Embodiment 1

[0025] Example 1, such as Figure 1-3 As shown, a dental implant fixed bridge device for fatigue and tensile tests, which includes a double-ended fixed bridge 1, a base 4, an abutment 5, and an analog 6, and the double-ended fixed bridge 1 and the abutment 5 are bonded The abutment 5 and the analog 6 are connected by a central screw, and the base 4 and the analog 6 are fixed as one. The double-ended fixed bridge referred to in the present invention refers to the three crowns between the mandibular second premolars and the second molars. The occlusal surface of the double-ended fixed bridge adopts the normal anatomical occlusal surface of the corresponding tooth position, and each crown buccal and lingual side of the double-ended fixed bridge is designed with a retention hole protrusion 12, and the retention hole protrusion 12 is The retention hole 11 is processed, and a stretching fixture 2 and a pull hook 3 are designed. The hook end 31 of the pull hook 3 matches the retenti...

Abstract

The invention relates to an oral implant fixed bridge device for a fatigue and tensile test. The oral implant fixed bridge device comprises a rigid fixed bridge, a base, a base station and an alternative body. The rigid fixed bridge and the base station are adhered and fixed through an adhesive; the base station is connected with the alternative body; the base and the alternative body are fixed into a whole. A retention hole boss is designed on each dental crown cheek and on the side edge of a tongue of the rigid fixed bridge; a retention hole is processed on each retention hole boss; a tensioning and fixing device and drag hooks are designed; hook ends of the drag hooks are matched with the retention holes and can penetrate through the retention holes; the upper ends of the drag hooks are fixed onto the tensioning and fixing device. The oral implant fixed bridge device provided by the invention has the advantages that the whole stressing is uniform, the oral implant fixed bridge device can be used for the comprehensive fatigue and tensile test, the fixed bridge is enabled to conduct an external fatigue test, a thermal-cooling cycling test and the like, a running-in test can be directly conducted to simulate chewing movement in a mouth, an oral environment is simulated to an extreme, the tested fixed bridge can be used for conducting the tensile test so as to detect the change of an adhesive property of the adhesive after a prosthesis is subjected to a certain fatigue loading test, and an experimental basis is provided for selecting the adhesive clinically.

Description

technical field [0001] The invention relates to the basic research field of oral implantology, in particular to the design of an implant-supported double-ended fixed bridge that can be used for fatigue loading and tensile tests. Background technique [0002] Implant-supported double-ended fixed bridge is one of the common restoration methods in oral implantology. Its biggest advantage is that it reduces the number of implants used and the treatment cost of patients. At present, there are mainly two types of retention methods for implant fixed bridges clinically: adhesive retention and screw retention. The two retention methods have their own advantages and disadvantages, but it is still unclear which method is the best, which needs to be determined according to the specific clinical situation. Su Yucheng and other scholars believe that: in the restoration of implant fixed bridges, adhesive retention is generally the first choice. In this method of retention, the restoratio...
