Provided is a technique of accurately forming a shape of a scaffold demanding high precision and fast manufacturing the scaffold with low costs, so that the scaffold for dental treatment may be immediately placed after tooth extraction and may be accurately placed in a tooth extraction socket. A method of manufacturing a scaffold for treatment of a tooth extraction socket includes manufacturing, by using a three-dimensional (3D) printer, a 3D model comprising alveolar bones and teeth, which are distinguished therebetween, from a medical image file that is a medical image file (DICOM file) of dental computerized tomography (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.
