    • A dental instrument adapted to be used as a file or reamer for removing dead or damaged tissue from the root canal of a tooth. The instrument comprises a body part, of which solely the proximal part is shown, an intermediate part and a shank, these three parts preferably being integral with each other. The shank is adapted to be inserted releasably in a chuck, so that it may be driven to rotation when the instrument is used for treating the root canal of a tooth (not shown). A fracture groove between the intermediate part and the shank ensures that fracture occurs at this location, if the body part gets stuck in a tooth, thus avoiding the risk of small distal parts of the instrument being left in the root canal in a manner making it impossible to remove them.
    • 适合用作文件或扩孔器的牙科器械,用于从牙根的根管去除死亡或损伤的组织。 仪器包括仅示出近端部分的主体部分,中间部分和柄部,这三个部分优选地彼此成一体。 柄部适于被可释放地插入卡盘中,使得当仪器用于治疗牙齿的根管(未示出)时,该柄可被驱动旋转。 中间部分和柄之间的断裂槽确保在该位置处发生骨折,如果身体部分卡在牙齿中,从而避免器械的小远端部分留在根管中的风险,使其成为 不可能删除它们。

    • A light emitting apparatus for curing a photocurable dental prosthesis in a patient's tooth that comprises a LED carrying part connected to a handle. The LED carrying part comprises a first plurality of LEDs directed to a first side of the tooth, and a second plurality of LEDs directed to a second side of the tooth. The present invention also relates to a method of curing a photocurable dental prosthesis in a patient's tooth, in which a light emitting apparatus is provided that comprises LEDs that are mounted on a substrate, the substrate being covered with a clear coating embedding the LEDs, and the LEDs being placed so proximate to the photocurable dental prostheses that the smallest distance between the outer surface of the clear coating and the outer surface of the photocurable dental prostheses is less than 2 mm. The LED carrying part can be connected to a handle for grasping by a user's hand, or be provided with a structure for engaging an opposite tooth so that it can be held in place between the patient's teeth.
    • 一种用于固化患者牙齿中的可光固化牙科假体的发光设备,其包括连接到手柄的LED承载部件。 LED携带部分包括指向齿的第一侧的第一多个LED以及指向牙的第二侧的第二多个LED。 本发明还涉及一种固化患者牙齿中的可光固化的假牙的方法,其中提供了一种发光装置,其包括安装在基底上的LED,所述基底被嵌入LED的透明涂层覆盖,以及 LED被放置得如此靠近可光固化的牙科假体,即透明涂层的外表面和可光固化的假牙的外表面之间的最小距离小于2mm。 LED携带部件可以连接到用于由用户抓握的手柄,或者设置有用于接合相对的齿的结构,使得其可以保持在患者的牙齿之间的适当位置。

    • An endodontic obturator for filling an endodontically prepared root canal of a tooth. The endodontic obturator includes an elongated shaft of having a proximate portion and a distal portion. The proximate portion has a handle portion connected thereto or is suitable for being releasably connected to a handle portion. A layer of filler material is coated about the shaft. The filler material has a low operating temperature at which it becomes plasticized or partially molten. The filler material in the layer disposed close to the distal end can have a higher viscosity at the operating temperate than the filler material close to the distal end.
    • 用于填充牙根牙根管根管的根管闭塞器。 牙根管闭塞器包括具有近端部分和远端部分的细长轴。 近端部分具有连接到其上的手柄部分或适于可释放地连接到手柄部分。 围绕轴涂覆一层填充材料。 填充材料具有低的工作温度,在该温度下它变得塑化或部分熔融。 靠近远端设置的层中的填充材料在操作温度下可以具有比靠近远端的填充材料更高的粘度。
