Abstract

The prosthesis is provided with a medial narrow side which extends on a hyperbola from a conical distal section to a boundary plane at which the blade is connected to the neck of the prosthesis. The vertex of the hyperbola is disposed at the point of intersection of the curved medial narrow side with the neck and a tangent to the hyperbola at the point of intersection with the distal section is one-half the conical angle of the blade.
