An orthodontic arch expander joins to a mouthpiece proximate to the rear of the mouthpiece. The transparent mouthpiece has a desired arc that fits over the teeth of the upper jaw. The mouthpiece has two wings that join near the incisors and then become parallel and spaced apart around the molars. Near the molars, an arch expander joins to the mouth piece. The arch expander has two telescoping shells with a threaded jack and cooperating springs. Each shell joins to a corresponding wing of the mouthpiece. Turning the jack lengthens a rod that pushes the shells outwards against the mouthpiece thus widening the maxillary arch without brackets or bands upon the teeth. An alternate embodiment has the arch expander attaching directly to the palatal bone through screws placed through a grommet at the end of each shell by an orthodontist or oral surgeon.

I claim: 1. A device for incrementally widening the maxillary arch of the jaw of a person, said device adapting to rest upon the teeth of the maxillary arch without mechanical bands or adhesive bonds, and said device further comprising: a transparent mouthpiece having two wings placing over all of the teeth of said jaw each of said wings having a generally U shaped cross section; a housing having a generally hollow rectangular cross section including a top and an opposite bottom and two spaced apart and mutually parallel sidewalls, and said housing fusing by heat or chemical welding upon at least one of said top, said bottom, and said sidewalls to one of said wings upon the interior of the U shaped cross section; an advancing member having a generally hollow rectangular cross section of lesser dimension than said housing including a top and an opposite bottom and two spaced apart and mutually parallel sidewalls, and said advancing member fusing by heat or chemical welding upon at least one of said top, said bottom, and said sidewalls to the other of said wings upon the interior of the U shaped cross section and said advancing member extending telescopically in opposition to said housing; a threaded rod being generally centered in said device, turning and separating said housing outwards from said advancing member laterally within said maxillary arch; and, a pair of cooperating springs being parallel to said threaded rod and providing expansive force upon said housing and said advancing member thus easing turning of said threaded rod, and locating within said advancing member. 2. The device of claim 1 wherein said housing and said advancing member are located proximate to where said device fits upon the molars of said person. 3. A device for incrementally widening the maxillary arch of the jaw of a person, said device adapting to secure to palatal bone generally forming the roof of the mouth of said person, said device further comprising: a housing having a generally hollow rectangular cross section including a back wall and an opposite open front, a top and an opposite bottom and two spaced apart and mutually parallel sidewalls, and one grommet extending perpendicular to said back wall, said grommet having a hole locating upon the axis of the threaded rod; and, an advancing member having a generally hollow rectangular cross section of lesser dimension than said housing including a back wall and an opposite open front, a top and an opposite bottom and two spaced apart and mutually parallel sidewalls, telescoping from within said front of said housing and one grommet extending perpendicular to said back wall, said grommet having a hole therethrough locating upon the axis of the threaded rod; at least two fasteners, said fasteners being placed through said holes in said grommets and adapting to insert into the palatal bone for securing said device to the person; and, a threaded rod being generally centered in said device, turning and separating said housing outwards from said advancing member laterally within said maxillary arch; and, a pair of cooperating springs being parallel to said threaded rod and providing expansive force easing turning of said threaded rod and biasing said advancing member and said housing outwardly; whereby, turning said threaded rod separates said housing outwards from said advancing member laterally within said maxillary arch, widening the maxillary arch of a person's jaw. 4. The device of claim 3 further comprising: said grommet upon said housing being parallel to the length of said housing and said hole through said grommet admitting said fastener perpendicular to the length of said housing; and, said grommet upon said advancing member being parallel to the length of said advancing member and said hole through said grommet admitting said fastener perpendicular to the length of said advancing member. 5. The device of claim 3 further comprising: said grommet upon said housing being bent to fit the surface of the palatal bone and said hole through said grommet admitting said fastener perpendicular to the length of said housing; and, said grommet upon said advancing member being bent to fit the surface of the palatal bone and said hole through said grommet admitting said fastener perpendicular to the length of said advancing member.
