The application discloses a titanium-zirconium alloy dental implant and a manufacturing method thereof, and belongs to the technical field of biological medical device manufacturing. Three supporting feet are uniformly arranged on the circumference of the small-diameter end of the conical tube along the generatrix direction, which not only ensures the area and stability of the contact between the implant and the jaw bone, but also is beneficial to the growth and tightness of the bone tissue. The hollow tubular structure of the implant body has more than 50% higher bending deformation resistance than the solid columnar structure, effectively ensures the stability of the implant when biting food, and prevents the implant from loosening caused by micro-deformation. The crown base is an important bearing part of the implanted tooth, and in the process of food biting and chewing, the crown body transmits the biting force to the implant body and the jaw bone through the pile of the crown body base. The side wall of the circular table cooperates with the inner hole wall of the large-diameter end of the conical tube, and the convex rib cooperates with the groove, so as to realize the positioning of the crown base and prevent the displacement of the crown base in the circumferential direction.

This invention discloses an intelligent denture modeling device based on oral scan data, relating to the field of dental prosthesis modeling. This device, by setting a light refraction acquisition component for emitting blue light at the end of the scanner and a bite plate on the mounting tube, allows the patient to bite down on the bite plate and exert force when collecting oral data. This puts the oral soft tissues in a stressed state, and the light refraction acquisition component at the front end, in conjunction with the scanner, captures the soft tissue displacement under the biting force, obtaining the patient's oral data under the stressed state. This helps medical personnel obtain functional pressure impressions and improves the accuracy of denture fabrication.
