A method for forming and setting a denture has the following steps: using a stereoscopic scanner to capture a patient's maxillary, mandibular gum shapes to generate stereoscopic maxillary, mandibular gum data and an occlusion record of a patient's maxilla and mandible； using a computer tomography scanner to scan patient's maxilla, mandible shapes to generate tomographic maxilla, mandible data； using a 3D processing device to consolidate the stereoscopic maxillary, mandibular gum data, occlusion record of a patient's maxilla and mandible, tomographic maxilla, mandible data to generate 3D full-tooth data； planning detailed positions and sizes of a upper (lower) prosthesis adapted to set on the patient maxilla (mandible) side, a plurality of upper (lower) fixing elements for fixing the upper (lower) prosthesis through the 3D full-tooth data； and making the upper, lower prostheses, and using each upper (lower) fixing element to implant the upper (lower) prosthesis into the patient's maxilla (mandible).
