Because the fracture tends to occur close to the upper end of the opening 21 of the dental implant 20, the first part 11 in the opening 21 of the dental implant 20 after the fracture cannot be directly clipped out by an instrument.
It must be taken out after drilling through the residual first part 11, which not only increases the clinical difficulty, but also damages the inner hole wall of the dental implant 20, and also destroys its bacterial sealing

Embodiment Construction
[0059] In order to have a more complete and clear disclosure of the invention purpose, technical means and technical effects of the present invention, a detailed description is given below, and please also refer to the drawings and component numbers.
[0060] The "up" and "down" mentioned in this article have nothing to do with gravity. "Up" means closer to the occlusal surface or incisal end of the denture that will be attached, and "lower" means the opposite.
[0061] refer to Figure 4 , which shows a schematic diagram of the locking wedge-pin type pillar body and the dental implant with a weakened area according to the first embodiment of the present invention. According to the first embodiment of the present invention, the locking wedge-pin pillar body 30 with a weakened area includes: a first part 31 , a second part 32 and a third part 33 . The first portion 31 is configured to be disposed in an opening 21 of a dental implant 20 , and the first portion 31 is connected ...

Abstract
A locking wedge pin type pillar body with a weakened area, comprising: a first part (31, 41, 51, 61), a second part (32, 42, 52, 62), and a third part (33, 43, 53, 63). The first part (31, 41, 51, 61) is configured to be placed in an opening (21) of a dental implant (20), the first part (31, 41, 51, 61), and the dental implant The body is a threadless connection. The second part (32, 42, 52, 62) connects the first part (31, 41, 51, 61), has a structurally weakened area (321) and a protrusion (322), and the locking wedge type strut The possible fracture of the structure occurs in the structurally weakened area (321), and the protrusion (322) is arranged under the structurally weakened area (321). The third part (33, 43, 53, 63), connected to the second part (32, 42, 52, 62), is used for connecting a denture. The possible fracture of the locking wedge-pin type strut body of the present invention occurs in the structural weakening area (321), and the remaining protrusion (322) can be used to clamp out directly with an instrument, so that the broken locking wedge-pin type strut body The clinical operation of removal is simple and safe, which can greatly reduce the difficulty of clinical operation, and will not damage the inner hole wall of the dental implant, nor will it destroy its bacterial sealing.
Description
technical field [0001] The invention relates to a locking wedge pin type pillar body, especially a locking wedge pin type pillar body with a weakened area. Background technique [0002] refer to figure 1 , which shows a schematic diagram of a known locking wedge pin type pillar body and a dental implant; refer to figure 2 , which shows a schematic diagram of the combination of a known locking wedge-pin type pillar body and a dental implant. A locking taper connection is a connection used for dental implants. The known locking wedge type pillar body 10 includes a first part 11 , a second part 12 and a third part 13 . A conventional dental implant 20 includes an opening 21 . [0003] When combining the known locking wedge pin type pillar body 10 and the dental implant 20, the first part 11 of the pillar body 10 is conical, and its angle b is slightly larger than the angle a of the opening 21 of the dental implant 20. , which can produce an effective locking combination a...
