Nobel Biocare is a company that manufactures dental implants and CAD/CAM-based individualized prosthetics and is headquartered in Kloten, Switzerland near the Zürich Airport. Nobel Biocare in its current form was founded in 2002. It originates in a partnership formed in 1978 between Swedish medical researcher Professor Per-Ingvar Brånemark and Bofors, a Swedish company, to industrialize Brånemark’s discovery of osseointegration Nobel Biocare is listed at the SIX Swiss Exchange.

A surface structure is produced on an outer surface of an implant or a fixture and forms a base structure in a range of implants related to different types and qualities of jaw bone. During production of the surface, parts of a turning tool are placed against the implant or against a blank which is intended to form the implant. The parts and/or the implant are assigned controls which give rise to mutual displacements between the parts and the implant so that the parts follow a substantially spiral trajectory along the outer surface. By means of said controls, a long wave pattern is formed with successive peaks and with through lying between these. In this connection, a through can be arranged adjacent to the outer parts of an existing thread. The controls are chosen so as to produce through depths in the range of 25 to 250 m, preferably 50 to 200 m. The invention also relates to an implant which bas the same character as the implant produced by the method.

The invention relates to a retention element (1) for attaching a first dental component (20), such as an abutment, to a second dental component (30), such as a dental implant. The retention element (1) comprises a coronal attachment portion (2) for attaching the retention element (1) to the first dental component (20), and an apical attachment portion (4) for attaching the retention element (1) to the second dental component (30). The retention element (1) is elastically deformable at least in all directions perpendicular to the direction from the apical attachment portion (4) towards the coronal attachment portion (2). The apical attachment portion (4) comprises at least one projection (8) extending in one or more directions substantially perpendicular to the direction from the apical attachment portion (4) towards the coronal attachment portion (2). Further, the invention relates to a dental assembly comprising the retention element (1) and to a use of the retention element (1) for attaching a first dental component (20), such as an abutment, to a second dental component (30), such as a dental implant, outside a human or animal body.

The present application relates to a fitting for insertion into a dental implant in an insertion orientation defining a central insertion axis and an insertion direction of the fitting. The fitting includes at least one resilient spring member being expandable perpendicularly to the insertion axis of the fitting for impeding a movement of the fitting relative to the dental implant along the insertion axis when inserted into the dental implant. It further includes an alignment feature for rotationally aligning the fitting relative to the dental implant about the insertion axis. The fitting is characterized in that the alignment feature extends further in the insertion direction than the spring member.

The present invention relates to a placement device for a dental component, a method for handling a dental component with a placement device, a dental component for placement with a placement device and a set comprising a placement device and a dental component. The placement device (1) for a dental component (2) is preferably an implant and comprises a proximal end (11), a distal end (12) and a coupling mechanism (20) for coupling the distal end (12) to the dental component. The coupling mechanism includes at least one movable pin (21) having a longitudinal axis (A1) and being movable along its longitudinal axis (A1) relative to the placement device (1) for engaging the dental component. It also includes at least one engagement part (28) at the distal end of the placement device (1) for engaging the dental component, the engagement part having a longitudinal axis (A2). A secure interlock between the dental component and the placement device is achieved by arranging the longitudinal axis (A2) of the engagement part (28) at an angle () relative to the longitudinal axis (A1) of the movable pin (21).

A dental implant that facilitates insertion includes a body having a coronal end and an apical end opposite the coronal end. An implant-prosthetic interface region is provided adjacent the coronal end. A tapered region is adjacent the apical end. A variable profile helical thread extends along the tapered region. The thread becomes broader in the apical-coronal direction and higher in the coronal-apical direction. The threads include an apical side, a coronal side and a lateral edge connecting them. The variable profile thread includes an expanding length of the lateral edge while the distance of the lateral edge from the base is reduced in the direction of the coronal end. The implant also has a gradual compressing tapered core, a self drilling apical end with a spiral tap, and a coronal end with and inverse tapering.
