Provided is a technique of allowing a dental implant to be stably placed after extraction, to be accurately placed in a tooth extraction socket, and to be stably placed in the tooth extraction socket according to implantation position and angle. A method of manufacturing a scaffold for treatment of a tooth extraction socket and implantation of a dental implant includes receiving dental implantation information of dental CT data which is previously input via a terminal of a manager; manufacturing, by using a three-dimensional (3D) printer, a 3D model comprising alveolar bones and teeth, which are distinguished therebetween, based on a medical image file that is a medical image file (DICOM file) of the dental CT data; performing virtual tooth-extraction by removing, from the manufactured 3D model, a region corresponding to a tooth in a tooth-extraction target area; and manufacturing, by using the 3D printer, a scaffold to be placed in an actual tooth extraction socket according to a shape of a tooth extraction socket that exists in the manufactured 3D model as a result of the virtual tooth-extraction, wherein, when the scaffold is manufactured, image data of the scaffold is amended to allow a guide hole for implanting the dental implant to be formed in the scaffold based on the dental implantation information.
