摘要： The present invention relates to a device for performing bone distraction and/or tooth movement, and more particularly to a widening or contracting device which is capable of effecting bone distraction in more than one plane of space simultaneously. In its broadest aspects, the present invention is a device that can be used for bone distraction or osteogenesis, as well as tooth movement, which includes an expandible (or contractible) member for affixation in the oral cavity of a patient. The device is adapted to provide distraction of a selected craniofacial bone, such as the mandible, or movement of teeth, simultaneously in more than one plane of space. The expandible (or contractible) member includes a mechanism for expanding (or contracting) the expandible (or contractible) member to achieve the desired distraction of the selected bone or movement of selected teeth.

摘要： A device and method is presented for enhancing the shape, mass, and strength of alveolar and intramembranous bone, primarily in areas of bony deficit. In one embodiment, the device is made up of a hollow body which forms a housing to contain a drive train and provide a surface for attaching mounting elements. A worm gear activating element which meshes with a threaded lead screw acts as the drive train. A carrier is coupled by threads to the lead screw. As the worm gear is turned, the lead screw rotates and causes the carrier to move along the axis of rotation of the lead screw. In this embodiment, the soft tissue in a region of tooth loss is reflected to expose the atrophic bone site. A piece of bone harvested from the exposed area or other bone attractant material is attached to the carrier. The soft tissue is adapted over the carrier and sutured, and the assembly is attached to available dental structures. After initiation of biological bridging between the harvested bone and the host bone, the drive train is activated to move the carrier. Newly formed bone grows in the path of motion of the carrier between the harvested bone and the underlying bone.

摘要： By using titanium, titanium based alloys, or related metals or alloys, an orthodontic bracket can be manufactured which is lighter and stronger than any conventional type of bracket made of stainless steels, plastics and even ceramics. Ti based brackets have shown excellent corrosion resistance and possess good biocompatibility. Surface treatments including nitriding, diamond coating, pre-oxidation or shot-peening on the slot bottom surface of such brackets reduce the friction coefficient against the orthodontic archwire. Furthermore, the bonding strength may be enhanced by shot-peening, ion beam etching or reactive ion etching on the tooth contact surface of the base portion of the bracket.
