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 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： A self-ligating bracket with flexible ligating slide includes an archwire slot, a first anterior portion at a first side of the slot, and a second anterior portion at a second side of the slot, the second anterior portion including a primary anterior surface. The bracket includes a first guide and a second guide, with each of the guides extending anteriorly from the primary anterior surface. The slide is movably enclosed between the primary anterior surface, the first guide, and the second guide. At least one of the primary anterior surface, first guide, and second guide includes a curvature in an occlusal-gingival direction. The curvature includes a radius and a center, with the center located to one side of a plane that bisects the slot longitudinally. The plane is perpendicular to a slot bottom wall; and the one side of the plane is the side that includes the second anterior portion.
