The invention discloses a method for building a three-dimensional tooth-and-jaw fusion model. The method includes the steps that data is collected in the occlusion state, and a skull CT image is rebuilt, laser scanning of a gypsum occlusion model is subjected to digital processing; picture processing and the image matching function are based on a reverse engineering software Geomagic Studio, a method based on point matching and the iterative algorithm are combined in the reverse engineering software, a gypsum dentition occlusion model and CT rebuilt dentitions are matched, indistinct CT rebuilt dentitions are replaced, and finally, the three-dimensional tooth-and-jaw fusion model matched in the occlusion state that a CT rebuilt jaw model and the gypsum dentition occlusion model are integrated is obtained. CT imaging artifacts caused by intraoral metal and the error, caused by upper-and-lower-jaw dentition overlapping in the occlusion state, between the occlusion relationship and the practical intraoral occlusion position in the fusion model are reduced, and therefore the accuracy of computer aided design and the treating effect are improved.
