Vibrational oral appliance with mandibular advancements

An oral appliance comprising:

• an upper tray configured to be positioned over an upper dental arch of a patient;
• and
• a lower tray configured to be positioned over a lower dental arch of the patient;
• wherein a first adjustable positioner and a second adjustable positioner each individually comprise a screw mechanism coupled to a spacer, wherein each screw mechanism is configured to set a position of the spacer to which it is coupled;
• wherein the position of the spacer provides a desired amount of mandibular advancement when the first and second adjustable positioners engage with the first and second fans, respectively;
• wherein the upper tray and the lower tray each individually comprise at least one axial spring configured to contact a palatal/lingual surface of at least one tooth, wherein the at least one axial spring of the upper tray and the at least one axial spring of the lower tray are each individually coupled to the respective lower tray or upper tray, wherein the at least one axial spring of the upper tray and the at least one axial spring of the lower tray are each individually configured to produce and transmit intermittent, cyclic forces to the palatal/lingual surface of the at least one tooth;
• and
• wherein the upper tray and the lower tray each individually comprise at least two sections coupled by an expansion mechanism to enable adjustment of the size of the upper tray and the lower tray to account for palatal expansion and upper and lower jaw development.
