An implant system including a dental implant and an abutment produced from a ceramic material, wherein the abutment includes a first anti-rotation element with multiple grooves and the dental implant includes a second anti-rotation element, which is complementary thereto, with multiple ribs, wherein the grooves are open toward a proximal end of the abutment.

A dental prosthesis arrangement includes a lower part assigned to a jaw implant and an upper part assigned to a superstructure. The lower part engages in the upper part along a central axis. The lower part is supported against the upper part at several contact faces. The lower part and the upper part are connected releasably to each other via a securing device which provides a retaining force against axial withdrawal of the upper part from the lower part. A first radially inwardly directed structure is provided on the lower part and a second radially outwardly directed structure is provided on the upper part for receiving a holding element that provides the retaining force. A fastener passing through the upper part and connected to the lower part can alternatively fix the upper part to the lower part.

A dental treatment method is provided. In this method, a tooth of a patient is extracted and prepared to provide a root part. A root canal in the extracted tooth is prepared and treated. A post of an abutment is fitted into the root canal to attach the root part to the abutment. The abutment having the root part is attached to a dental implant. With the root part attached to the abutment, periodontal connective tissue maintains the jaw bone associated with the extracted tooth, without significant hard tissue loss.

A dental prosthesis with a threaded crown on a post and core includes a dental implant, a post and core having a portion adapted to be inserted into the implant and another portion protruding from the implant, a screw and a crown, the implant being adapted to be fixed to a bone and the post and core being adapted to be fixed to the implant with a thread, the crown being fixed to the post and core with the screw, wherein the post and core provides a connection element between the implant and the crown, a separation area being provided between the area where the post and core is housed in the crown and the area where the post and core is housed in the implant, and wherein the portion of the post and core protruding from the implant does not feature a diameter increase.

Dental implant, comprising an external thread arranged on an outside of the dental implant for fastening the dental implant to a jawbone. Further, the implant comprises an opening extending along a longitudinal axis of the dental implant, in which opening an internal thread for fastening a superstructure to the dental implant is arranged. Still further, the implant comprises an interface for fastening the superstructure to the dental implant, which interface is arranged at a front end of the dental implant. The interface is suitable for direct attachment of a superstructure to the dental implant without the use of an abutment.

A dental implant having a substantially cylindrical shape with a longitudinal axis defining a longitudinal direction, including: a coronal section including a coronal end of the implant; a threaded region extending apically from the coronal section to an apical tip of the implant; and an internal blind bore for connection to a secondary part, including: a stabilizing section extending apically from the coronal end; and a drive and indexing section which extends apically from an apical end of the stabilizing section, which includes a plurality of connecting lobes having a concave shape and extending in the longitudinal direction, being interconnected by respective lobe linking areas, including: two convex sections extending in the longitudinal direction and adjacent to a respective connecting lobe; and a concave section extending in the longitudinal direction between the two convex sections. Further, a secondary part and an insertion tool of a configuration matching the dental implant.

Dental implants, dental abutments, and dental systems are disclosed. A dental implant can include an implant body having a longitudinal axis, a coronal end, and an apical end. An internal bore can be provided within the implant body, and can have a coronal end, adjacent to the coronal end of the implant body, and an apical end. The internal bore can include a first internally facing surface, extending from the coronal end of the internal bore towards the apical end of the internal bore, at least a portion of which tapers inwardly towards the apical end of the internal bore. The internal bore can further include an internally threaded portion positioned between an apical end of the first internally facing surface and the apical end of the internal bore. A dental abutment can be configured to engage with the dental implant.

The invention relates to an adaptor system for a dental prosthesis. The adaptor system comprises an abutment and an adaptor, wherein said adaptor is adapted to connect to a prior art or new implants and is also connected to the abutment by a rotational connection. The adaptor and the abutment are secured to the implant by a screw that retains the angular position of the abutment.

An implant fixture is disclosed. The implant fixture contains an elongated shaft section, and a head section, wherein the head section contains at least one concave area for bone growth therein.
