Claim:
1. A method of manufacturing a surgical template positioning device, comprising steps of: preparing a dental mold from a patient, wherein the dental mold has a simulation prosthetic tooth and at least three spherical portions formed on a platform of the dental mold and surrounding the simulation prosthetic tooth; wearing the dental mold on gums of the patient and performing a tooth computed tomography on the dental mold and the alveolar bone of the patient, so as to obtain data of the patient and the dental mold; providing a template having at least three spherical recesses on a first surface, wherein the spherical centers of the at least three spherical recesses define three vertices of a triangle, and the at least three spherical portions have spherical centers corresponding with the three vertices of the triangle; digitally planning an implanted hole for the dental mold and a guiding hole for the template having an axis and coaxially aligned with the implanted hole according to the data of the patient and the dental mold; forming the guiding hole passing through the template according to the triangle and the axis; removing the simulation prosthetic tooth from the dental mold; combining and fixing the template with the dental mold; and forming the implanted hole passing through the dental mold by using the guiding hole of the template.
