A drill bit and method for normalizing bone is provided. The drill bit has a non-round drill bit core that is adapted to cut hard bone and to not cut soft bone. The drill bit has a cutting edge which may be positioned within a compression zone of the non-round drill bit core. The rotational speed of the drill bit and the profile of the drill bit core are tuned so that hard bone recovers into a cutting zone defined by the cutting edge while soft bone remains outside of the cutting zone. The insertion torque of the drill bit can be measured to determine when the normalization is adequate.

Dentistry tool

A dental implant (), in particular for insertion into bone tissue of a patient, comprising: a core body () having an apical end (), a coronal end (), and an outer surface () extending along a longitudinal direction between said apical end () and said coronal end (); and at least one thread () located on at least a threaded portion of said outer surface (), should have superior properties regarding primary and secondary stability. According to the invention this is achieved in that the core body () comprises a core shaped zone (), preferably next to said coronal end (), in which core shaped zone () the cross-section of said core body () has a number of main directions in which the radius measuring the distance between the center () of the cross section and its outer contour takes a relative maximum value and thus a higher value than in neighboring orientations, a core circular zone (), preferably next to said apical end (), in which core circular zone () the cross-section of said core body () is basically circularly shaped, and, as seen in said longitudinal direction, a transition zone () positioned between said core shaped zone () and said core circular zone (), in which transition zone () the geometry of the cross-section of said core body (), as a function of a parameter characteristic for a coordinate in said longitudinal direction, changes continuously from a basically circular shape next to said core circular zone () to a shape in which the cross-section of said core body () corresponds to the shape of the cross section in said core shaped zone (). The invention further relates to an insertion tool () for inserting a dental implant () into bone tissue of a patient. Moreover, the invention relates to a combination of such a dental implant () and such an insertion tool ().

Dental implant, insertion tool for dental implant and combination of dental implant and insertion tool

The present invention relates to a connection assembly for attaching a dental component to a dental implant, a dental component for the connection assembly and a method to use the connection assembly. The connection assembly () is removably attachable to the dental implant (), preferably with the dental component () attached to the connection assembly, and a dental component is attachable to the connection assembly in a pre-fastened state or a fastened state. The pre-fastened state, when the connection assembly is attached to the dental implant, the connection assembly allows for adjustment of a relative position and/or orientation between the dental component and the dental implant. In the fastened state, the relative position and/or orientation between the dental component and the connection assembly is fixed, while the connection assembly is in particular detachable from the dental implant with the dental component attached to the connection assembly in the fastened state.
