A highly precise implant implantation guide has been desired for safely and precisely performing a dental implant treatment. A method of producing an implant implantation guide according to the present invention includes the steps of: (1) preparing a guide block including an attachment portion and a processing portion; (2) acquiring CT image data of a patient with the guide block being worn by the patient; (3) determining an implant implantation position and an implant implantation direction through diagnosis based on the CT image data, and transforming information of the implantation position and the implantation direction thus determined into coordinate information based on a processing reference coordinate system; and (4) cutting the guide block through CAD/CAM so as to reflect the coordinate information obtained by the transformation.
