Abstract

A set of dental implants comprising two implants each having an anchoring head for a structural element and having an end face of a predetermined face diameter and a screw element with a thread core and a self-cutting outer thread. The thread core and the outer thread have three segments following one another in succession from crestal to apical, namely a crestal segment adjoining the anchoring head with a constant outer crestal diameter of the outer thread and a thread core conically tapering in the apical direction to a predetermined intermediate diameter, a middle segment with an outer diameter of the thread core substantially equal to the intermediate diameter, and a tip segment with an outer thread of an outer diameter tapering in the apical direction and a conically tapering diameter of the thread core. The face diameters of the two implants are different.
