An invisible orthodontic treatment method for designing overall movement of teeth based on the morphology of alveolar bones, comprising the following steps: S1, acquiring CBCT data; S2, acquiring STL data; S3, acquiring combined data of complete teeth; S4, reconstructing and restoring to an original occlusion form in the mouth of a patient; S5, adjusting three-dimensional positions of the teeth; S6, performing simulated orthodontic treatment according to the adjustment data of the three-dimensional positions of the teeth; S7, generating a dentition model adjusting sequence; and S8, producing an invisible appliance that meets requirements. By the invisible orthodontic treatment method, accurate morphological data of teeth crowns is acquired by means of a digital dentition model, three-dimensional morphological data of teeth roots and alveolar bones is acquired by means of CBCT, and the two pieces of data are combined for matching. Thus, the positional relationships between the teeth roots and the alveolar bones can be clearly seen in real time in the design of an invisible orthodontic treatment scheme and in the generation of the dentition model sequence simulating the movement of teeth, the problems of fenestration, dehiscence, and obvious absorption of tooth roots caused by close collision between the teeth roots and the alveolar bones are avoided.
