Abstract: The invention relates to an apparatus for releasable attachment of a removable dental prosthesis to a head part of an implant or of an abutment that can be anchored in an implant, comprising a retention matrix (1) having a receptacle that accommodates a circular-ring-shaped retention element (2) that has at least two clamping arms (22), which is disposed so as to be displaceable along a center axis of the retention matrix (1), wherein the at least two clamping arms (22) form a mantle surface that widens conically toward the outside, and that the receptacle for the retainer element (2) has two sections (14, 15) having a different inside diameter, against the transition of which the at least two clamping arms (22) lie. The invention furthermore relates to a dental implant system, having such an apparatus.

Abstract: The invention relates to medical element and a method for securing the medical element in an implant, where the medical element has a connecting pin which is received in a receiving recess of the implant, the pin having a projection on at least one wing of a clip element and movable transversally relative to the longitudinal extension and brought into engagement with a radially outwardly facing corresponding depression in a jacket surface of the receiving recess such that the wing is subsequently secured against radial movement by hardening of a curable compound in the receiving recess.

Abstract: A method is disclosed for receiving a medical element in a manipulation apparatus in such a way that it can be inserted in an implant or be removed therefrom and the medical element is secured against longitudinal displacement by means of clip element, whereby a security element is introduced into the clip element such that the clip element is spread or blocked perpendicular to the longitudinal axis.

Abstract: Stable packaging for a dental implant, having a rigid enclosure and an implant holder situated therein, which enclosure is able to stand on two different planes, has a receptacle for the implant holder, an opening for access to the implant holder, and/or an implant held in the implant holder, and which implant holder has a recess for accommodating the implant.

Abstract: The screw element is composed of a threaded sleeve (1), a locknut (2) and a cone screw (3). The threaded sleeve (1) has an edge (12) and following the edge (12) a portion (14) that is free of threads; the cone screw (3) has a head (35), a threaded shaft (36) and, between head (35) and threaded shaft (36), a portion (33) that is free of threads; the locknut (2) has an internal cone (22) whose portion having the smallest diameter is provided with an internal thread (23) that is adapted to the threaded shaft (36) of the cone screw (3). The threaded sleeve (36) of the cone screw (3) is screwed into the threaded shaft (1) and its head (35) is supported in the internal cone (22).
