摘要： 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.

摘要： An endosseous dental implant system includes a dental implant having a multi-sided projection at its top end and an internally threaded or unthreaded passage extending into the body of the implant through an opening in the projection at the top of the implant, and an abutment having an internal passage for receiving a fastener that passes through the internal passage of the abutment, and threads into the internal passage inside the implant. The abutment has a multi-sided internal cavity at its bottom end with each of the cavity sides perpendicular to the longitudinal axis of the abutment so that the cavity, when seated over the projection at the top of the implant, forms an anti-rotational, interlocking junction with the implant.

摘要： An implant for dental prostheses includes an endosseous portion and a stump. The endosseous portion includes a crown margin configured to be opposed to a corresponding crown margin of the stump. At least one of the crown margins is conical or however has a different taper with respect to the opposed crown margin so that, once the stump has been coupled to the endosseous portion, the contact and interference surface between the crown margins is a reduced annular surface.

摘要： A method of fixing a dental implant assembly is described. The assembly includes an implant, a driver/abutment device, and a spacer. The bottom portion of the device has a protrusion with an inferior aspect and a superior aspect. The spacer prevents the oversized, superior aspect of the device from engaging an interior cavity of the implant so that the driver is easily removable after insertion of the implant in the jaw of a patient. Removing the spacer permits the superior aspect to engage the interior cavity, thereby permanently fixing the driver to the implant.

摘要： A dental abutment system permitting to limit the steps and time required for a dental implant procedure. The dental abutment system (10) comprises a cap (12) coupled to a retentive member (14) that is coupled to a sheath (16). The cap (12) has a shaft (18) for coupling with a bore (24) of a dental implant (20) and the sheath (16) is coupled to the bore (24) of a dental prosthesis (26) such that the dental prosthesis (26) is frictionally retained to and removable from the cap (12). The retentive member (14) may include an area-of-weakness permitting it to break-away from the cap (12) to avoid the transmission of excessive forces to the implant (20).
