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 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.


In an arrangement for obtaining reliable anchoring of a threaded implant in dentine, a hole is made in the bone substance. In the side wall of the hole it is possible to establish an internal threading which can cooperate with an external threading on the implant. The implant threading is arranged to force the bone substance out in essentially radial directions as a function of the extent to which the implant is screwed into the hole. The threading is arranged to effect greater forcing out of the bone substance at the outer parts of the hole than at the inner parts of the hole. The degree of forcing out is adapted in relation to the softness of the bone in order to achieve the reliable anchoring. Along at least part of the longitudinal direction of the implant, the implant threading can be given a non-circular configuration for the purpose of obtaining improved rotational stability in soft/weak bone.

A dental implant for supporting a dental prosthesis comprises a body portion and a top surface. The implant further comprises an internal cavity with an opening located at the top surface. The internal cavity comprises an interlock chamber having a depth measured from the top surface equal to a first distance. The interlock chamber comprising a cylindrical portion and plurality of semi-circular channels arranged around a periphery of the cylindrical portion. A threaded chamber that includes threads is located below the post-receiving chamber. The cylindrical portion has a first radius and the channels have a second radius, a ratio of the first radius to the second radius being between approximately 4:1. and 2:1.
