wherein the brace is integral and incorporated into the outer upstanding portion of the elongated shell.
Claim 10
Dependent Claim 24 words
The protective mouthpiece of claim 1 wherein said polymeric material becomes conformably flexible at elevated temperatures to permit molding thereof into a desired shape.
Claim 11
Dependent Claim 16 words
The protective mouthpiece of claim 1 wherein said elongated shell is formed of Ethyl Vinyl Acetate.
Claim 12
Dependent Claim 56 words
The protective mouthpiece of claim 1 wherein the shell has a shape complementary to and to cover all of the anterior and posterior teeth; and wherein the inner upstanding portion of the elongated shell terminates in a reduced palate area which does not substantially overlie the user's hard palate to help eliminate activating the gag reflex.
Claim 13
Dependent Claim 52 words
The protective mouthpiece of claim 1 further comprising, in combination: a strap having a first end connected to the mouthpiece and a second end including means for releasably interconnecting the strap to an athletic helmet for releasing the strap in the event that the athletic helmet is torn from the user's head.
Claim 14
Dependent Claim 98 words
The protective mouthpiece of claim 12 wherein the releasably interconnecting means comprises, in combination: first and second locking arms extending on opposite sides of the second end of the strap; slots formed in the strap intermediate its first and second ends for receiving the second end of the strap with the locking arms abutting with the strap around the slots; and a removed portion formed in the second end of the strap intermediate the first and second locking arms allowing the first and second locking arms to flex together and be pulled through the slots of the strap.
Claim 15
Dependent Claim 44 words
The protective mouthpiece of claim 13 wherein the first end of the strap is connected to the inner upstanding portion of the shell such that the strap extends over the connecting portion of the shell and does not raise the lip of the user.
