Method of customizing and manufacturing tooling for preparing an osteotomy for receiving a dental implant, in particular drills and/or osteotomes. The method comprises the steps of: —receiving scan data modeling a planned position of the osteotomy and surrounding jaw bone area； —generating on the basis of the scan data a virtual implant model of the dental implant； —generating a virtual tooling model of the tooling on basis of the virtual implant model； —computer aided manufacturing of the tooling on the basis of the virtual tooling model.
