An oral appliance, a system and a method for correcting malocclusions may cause teeth and/or jaws of the patient to move into a corrected position. An upper body and a lower body of the appliance may be connected by a hinge. Lingual protrusions may extend rearward from the anterior portion of the upper body and contact the maxilla of the patient when the appliance is worn. A protrusion may extend from the anterior portion of the lower body forward relative to the mouth and contact the lips and exert a rearward force against the lower teeth.

1. An appliance for correcting a malocclusion in a mouth of a user, the appliance comprising: a generally U-shaped upper body having an anterior portion configured to be adjacent to upper incisors and a posterior portion located rearward to the anterior portion, the upper body having an upper base with a perimeter defining an outer boundary and walls extending along the perimeter of the posterior portion of the upper body;a generally U-shaped lower body having an anterior portion configured to be adjacent to lower incisors, the lower body having a lower base with a perimeter defining an outer boundary, the lower base having a width which is configured to be greater than a width of the teeth of the user and wherein the lower body has walls extending along the perimeter of the lower body to define a trough, the trough being configured to contact the lower incisors as the appliance is worn in the mouth of the user;lingual protrusions extending rearward from the anterior portion of the upper body, the lingual protrusions being configured to contact a maxilla when the appliance is worn within the mouth of the user; anda bumper that is configured to define a labially enlarged area with respect to the outer boundary across a labial portion of the anterior portion of the lower body of the appliance so that a rearward force is configured to be exerted by the lips of the user against the bumper and cause a lower jaw of the user to move rearward relative to an upper jaw of the user as the lower appliance is worn within the mouth of the user. 2. The appliance of claim 1 further comprising: a raised surface on the posterior portion of the upper base of the upper body. 3. The appliance of claim 1 further comprising: a shelf that projects generally horizontally from the upper body, the shelf being adjacent to the upper anterior base and being configured to extend rearward in the mouth of the user to provide a surface that is configured to guide a tongue as the appliance is worn within the mouth of the user. 4. The appliance of claim 1 further comprising: a ramp that extends at an angle relative to the upper base on the anterior portion of the upper body, the ramp being configured to exert a force on the upper incisors and guide the upper incisors forward and downward as the appliance is worn within the mouth of the user. 5. The appliance of claim 1 wherein the upper base is configured to contact the furthest forward upper teeth within the mouth. 6. The appliance of claim 1 further comprising: a raised protrusion on one of the lingual protrusions, the raised protrusion being configured to direct a tongue as the appliance is worn within the mouth of the user. 7. The appliance of claim 1 further comprising: a reline material in contact with the trough in the lower body, the reline material being configured to adhere the lower body to lower teeth and to exert a force against the lower teeth to thereby cause the lower teeth to move rearward as the appliance is worn in the mouth of the user. 8. The appliance of claim 1 wherein the appliance is constructed from a resilient material. 9. The appliance of claim 1 wherein the trough has a roughened surface. 10. The appliance of claim 1 wherein the lingual protrusions have a center tab extending rearward from a center of the anterior portion of the upper body and a side tab adjacent to each side of the center tab and extending rearward from the anterior portion of the upper body, the center and side tabs being configured to move the maxilla and upper teeth forward with respect to the mouth in response to pressure from a tongue. 11. The appliance of claim 10 wherein the side tabs are configured to encourage the tongue to exert pressure against the palatal tabs to encourage a widening of the palate. 12. The appliance of claim 1 further comprising palatal tabs on the posterior portion of the upper body, the palatal tabs being configured to receive pressure exerted by a tongue to encourage a widening of the palate. 13.
