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.

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 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.
摘要翻译：可以使用具有高于或低于环境温度的转换温度的形状记忆管来制造一系列医疗器械。在第一种情况下，材料表现为形状记忆效应，而在第二种情况下，行为是超弹性的。管的壁在特定位置经常在仪器的近端或远端设置有多个槽，并且具有允许直径，形状和/或长度的局部变化的特定布置。这些变化可以由温度变化期间的记忆效应引起，也可以由周围材料对存储金属的机械影响的改变期间的超弹性行为引起。
