bottom tooth 20 as inciated generally at 42 and the free ends are tucked into the respective spacings between the particular bottom tooth 20 and adjacent teeth 20 on each side of the particular tooth 20 the portion of wire 40 which extends between openings 38 is received within slot 36 on the tongue side wire 40 is preferably 0 016 inch stainless steel ligature wire one skilled in the art will appreciate that lateral motion inhibitor appliance 24 described above must be custom fitted to precise dimensions in accordance with the size and shape of each patient 39 s oral cavity for optimum effectiveness for example it has been determined that a clearance of 1 3 mm should be allowed between the curved portion 44 of frame member 26 and the adjacent gumline 46 below bottom teeth 20 at the front of the patient 39 s mouth as illustrated in fig2 each wing member 28 should have a thickness of approximately 2 to 3 mm and a length of approximately 25 35 mm so that each wing member extends from the distal of the first bicuspid to the region of the second molar mandibular appliance 24 is positioned within oral cavity 22 so that each wing member 28a 28b is in contact with only one bottom tooth 20 on each side and has a clearance of approximately 1 mm between major surface 38a and the remaining bottom teeth 20 the corresponding slot 36 is approximately centered with respect to the selected bottom tooth 20 which is in contact with the corresponding wing member 28 so that the ends of wire 40 can be wrapped around.
