PURPOSE: A teeth calibration data generating device for manufacturing transparent braces is provided to insert a standard moving figure with teeth in one body and adjust the standard figure. CONSTITUTION: A teeth calibration data generating device comprises a calibration data generating unit(10) which generates a patient's calibration data for transparent braces falling into several steps according to the change of the tooth arrangement with the calibration treatment of the patient's present teeth data; a simulation unit(20) generates a simulation data for preparing the patient's outline data before and after the calibration procedure based on the generated teeth calibration data; a database(30) stores and manages the outline data of the before and after calibration and guide information guide.
