An image correction design system for an oral and maxillofacial surgery. The image correction design system comprises: a first image data scanning module for scanning to obtain image data of relative coordinate positions of maxillofacial bones, teeth, and soft tissues； a second image data scanning module for scanning image data of a plaster dental impression of a patient； a scanning image correction and comparison module for correcting and comparing the image data from the first image data scanning module and the image data from the second image data scanning module and performing archiving to obtain first archives； an image block calculation module for performing an image layer management and block cutting display of the first archives to obtain second archives； a surgery simulation image design module for inputting a surgery data parameter for the second archives after the image layer management and cut block display, so as to design and establish surgery simulation image files； and an output module for outputting the surgery simulation image files by using a display device.
