1. A method for producing an elongate supporting part for a replacement construction in a human body and intended to be secured in implants with unique longitudinal courses, and using at least one working model in which said longitudinal courses and connection surfaces of said implants are represented by representation members, said method comprising the steps of:

  • reading an outer shape of said working model with a surface reading member to generate an electrical representation of said outer shape;

    supplying computer equipment with said electrical representation;

    performing calculations in said computer equipment to establish a shape for said supporting part, whereby said supporting part is accommodated within said outer shape of said replacement construction;

    generating machining information with said computer means which represents said shape of said supporting part;

    providing said machining information to a machining device;

    machining a blank with said machining device such that said blank obtains said shape;

    creating an electro-erosion tool by providing electro-erosion electrodes in said working model at positions for said representation members and arranging said electrodes in the same longitudinal direction as said representation members; and

    creating a recess in said blank with said electro-erosion tool for contact members, whereby said blank can be anchored on said implants via connection surfaces on said contact members, said recess and said contact members have longitudinal axes which coincide with axes of said implants.
