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.

Abstract: Attachment are used with a mandibular distraction device for use in distracting the mandible subsequent to corticotomy thereof. First and second sets of crowns of the device are 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. The attachments include receptor attachments that are provided to be attached to the bicuspid crowns and the molar crowns, and corresponding connector attachments that are provided to be attached to the screw devices and sliding tube assemblies for connection thereof to the crowns.
