Abstract: 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.

Abstract: The invention relates to an arrangement for insertion of an implant, in particular of a dental implant, which has an external thread and can be screwed into a bone by means of a tool, wherein the implant has a receiving opening with an at least partially conical inner face. A pin of an attachment part, which can be connected to the implant after the latter's insertion, can be fitted into the receiving opening. The arrangement is to be further developed such that the insertion of the implant can be performed in a simple and yet functionally reliable manner.

Abstract: A system for insertion of implants, in particular dental implants, comprises a splint, which is provided with a bore and which is designed for positioning the implant onto an area intended for the insertion, in particular a bone, and can be placed on the latter. The system also includes an insertion or screwing tool for the implant, and the splint has a guide surface. The system is to be further designed such that the precise insertion of the implant can be predefined with a high degree of reliability.

Abstract: An arrangement including an instrument for the insertion of a dental implant including a template placeable on a bone or surrounding tissue. The template, or a first sleeve arranged within the template, includes a through-recess, through which the instrument can be guided. The arrangement enables exact alignment and guidance of the instrument and easy handling. A second sleeve that is axially displaceable on the instrument is provided, and axially fixed in a base position through automatically releasable connecting elements with predetermined retaining force such that when the retaining force is exceeded, the connecting elements can be automatically released and the second sleeve can be axially displaced. The instrument, together with the axially fixed second sleeve, can be inserted in the continuous recess and is aligned in the template via the outer surface of the second sleeve, the surface being configured relative to the inner surface of the recess.

Abstract: The invention proposes an abutment set for a dental implant, comprising an abutment post (2) for fixing to a dental implant (1), which abutment post is anatomically pre-configured, and an abutment cap (7), which cap is anatomically pre-configured, and adapted for mounting onto said abutment post without further machining by the customer; wherein the abutment post is adapted for fixing to a dental implant and for receiving said abutment cap without further machining by the customer, and the abutment cap is adapted to receiving a veneering (12); and the abutment cap and the abutment post being pre-fabricated for providing appropriate dental prostheses for a multiplicity of different patients, and wherein the abutment cap has means (10) for defined rotational and lateral fixing in impression material applied by a dentist, as well as a method for manufacturing a dental prosthesis.

Abstract: The invention relates to an implant system containing at least one drill and one implant, particularly a dental implant, which can be screwed into a bore hole made in a bone by means of a drill. Preferably, the implant comprises a self-cutting screw with a thread core. The aim of the invention is to further develop an implant system which guarantees high primary stability for a wide variety of bone qualities and requires little technical complexity. According to the invention, the implant and the drill are co-ordinated in such a manner according to bone quality that a compressed zone arises when the implant is screwed into the implant in the bone. The size of the compressed zone is greater for low bone quality than for high bone quality.

Abstract: A dental implant (1) includes a top section (17) and at least one top surface (7, 28) that is provided with a micro-roughened surface, such as an average roughness (RA) of about 0.7-1.1 ?m, by etching. The top surface may include a porous surface of pore dimensions of less than about 10 ?m or a coating, such as a 0.5 ?m thickness of titanium nitride. The roughened surfaces promote healing in and tissue growth at the top, enhancing the sealing effect at the epithelium interface with the implant.

Abstract: An implant is disclosed comprising a fixture component (1) intended for insertion into a bone, and at least one further abutment component (3) for providing a base for a prosthetic superstructure, and a connecting element (9) for mechanically securing the abutment (3) to the fixture (1), wherein the fixture (1) comprises an external thread (16) or other protrusions for improving engagement between the fixture (1) and the bone, wherein the connecting element (9) detachably interconnects the fixture (1) and the abutment (3), and wherein at least the fixture (1) and the abutment (3) are made of non-metal material, and method of making the same.

Abstract: A transfer element for transferring the position of an implanted dental implant body to a master model including at least one element that can be fixed in an impression material for transferring the axial or rotational position of the implant to a dental impression. The invention aims at enhancing the transfer element to enable easy impression making and high precision during transfer of the vertical position of the implant in addition to ensuring anti-rotational blocking. The transfer element includes a core (2) that may be connected to the implant body, and a guide sleeve (4), and the core (2) and the guide sleeve (4) are provided with mutually engaging, corresponding positioning elements (22, 23; 24, 25).

Abstract: The invention relates to a gingiva former which can be connected to a dental implant and has a head portion (2) which is located in the region of the gingiva. The gingiva former should be developed such that the formation of the soft tissue be improved. Thus it is suggested that the head portion (2) have at least one opening (14) for gingival fastening devices and that the opening (14) lead into a central bore (6) of the head portion (2).

Abstract: An oral surgical instrument (osteotome) for creating openings in the jawbone for the implantation of implants, which comprises a holder, a shaft and a working tip that has a circular cross section. A set of surgical instruments is provided with at least one preformer having a conical working tip and at least one implant bed former having a working tip which is adapted to the outer contour of the implant. The diameter of the working tip of the preformer is somewhat smaller than the largest diameter of the working tip of the implant bed former. By forming the openings in the jawbone using such instruments, the implants may be inserted with a greater fitting strength.
