## Abstract

An oral expansion device comprises a first body, main body and a second body wherein the first body and second body are attached to a body and a first tube and a second tube wherein the first tube and second tube having one end attached to the body and having a second end attached to an inflation device. The first tube can be attached internally to the first cavity to the inflate or deflate it and the second tube can be attached internally to the second cavity to inflate or deflate it. The body is manufactured from a flexible material. The first cavity and the second cavity can be manufactured from an inflatable material. The first cavity is an oval and the second cavity is a rectangular shape. The body has a 35-degree bend wherein the second cavity is centered on the 35-degree bend and the body can have two depressions on its sides.

## Claims

### Claim 1

An oral expansion device for a patient having a mouth with teeth and an interior surface with skin opposite to the interior surface, the device comprising:
a semi-rigid main body having a length, a tooth side defining a length, and a cheek side, the main body configured to be inserted into a position with the length of the tooth side abutting the teeth between the teeth and the inner surface of the patient's mouth; and
a first body mounted on the main body opposite the tooth side such that the first body resides between the main body and the interior surface when the main body is in the position, wherein the first body has a first expanding surface that mechanically or through changes in pressure is configured to expand such that if the main body were in the position the outside surface of the first body presses against the interior surface away from the patient's teeth to stretch the patient's skin.

### Claim 2 (depends on 1)

The oral expansion device according to claim 1, further comprising a second body having a second expanding surface wherein the first body and the second body can inflate and deflate by a pump.

### Claim 3 (depends on 2)

The oral expansion device according to claim 2, wherein the pump is a manual or powered pump.

### Claim 4 (depends on 3)

The oral expansion device according to claim 3, wherein the change in pressure is caused by a first tube and a second tube which are connected to the first body and the second body wherein the first tube and second tube opposing ends are connected to the pump which inflates or deflates the first body and the second body.

### Claim 5 (depends on 2)

The oral expansion device according to claim 2, wherein the first body and second body are manufactured from material such as polyvinyl, TPU, rubber or polymer.

### Claim 6 (depends on 1)

The oral expansion device according to claim 1, wherein the main body is manufactured from biocompatible materials configured to form to the patient's mouth.

### Claim 7 (depends on 1)

The oral expansion device according to claim 1, wherein the first body and main body are manufactured from material such as plastic, polyvinyl, TPU, rubber or polymer.
