  • Patent number: 7357635
    Abstract: A method and apparatus are provided for changing the form of the jaw and facial bones of an adult patient that did not develop fully during childhood. The method utilizes a device having a plate body with an expansion screw that fits within the mouth of the patient; flap springs that project from the plate body, and an overlay extending from the plate body. The device is placed within the mouth of the patient so that the overlay is in a position between at least two opposing teeth. In this position, opposing teeth contact the overlay during function (e.g. swallowing). This intermittent, unilateral application of force to the facial bones causes these bones to further develop, positioning out of place teeth into more proper positions, and inducing a more symmetrical and enhanced appearance of the face, as well as increasing the airway space behind the jaws. Concomitantly, the flap springs gently press against selected teeth that are out of alignment in order to guide those teeth into place.

  • Patent number: 5885283
    Abstract: An apparatus and method to elongate and extend outward and downward a surgically transected forward section of the mandible with small daily adjustments to stretch the filamentary connective tissue between the divided sections of bone to correct severe malocclusion. The apparatus maintains a narrow gap between the separated sections of the mandible as the connective tissue is lengthened and mineralized forming new bone. The slowly widened gap has a chance to create new bone forming tissue to bridge the gap. By containing the apparatus within the oral cavity, advantages over cumbersome external apparatus become apparent. Infection and inflammation are easier to control within the oral environment. By clamping the apparatus to the ramus under the masseter muscles, no external facial scars result from externally applied surgical pins. Separate adjustments independently move the transected section of the mandible outward and downward.

  • Patent number: 5752953
    Abstract: An osteotomy procedure for adjusting the conformation of a long-bone is described. Illustratively, a proximal tibial osteotomy procedure produces two relatively rotatable long-bone segments. A jig including a body and having two pins extending therefrom in the same direction in a plane containing the long axis of the jig preferably is used to adjustably fix the two segments relative to one another with each pin securely fixed within a corresponding one of the segments. Importantly, at least the distal pin is bendable such that a desired rotation with two degrees of freedom is achievable between the two to-be-fixed segments. By bending the distal pin in a region thereof extending between the jig body and the distal segment, any desired relative rotation may be achieved between the segments. Correction of any and all conditions including varus, valgus, internal and external rotation may be accomplished in a single osteotomy procedure.
