The present invention relates to a dental implant, and more particularly, to a dental implant including a fixture 10, an abutment 30 coupled to an upper end of the fixture 10, and an abutment fixing screw 40 coupling the abutment 30 to the fixture 10. The fixture 10 is molded of ceramic and includes a screw part 13 disposed on an outer circumferential surface and a screw hole 14, to which the abutment fixing screw 40 is coupled, disposed in a central axis direction. A helical coil 20 is disposed between the screw hole 14 of the fixture 10 and the abutment fixing screw 40 to couple an outer portion 21a of the helical coil 20 to a screw valley 14a of the screw hole 14 of the ceramic fixture 10 and an inner portion 21b to a valley 41a of the screw part 41 of the abutment fixing screw 40 in a screw coupling manner.

A dental prosthesis formed of a composition comprising a polymeric material, the prosthesis comprising one or more locating formations adapted to receive a dental implant fixture or dental abutment, the or each locating formation comprising a recess comprising a first recess portion formed in the polymeric material of the prosthesis, and a second recess portion provided in a sleeve located in the prosthesis.

An arrangement with a tool and with a fastening means having a longitudinal direction is provided. The tool is designed to screw the fastening means into a body in the longitudinal direction; the tool has a blade with a first holding element and a second holding element; the fastening means has a first holding section with a complementary first holding element and a second holding section with a complementary second holding element. In the first holding section, the first holding element and the complementary first holding element interact in such a way that a translatory movement of the blade in the longitudinal direction is blocked. In the second holding section, the second holding element and the complementary second holding element interact in such a way that a rotary movement of the blade can be transferred to the fastening means and the fastening means can be screwed into the body.

The invention relates to an adapter (1, 1′) for attaching a dental superstructure (50) to a dental implant (30). The adapter (1, 1′) comprises a coronal attachment portion (2, 2′) for attaching the adapter (1, 1′) to the dental superstructure (50), an apical attachment portion (4) for attaching the adapter (1, 1′) to the dental implant (30) and an intermediate portion (6) arranged between the coronal attachment portion (2, 2′) and the apical attachment portion (4). The apical attachment portion (4) is a protrusion defining an apical end portion of the adapter (1, 1′) and configured to be received in a corresponding recess (32) of the dental implant (30). The protrusion is rotationally symmetric, so that the adapter (1, 1′) is rotatable relative to the dental implant (30) in the state of attachment of the adapter (1, 1′) to the dental implant (30). Further, the invention relates to a dental assembly comprising the dental superstructure (50) and at least one such adapter (1, 1′).

A dental implant includes an insert element of a titanium-based material inserted and soldered into a blind hole in an anchoring element of a ceramic. The insert element has spacer members to center it in the blind hole, with a uniform circumferential gap space relative to the anchoring element. A portion of the insert element protrudes outwardly beyond an end face of the anchoring element. The blind hole is partly filled with a glass solder, and the insert element is inserted into the blind hole, whereby some of the glass solder is displaced out of the gap space onto the end face of the anchoring element and the protruding portion of the insert element. A thermal soldering process secures the insert element into the anchoring element. The protruding portion of the insert element and remaining excess solder are removed to form a planar surface.

A single tooth implant for a fixed dental prosthesis includes a substantially cylindrical main part which can be inserted into a bore in a jaw bone; an abutment which can be inserted into an annular recess in the main part, the abutment having a bore for receiving a retaining screw and a securing head for the dental prosthesis; and a retaining screw which can be inserted into the blind hole of the main part and traverses the abutment; and at least one annular gap between the abutment and the main part, in which gap a damping element is arranged.

A dental implant system with a ceramic implant and with an abutment, which moreover includes an insert element for the ceramic implant. The insert element is either manufactured from non-ceramic material or is manufactured essentially of injection molded ceramic. The insert element matches with a recess a proximal region of the ceramic implant and is inserted or insertable into the recess. The insert element serves for the fastening of the abutment and for this is equipped with fastening structures. The insert element, which is arranged in the recess of the ceramic implant, is connectable or connected to the ceramic implant by way of a frictional connection and/or positive connection with respect to axial traction.

A dental implant includes an insertion portion which extends along an implant axis, and a coronal projection for receiving an abutment having a dental prosthesis formed thereon, which can be mounted on the dental implant with a screw. The insertion portion includes a coronal region and an apical region. The coronal projection extends from the coronal region of the insertion portion in the coronal direction and along a prosthesis axis. The coronal projection and the insertion portion are integrally connected in one piece. The prosthesis axis and the implant axis are inclined towards each other, and the abutment having the dental prosthesis formed thereon is attachable to the dental implant with only one screwing operation in the direction of the prosthesis axis.

The present invention is related to the dentistry field. More precisely, the present invention relates to a system for insertion into the root canal for obtaining a root fastening element to support crowns comprising a sleeve of flexible and moldable material, non-adherent to the walls of the root canal, wherein the sleeve comprises a root section and a crown section which are filled with fibers in different arrangements. In addition, the present invention is related to a method for obtaining a fastening element using the system and root fastening element to support crowns.

Dental component (1) for the individual prosthetic reconstruction of a tooth, intended to be received on a dental implant, comprising: a first element (3) with an angled through-passage (4), a second element (7) intended to be received against or in a dental implant (2),

Means of assembly (9, 13a-13c) between the first (3) and second (7) elements make it possible effectively to limit the removal of material to be performed in the first element (3) in order to create the angled through-passage (4).
