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 describes a dental kit-of-parts including an implant abutment, a dental restoration and a screw. The head of the screw is provided in a recess formed in the kit-of-parts, with the screw shaft extending through a hole in the implant abutment. A channel in the dental restoration allows access to the screw head by a tool, wherein the diameter of the channel is smaller than the diameter of the screw head. The dental kit-of parts can be manufactured using rapid prototyping such that the captive screw is formed within the combination of the implant abutment and the dental restoration or through conventional means, with the dental abutment and the dental restoration being ex-situ connected to enclose the screw.
