The teeth engaging member 5 defines upper and/or lower dental arch receiving channels 46, 47 and is made of a resiliently flexible material that is deformable. The appliance 1 has a resting form in which the resilient materials of the base member 2 and the teeth engaging member 5 are in their resting condition. The appliance 1 can be flexed or deformed out of the resting form to fit the underdeveloped dental arch form into the dental arch receiving channel 46, 47. When deformed the appliance 1 exerts a return force that urges the underdeveloped dental arch to expand.Type: GrantFiled: January 31, 2012Date of Patent: June 11, 2013Inventor: Christopher John Farrell

Patent number: 8453650Abstract: A mouthpiece includes a first body configured to be secured over one or more teeth of a user. The first body comprises a frame for location about at least one of a molar or a premolar of user, as a first bite pad between upper teeth and lower teeth. The first bite pad is molded in the frame while in situ in the mouth of the user and the first bite pad is formed by a PVS material. The first bite pad is in contact with at least one of a molar or a premolar of user, and the first bite pad defines an exterior shape of at least a portion of the teeth of a user. There is a similar second body with a connector between the first body and the second body and together these form the appliance for the user.Type: GrantFiled: July 3, 2012Date of Patent: June 4, 2013Assignee: MDMInventor: David Scott Frey
