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.

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.

It is disclosed a dental implant (130; 230; 330) for promoting bone growth. The dental implant comprises an elongated implant body having a coronal end portion (131; 231; 331) and an apical end portion (132; 232; 332), at least one external thread (140; 240; 340) and a flute arrangement having a depth. The flute arrangement has at least two helical flutes (150; 250; 350) that spiral in the general direction of said at least one external thread (140; 240; 340). The flutes (150; 250; 350) propagate with a greater lead than said at least one thread (140; 240; 340). The flute arrangement is capable of scraping off and transferring bone debris in the coronal direction of the implant during insertion. It is also disclosed a method of using the dental implant and an implant system according to the present invention.

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).
