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： A series of medical instruments can be made with the use of shape memory tube with a transformation temperature that is above or below the ambient temperature. In the first case, the material behaves with the shape memory effect and in the second case the behavior is superelastic. The wall of the tube has been provided with a plurality of slots in specific places, often near or at the distal end of the instrument, and in specific arrangements which allow local variations in diameter, shape, and/or length. These variations can either be caused by the memory effect during temperature change or by superelastic behavior during change of the mechanical influences on the memory metal by the surrounding material.

摘要： A method of processing a Ni—Ti—Nb based alloy which contains from about 4 to about 14 atomic percent Nb and in which the ratio of atomic percent Ni to atomic percent Ti is from about 3.8 to 1.2, comprising working the alloy sufficient to impart a textured structure to the alloy, at a temperature below the recrystallisation temperature of the alloy. Preferably, the alloy is worked at least 10%, by a technique such as rolling or drawing, or another technique which produces a similar crystal structure. The alloy has increased stiffness compared with Ni—Ti binary alloys with superelastic properties.

摘要： A method and apparatus for generating a patient treatment plan includes processing that begins by providing a list of health care services to a patient and/or care provider. The processing continues by prompting for input of digital information regarding the patient when health care services applicable to addressing the patient's treatment needs have been concurrently selected. The processing continues by determining whether a sufficient amount of digital information has been received. If so, the processing continues by simulating treatment of a patient based on the digital information, a treatment objective, and normalized patient data. The processing then continues by generating the patient treatment plan in accordance with the simulating of the treatment when the simulated treatment results have been acknowledged.

摘要： A self-ligating orthodontic bracket comprised of a ligating member containing a coil spring segment for extending the ligating member over an archwire or retainer wire and over one or more tie wings to secure the archwire or retainer wire in the bottom of a slot in the bracket. The ligating member containing the coil spring may have ends that are engaged in opposing mesially-distally extending bores in one side of the bracket body, with the ligating member being engaged with one or more tie wings on an opposite side of the bracket body. Alternatively, the ligating member may form a closed loop with the ligating member engaged under both occlusally-projecting and gingivally-projecting tie wings or engaged under one or more tie wings on one side of the bracket body and passing through a mesially-distally extending bore on the opposite side of the bracket body.

摘要： Method and device for fracturing the interface between dental structures that have been secured together, and for adhesive removal and cleaning of the teeth. The device comprises an ultrasonic tool for providing hi-directional movement of a preferred amplitude and frequency. The tool is applied against one of the dental structures at an acute angle with respect to a plane in which the interface between the dental structures lies. Alternatively, the dental tool is applied against the adhesive on the tooth surface for removal thereof. In another alternative, the dental tool is utilized with a liquid layer to provide cavitation of the liquid, thereby cleaning and polishing the enamel surface.
