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 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 a health care service has been 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 method and apparatus for generating a three-dimensional digital model of a desired orthodontic structure include processing that begins by obtaining a three-dimensional model of an actual orthodontic structure, wherein the three-dimensional digital model is defined in x, y, z space. The processing then continues by generating an interim three-dimensional model of the desired orthodontic structure less teeth. The interim three-dimensional model is designed in x, y, z space and includes the desired placement of an occlusal plane, an upper-arch form, a lower-arch form, an upper-arch midline, and a lower- arch midline. The processing then continues by positioning the upper and lower teeth with respect to the interim digital model and the defined x, y, z space to obtain a first pass three-dimensional digital model of the desired orthodontic structure. The processing continues by determining whether achieving the first pass three-dimensional model is feasible. When achieving the first pass three-dimensional image is feasible, the processing continues by utilizing the first pass three-dimensional model as the desired three-dimensional digital model.

摘要： A method and apparatus for simulating tooth movement for an orthodontic patient include processing that begins by determining, on a tooth by tooth basis, a three-dimensional direct path of movement from a three-dimensional digital model of an actual orthodontic structure and a three-dimensional digital model of a desired orthodontic structure. The processing continues by simulating tooth movement for a plurality of teeth based on each tooth's corresponding three-dimensional direct path. The process then determines whether a conflict arises between at least two teeth of the plurality of teeth, or for a single tooth, during the simulating. If a conflict arose between at least two teeth, the conflict is resolved with respect to a priority tooth of the teeth in conflict.
