The application discloses a preparation method of a bite plate based on a force-induced luminescent material. It belongs to the technical field of oral bite plates and can prepare a bite plate capable of directly and real-timely converting bite force into a visible light signal through a simple process, so that the visualization and semi-quantitative detection of bite contact are realized. The preparation method of the bite plate based on the force-induced luminescent material is characterized in that the method comprises the following steps: (1) synthesizing europium / dysprosium co-doped strontium aluminate force-induced luminescent material SAOED by using a high-temperature solid-phase method, wherein the doping concentration of europium is 2%, and the doping concentration of dysprosium is 1%; (2) mixing the SAOED powder obtained in the step (1) with denture powder according to a mass ratio of 1:7, adding ethanol for dispersion and grinding; (3) adding denture water in a proportion corresponding to the denture powder to the mixture in the step (2), uniformly stirring, and then performing compression molding; and (4) performing water bath heating solidification on the compression molded material, and then performing polishing to obtain the bite plate.

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.

The invention relates to the technical field of oil and gas exploitation, and particularly provides a clamping tong assembly and tubular column clamping equipment. Wherein the clamping pincer assembly comprises a mounting frame and clamping pincers; the clamping pincers comprise two pincer arm structures which are oppositely arranged, and the two pincer arm structures are connected to the mounting frame in an opening and closing mode; the clamp arm structure comprises a clamp arm body and a first tooth plate, the inner side of the clamp arm body is inclined inwards in the gravity direction, and the first tooth plate is movably arranged on the inner side of the clamp arm body in the inclined direction. According to the clamping device, when the clamping forceps clamp the pipe column, the gravity of the pipe column can be transmitted to the first tooth plate and converted into downward component force in the inclined direction, and therefore the first tooth plate is pushed to slide downwards and be tightly attached to the surface of the pipe column. Therefore, the heavier the pipe column is, the stronger the gliding trend of the first tooth plate is, and meanwhile, the occlusal force (abutting pressure) of the first tooth plate and the pipe column is also larger, so that the self-adaptive adjustment of the large clamping force of the heavy object and the small clamping force of the light object is realized, and manual intervention or complex hydraulic feedback control is not needed.

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.
