Abstract: A method includes the steps of preparing a tooth mold of a rollover from a patient's mouse; scanning the tooth mold to convert it into digital data and to create a digital model; conducting operations of at least positioning, integration, and edition of the digital model to create a digital plaster mold; and converting the digital plaster mold through computer-added manufacturing (CAM) into a program for a processing machine and then processing a material with the processing machine based on the program to produce a substantial plaster mold. Accordingly, the present invention can simplify the delivery/transportation process, reduce the costs, speed up the production, and do the standardization.
