• 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,
• performing with use of the first and second reference marker data a geometric transformation operation on the second and third image data and/or the first image data to have a coincidence of the second and third image with the first image and to combine the first image data and the second and third image data into composite scan image data, and
• defining a shape for the drill guide from the first and second and third image data;
• the drill guide comprising a guiding hole and a drill tube, the drill tube being located in the guiding hole and arranged for holding, during use, a drill bit;
• the drill tube having an orientation for providing a drilling direction to coincide with an orientation for the implant and having a pre-calculated height for providing a depth transfer for a depth of the implant in the jawbone.
