## Abstract

An improved mouthguard is provided for use by individuals having orthodontic appliances, such as braces. The mouthguard comprises an outer guard portion and an inner subguard portion. The subguard provides a barrier between the outer guard and the user's braces, thereby allowing the outer guard to be custom fit to the user's mouth and teeth using methods known in the art. Additionally, the subguard is secured to the outer guard, producing a one-piece mouthguard, and allows the mouthguard to be removably secured to the user's braces, increasing the comfort and retention of the mouthguard within the user's mouth. The mouthguard effectively protects the users braces, as well as the user's teeth and mouth, from potential damage arising out impacts suffered by the user during sporting activities while improving the user's comfort and performance in sports by allowing the user to breathe and speak uninhibited during the sporting activity.

## Claims

### Claim 1

A mouthguard comprising:
an outer guard; and
a subguard;
wherein the subguard removably engages orthodontic appliances of an individual, wherein the subguard prevents the outer guard from becoming entangled with the orthodontic appliances, wherein the subguard is mechanically secured to the outer guard, and wherein the subguard includes a at least one ridge, wherein the ridge is embedded within the material from which the outer guard is constructed, and wherein the embedding of the ridge within the material from which the outer guard is constructed mechanically secures the subguard to the outer guard.

### Claim 2 (depends on 1)

The mouthguard of claim 1 wherein the at least one ridge has a triangular cross section and wherein the at least one ridge is a plurality of ridges.

### Claim 3 (depends on 1)

The mouthguard of claim 1 wherein the outer guard is custom fitted to the characteristics of the individual's mouth and teeth.

### Claim 4 (depends on 3)

The mouthguard of claim 3 wherein the outer guard is made of an ethylene vinyl acetate copolymer.

### Claim 5 (depends on 1)

The mouthguard of claim 1 wherein the subguard is made of a medical-grade plastic.

### Claim 6 (depends on 1)

The mouthguard of claim 1 wherein the subguard includes at least one extension that extends from a distal surface of the subguard and wherein the at least one extension removably engages the orthodontic appliances of the individual.

### Claim 7 (depends on 6)

The mouthguard of claim 6 wherein the at least one extension comprises an extension arm that extends from the distal surface of the subguard.

### Claim 8 (depends on 6)

The mouthguard of claim 6 wherein the at least one extension comprises an extension arm that extends from the distal surface of the subguard and a tip that is connected to the extension arm opposite the distal surface of the subguard.

### Claim 9 (depends on 8)

The mouthguard of claim 8 wherein the tip of the extension has a substantially spherical shape.

### Claim 10 (depends on 9)

The mouthguard of claim 9 wherein extension arm of the at least one extension is flexible and allows the extension to have a deflected configuration wherein the mouthguard may be removed from the mouth of the individual and a resting configuration wherein the extension removably engages the individual's orthodontic appliances.

### Claim 11 (depends on 6)

The mouthguard of claim 6 wherein the at least one extension comprises a plurality of extensions.

### Claim 12 (depends on 11)

The mouthguard of claim 11 wherein the plurality of extensions extend in pairs from the distal surface of the subguard.

### Claim 13 (depends on 12)

The mouthguard of claim 12 wherein the plurality of extensions are laterally spaced from each other and the lateral spacing of the extensions correspond with the lateral spacing of the orthodontic appliances of the individual.
