Abstract

The implant is a screw-shaped dental implant with a diameter of 3.5 mm. The thread profile has two thread flanks and the height of the thread is D. The top radius is formed at the apex of the thread profile at the intersection of the two thread flanks is designated R, and the bottom radius between two adjacent thread profiles. The thread flanks form an angle v with a plane which is perpendicular to a cross-section of the thread and perpendicular to the surface of the implant body. The distance L is defined as the distance between the points of intersection between the two flanks on a thread and the surface of the implant body.. The surface of the implant body is defined as the cylindrical surface touching the deepest parts of the threads. A standard prior art screw-shaped implant with an overall diameter of 3.5 mm would typically be provided with threads having a height D of about 0.35 mm, a flank angle v of 300, a top radius R of about 0.65 mm corresponding to about 0.2xD and bottom radius of about 0.5 mm corresponding to about 0.15xD.
