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.

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 ().

A dental sensor clamp has a clamp body with a connector on one end for connecting the sensor clamp to a bite plate. A clamp body opposite end has a fixed stop locatable adjacent an apical area of a tooth. A clamping slide is mounted within a thickness of the clamp body, and the clamping slide supports a member providing a resilient clamping force upon the member being moved against the sensor and the fixed stop. The dental sensor clamp reliably secures an imaging sensor adjacent the apical area of the tooth.
