Abstract:
1. A method for manufacturing a prosthesis for replacing at least one tooth, wherein the prosthesis is arranged for insertion in a patient's jawbone and the prosthesis comprises an implant and an abutment, wherein the abutment and the implant are arranged for placing the abutment on the implant; the method comprising the steps of: defining a shape of the prosthesis and a location in the jawbone for the prosthesis to be placed by using first image data of a first image taken by a CT scan (CT Scan I) of the patient's jawbone and by using second image data of a second image obtained from an optical scan of a gypsum cast, the gypsum cast taken from the patient's mouth, wherein the method comprises the step of correlating the first image data and the second image data by: extracting from the first image data first reference marker data relating to a position of a first reference marker in the first image; extracting from the second image data second reference marker data relating to a position of a second reference marker in the second image, the second reference marker being the same as the first reference marker; retrieving from a second optical scan third image data of a third image taken from a registration bite for registration of a shape of an antagonist tooth, the tooth being antagonistic in relation to the location of the tooth to be replaced, merging the second reference marker data from the second image with the third image data,
