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 system for implantation of a spinal stabilization system includes a vertebral anchor having a top portion. The top portion has a perimeter and a first engaging element. The first engaging element has a first longitudinal axis that is generally parallel to a second longitudinal axis of the top portion. The perimeter extends around the second longitudinal axis. The system also includes a driving tool that has a second engaging element that is configured to cooperate with the first engaging element to substantially restrict rotation of the driving tool relative to the top portion about the second longitudinal axis. The first engaging element is configured to slidably receive the second engaging element in a direction along the first longitudinal axis, and the second engaging element is configured to extend substantially within the perimeter of the top portion.
