    • An orthodontic bracket for coupling an archwire with a tooth includes a bracket body that has an archwire slot adapted to receive the archwire. A movable member is engaged with the bracket body and is movable between an opened position and a closed position. The bracket body and the movable member may be made from a transparent or translucent polycrystalline ceramic for improved aesthetics. The polycrystalline ceramic has a grain size distribution characterized by an average grain size in the range of larger than 3.4 μm to about 6 μm. The polycrystalline ceramic may have a fracture toughness of at least 4.0 MPa·m1/2. The grain size distribution may not be characterized as a lognormal distribution and may be a multimodal distribution. The polycrystalline ceramic may comprise aluminum oxide or alumina. The grain size distribution may be characterized by having up to about 50% of the grains being less than about 3 μm in size. The grain size distribution may be characterized by having up to about 90% of the grains being less than about 10 μm in size.
    • 用于将弓丝联接到牙齿的正牙支架包括具有适于接收弓丝的弓丝槽的支架主体。 可移动部件与支架主体接合并且能够在打开位置和关闭位置之间移动。 托架主体和可移动部件可以由透明或半透明的多晶陶瓷制成,以改善美观。 多晶陶瓷具有特征在于大于3.4μm至约6μm的平均晶粒尺寸的晶粒尺寸分布。 多晶陶瓷的断裂韧性可以至少为4.0MPa·m1 / 2。 晶粒尺寸分布可能不被表征为对数正态分布,并且可以是多峰分布。 多晶陶瓷可以包括氧化铝或氧化铝。 粒度分布的特征在于具有至多约50%的晶粒尺寸小于约3μm。 晶粒尺寸分布的特征在于具有至多约90%的晶粒尺寸小于约10μm。

A movable member is engaged with the bracket body and is movable between an opened position and a closed position. The bracket body and movable member are made from a transparent or translucent ceramic for improved aesthetics. The bracket body may include one or more stop surfaces that limit movement of the moveable member in the gingival direction. The bracket body may include a support surface that is positioned lingually of a labial edge of the archwire slot. The moveable member may include a bracket-engaging portion having a first surface confronting the bracket body and a slot-covering portion having a second surface confronting the archwire slot, the first and second surfaces being offset from one another.

    • An implantable lead includes a lead body, having a distal end and a proximal end, configured to be implanted in a patient, and a connector provided at the proximal end. A load detection assembly is provided on the lead body, wherein the load detection assembly includes a housing that holds a sensor and a load transfer element. The load transfer element engages the sensor and conveys a force induced on the load transfer element to the sensor. Optionally, the housing may isolate the sensor from lateral forces and the load transfer element may only convey, to the sensor, longitudinal forces that are directed in a predetermined single direction. For example, the load transfer element may only convey, to the sensor, longitudinal forces that are directed perpendicular to a surface of the sensor.
    • 可植入引线包括具有远端和近端的引线体,构造成植入患者体内,以及设置在近端的连接器。 负载检测组件设置在引线主体上,其中负载检测组件包括保持传感器和负载传递元件的壳体。 负载传递元件与传感器接合并将在负载传递元件上感应的力传递到传感器。 可选地,壳体可以将传感器与侧向力隔离,并且负载传递元件可以仅向传感器传送以预定的单个方向指向的纵向力。 例如,载荷传递元件可以仅向传感器输送垂直于传感器表面的纵向力。
