  • Publication number: 20190309712
    Abstract: A valve for metering a fluid is described, which is used, in particular, as a fuel injector for internal combustion engines, including an electromagnetic actuator and a valve needle actuatable by the actuator, an armature of the actuator being guided on valve needle, a stop element which limits a movement of the armature relative to the valve needle being situated on the valve needle, and the armature including a spring receptacle which is open toward the stop element and in which a spring supported on the stop element is inserted. The valve needle is guided via the armature and/or the stop element along a longitudinal axis of a housing. Furthermore, as viewed along the longitudinal axis, a length of the spring receptacle is smaller than a spring length of the spring in the non-actuated initial state.

  • Patent number: 10058400
    Abstract: A green metal body includes metal particles and a binder in the shape of an orthodontic bracket and/or base plate. The green metal body is fabricated by being laser-cut with a laser to shape the green metal body into the shape of an orthodontic bracket and/or to carve recesses and/or undercuts into the bonding surface of the bracket. The green metal body is sintered to shrink its volume into a denser and less porous sintered metal body configured to be an orthodontic bracket. The resultant sintered orthodontic bracket includes recesses and/or undercuts in the bonding surface to provide a mechanical aspect when bonded to a tooth.

  • Patent number: 9877805
    Abstract: A method of shaping a green body provides a shaped green body comprised of a plurality of sinterable particles and an organic binder. Such a method includes: (1) molding a mixture of sinterable particles and organic binder into the shape of an initial green body or intermediate, wherein the sinterable particles include at least one of metal particles or ceramic particles; and (2) shaping the green body intermediate with at least one of a stream of energy or a stream of matter, wherein the shaping yields a green body having a desired shape. The shaped green body can be sintered in order to provide a hardened body having substantially the shape of the shaped green body.

  • Patent number: 7857618
    Abstract: Orthodontic brackets include a bracket base, at least one arch wire slot formed in the base adapted to receive an arch wire therein, and a moveable structure for selectively narrowing the width of at least a portion of the arch wire slot so as to allow for engagement of an undersized arch wire having a width less than the slot width. The moveable structure for selectively narrowing the width of the arch wire slot may be defined by one or more spaced apart cuts disposed in at least one side wall defining the arch wire slot so as to define a bendable portion of the sidewall.

  • Patent number: 7611352
    Abstract: An orthodontic bracket system including a plurality of interchangeable ligation covers so as to allow the patient and practitioner to create a desired aesthetic look. The inventive orthodontic bracket system includes a bracket base, at least one arch wire slot formed in the bracket base adapted to receive an arch wire therein, a first interchangeable ligation cover that when releasably assembled to the bracket base can be selectively moved relative to the bracket base between an open non-ligating position relative to the arch wire slot and a closed, ligating position relative to the arch wire slot, and a second interchangeable ligation cover of a different color and/or formed of a different material relative to the first cover. The interchangeable ligation covers can be removed and replaced with another cover of a different color and/or different material to create a different aesthetic appearance.

  • Patent number: 7458811
    Abstract: A bite ramp includes a tooth-attachment element and ramp element. The tooth-attachment element is sized and configured for bonding to the lingual surface of a person's tooth, while the ramp element may be either fixed or else hingedly or bendably adjustable relative to the tooth-attachment element. The ramp element provides a ramp at a desired angle for engaging a corresponding tooth of the opposite dental arch when the person's mouth is closed. The engagement between the ramp element and the corresponding tooth of the opposite dental arch may cause the lower jaw to move forward, rearwardly, or not at all relative to the upper jaw, thereby incrementally correcting a deep bite or other abnormal orthodontic condition. A kit may be provided that includes multiple bite ramps, at least two of which initially include different ramp angles.

  • Publication number: 20080241782
    Abstract: Two-piece self-ligating orthodontic brackets including a bracket base, at least one arch wire slot formed in the bracket base adapted to receive an arch wire therein, and a ligation cover that is hingedly attachable to the bracket base. The bracket further includes means for resisting lateral movement of an occlusal front portion of the ligation cover so as to guide the occlusal front portion of the cover as the cover is closed over the bracket base. For example, the bracket base may include a pair of spaced apart guides which extend from the base in a labial-buccal direction so as to define a receiving cavity between the guides. The cover includes a corresponding occlusal front nose portion which is configured to be received within the receiving cavity when the cover is closed.
