Abstract
The present invention provides a design method designing an implant specific drill bit comprising steps; e. determining or selecting a size and shape of an orthopedic implant comprising a circular shaped implant body and a centrally placed circular shaped extending post protruding from the bone contacting surface in a longitudinal y-axis direction of the implant; and f. selecting design parameters for the implant specific drill bit by; —selecting the width of the broadest part of the bone remover in a side view to correspond to, or to be slightly smaller than, the diameter of the implant body of the specific implant that is to be implanted; —selecting the rotational volume and the length of the central drill part to correspond to, or to be slightly smaller than, the diameter of the extending post of the specific implant that is to be implanted; —selecting the curvature of the cutting edge that is placed anywhere peripherally around or surrounding the central drill part of the implant specific drill bit to correspond to the curvature of the bone contacting surface of the implant.
