Patent ID: 6846180

Claim:
A dental implant comprising: a) a bottommost implant tip located at an apex; b) a root part which has a length, extends to the implant tip, is intended to be fitted in a jawbone, and has a parabolic outer contour which, when placed in a cartesian system of x-y coordinates, with the implant tip positioned at the origin, follows the equation l y =K·4r x 2 , where l y represents a y coordinate value and r x represents an x coordinate value, and the constant K results from the equation K=l max /4r max 2 ; c) an implant neck adjoining the root part, which extends in a coronal direction and is intended to lie inside the gingiva; and d) an outer thread having a pitch and provided on the root part, wherein the root part has the parabolic outer contour along all of the length of the root part and as far as a theoretical ridge line at which the root part adjoins the implant neck, the root part at the ridge line having a maximum radius extending in a radial direction.
