    • The invention relates to a dental implant comprising an implant body provided with a central receiving opening, a structural element provided with a journal engaging in the receiving opening, and a tension bolt which penetrates a borehole of the structural element and is screwed into an inner thread located in the receiving opening. First and second indexing elements are arranged in an apical region of the structural element, in order to pre-define the rotational position of the structural element in relation to the implant body. The at least one first indexing element is associated with the implant body or the structural element in a rotationally fixed manner, and at least two second indexing elements are associated with the structural element or the implant body in a rotationally fixed manner. The indexing elements extend especially at least partially into the region of the conical outer surface of the journal.
    • 本发明涉及一种牙科植入物,其包括植入物主体,该植入体设置有中央容纳开口,设置有接合在接收开口中的轴颈的结构元件和穿过结构元件的钻孔并被拧入内螺纹的张紧螺栓 位于接收口。 第一和第二分度元件布置在结构元件的顶部区域中,以便预先限定结构元件相对于植入体的旋转位置。 至少一个第一分度元件以旋转固定的方式与植入体或结构元件相关联,并且至少两个第二分度元件以旋转固定的方式与结构元件或植入体相关联。 分度元件特别地至少部分延伸到轴颈的锥形外表面的区域中。

    • A dental implant is provided that can be firmly fixed in an oral cavity, even if the amount of bone required to embed the implant is small. A necessary amount of bone can be secured by generating new bone so that the fixture part of the implant can be fixed in the bone. The fixture part of the implant includes several members movably connected to each other so that the fixture part is adjustable in length. The fixture part includes a first member made up of an uppermost member, a middle member, and an end member. It is preferred that the middle member be cylindrical or rod-shaped with male screws extending radially outwardly from an outer circumferential periphery thereof. The fixture part also includes a second member which is a hollow cylinder. It is preferred that the hollow cylinder have a tapped hole on one end with female screw on an inner periphery thereof so that the middle member of the first member can be screwed into the second member. The continuous stimulating force formed by the embedment of the implant into bone and the lifting up of the mucous membrane by extending the fixture part of the implant, contributes to the osteogenesis around the implant.
