Highly self-tapping dental implant system with hybrid cone type connection and interlocking rails, which allows high insertion (or removal) torque and double parallel cone locking between the implant, prosthetic abutment and internal screw, even in its 3.0 mm diameter embodiment, and gives the whole system high primary and secondary stability, optimal watertightness thanks to the double cone sealing, as well as predictable long-term fixation of the dental prosthesis on the implant.

A guide-sleeve is couplable to an oral surgical guide at a fixed rotational orientation, height, and angle with respect to oral anatomy. An implant delivery device, couplable to a dental implant, drives the implant into tissue of the subject by rotation of the delivery device about its longitudinal axis until the delivery device lockingly engages the guide-sleeve. When the implant lockingly engages the guide-sleeve, the implant is disposed in the tissue at a fixed rotational orientation, depth, and angle with respect to the oral anatomy, and any further advancement and rotation of the dental implant with respect to the tissue is prevented. Other embodiments are also described.

The present invention relates to a dental abutment blank comprising a body having a first end and a second end, a connection section at the first end that is configured to be connected to a dental implant, a channel having a longitudinal axis and defining an opening at the first end and a closed end at a distance from the second end of the body; to methods for manufacturing a dental prosthesis having an angulated screw channel from said blank as well as to a dental prosthesis having an angulated screw channel manufactured from said blank.

The invention relates to a dental component, such as an abutment, an abutment replica, an abutment blank, a customized abutment, a scan abutment, a digital transfer coping, an impression pick-up element, a healing cap or a driver, comprises a first indexing element and at least two second indexing elements having apical ends located apically of the apical end of said first indexing element. The invention also relates to a dental implant which comprises a dental component having first and second indexing elements and a fixture having third and fourth indexing elements, wherein the first and third indexing elements can only engage with each other after the second and fourth indexing elements have engaged with each other. The invention also relates to a fixture.

A screw-shaped anchoring fixture for anchoring a prosthesis in the skull bone. The anchoring fixture comprises a main body configured to be implanted into the bone and a flange configured to function as a stop to prevent the main body from completely penetrating through the bone. The main body comprises a distal tapered apical portion, a first portion, and a second portion. The inner diameter of the second portion is greater than the inner diameter of the first portion. The method for inserting the anchoring fixture includes providing the anchoring fixture, drilling a hole, and inserting the anchoring fixture into the hole until the flange contacts the skull bone, wherein the hole has a diameter that is greater than the inner diameter of the first portion and less than the outer diameter of the second portion.

Disclosed is a tooth replacement forming device (10) comprising an abutment on or to which a dental structure made of dental material, especially ceramics, can be fastened. The abutment is mounted on the implant using a detachable connection, in particular a screw connection, the abutment being provided with an implant connection, a collar, and a tubular portion to be connected to the dental structure. The disclosed device (10) is characterized in that a surrounding auxiliary element made of a residue-free material is arranged in such a way as to rest against the tubular portion.

The present invention addresses above-noted objectives by providing a dental component that includes a coronal end, an apical end, and a longitudinal axis extending between the coronal end and the apical end. The dental component also includes an interface for assembly to another dental component, the interface comprising at least one indexing section for rotationally locking the dental component to the other dental component and at least one guiding section. The at least one guiding section and the at least one indexing section alternate about the longitudinal axis, wherein the guiding section includes an apically facing or coronally facing guiding surface. Further, a tangent to at least a portion of the guiding surface has a slope towards the next indexing section about the longitudinal axis.

A dental implant assembly comprising a healing component (10) removably attachable to a coronal end of a dental implant (40) and an impression component (20) having an outer surface, an upper portion (21) and a lower portion (22) and being removably attachable to the healing component (10). The healing component (10) has an internal bore (13) for receiving at least part of the lower portion (22) of said impression component (20) therein and the internal bore having a shoulder on an inner surface thereof acting as an axial locator providing an endstop for axial movement of said impression component (20) within said bore (13). The assembly further comprises a rotational locator limiting rotational movement between said impression component (20) and said healing component (10), the rotational locator comprising a formation on said outer surface of the impression component (20) and/or a formation on said inner surface of said bore (13) of the healing component (10). Using this assembly, a digital impression recording positional information about the dental implant can be taken without having to remove the healing component (10) from the implant (40).

A dental implant structure includes a fixture fixed to an alveolar bone, an abutment coupled to the fixture and configured to attach an artificial tooth thereto, and a coupling element configured to couple the fixture and the abutment to each other. In the dental implant structure, the fixture includes a lower fixture portion fixed to the alveolar bone and an upper fixture portion coupled to the abutment, a first thread is formed on a part or all of a surface of the lower fixture portion so as to be fixed to the alveolar bone, the lower fixture portion has a shape extending along a rotation axis of the first thread, a second thread is formed on a part or all of a surface of the upper fixture portion, and the upper fixture portion has a shape extending along a rotation axis of the second thread.
