  • Patent number: 6171313
    Abstract: An apparatus for use in dental base regeneration has a support bar having fixing members on ends thereof for fixing the bar to teeth of the mandible or maxilla. A bone section engagement member, such as a fork or spade, is connected to a shaft and is inserted into a bone section resulting from osteotomy. A mechanism connects the support member with the shaft for vertical translation of the shaft. Thus, the bone section can be gradually vertically distracted to allow tissue to regenerate and gradually augment the bone ridge of the maxilla or the mandible.

  • Patent number: 5775907
    Abstract: A mandibular distraction device for use in distracting the mandible subsequent to corticotomy thereof includes first and second sets of crowns adapted to be attached to the bicuspid and molar teeth of respective opposite lateral sides of the mandible. A first pair of expander assemblies are removably or fixedly attachable to the opposite sides of the first set of crowns, and a second pair of expander assemblies are removably or fixedly attachable to the opposite sides of the second set of crowns. Each pair of expander assemblies includes one expandable device and one sliding tube assembly. Receptors are provided to be attached to the bicuspid crowns and the molar crowns, and corresponding connectors are provided to be attached to the screw devices and sliding tube assemblies for connection thereof to the crowns.

  • Patent number: 5599183
    Abstract: Mandibular distraction osteogenesis can take place by performing corticotomy surgery at two points on opposite sides of the mandible and at the same time attaching an expansible distraction device to the teeth of the mandible on opposite sides of the two points of the corticotomy surgery. The device is then periodically expanded until a desired mandibular length is obtained. The device includes a plurality of bands that are fitted onto the teeth of the mandible and a number of universal expansion screws that are connected to the bands for purposes of distracting the mandible. This device can be assembled with an appropriate appliance assembly tool that precisely positions and aligns the universal expansion screws relative to the bands during assembly thereof.
