Abstract

An elongate supporting part in a replacement construction and a method of production thereof, the replacement construction is intended to be secured in the human body in implants with unique longitudinal courses by using at least one working model in which the longitudinal courses and connection surfaces of the implants are represented by representation members. The method comprising the steps of generating an electrical representation of the outer shape of the working model and providing this information to computer equipment. The computer equipment performs calculations in order to establish an outer shape for the supporting part and generates machining information based on this outer shape which represents the shape of the supporting part. This information is provided to a machining device which machines a blank and an electro erosion tool is created by providing electrodes in a working model at positions of the representation members. The electrodes are arranged in the same longitudinal direction as the representation members. The electro erosion tool is used to create a recess in the blank for contact members whereby the blank can be anchored on the implants. The recess and the contact members have a longitudinal axis which coincide with the axis of the implants.
