Description of the Invention: [Technical Field] The present invention relates to a locking wedge pin type pillar body, and more particularly to a locking wedge pin type pillar body having a weakened zone. [Prior Art] Referring to the drawings, which show a conventional locking wedge pin type pillar body and a dental implant body, with reference to Fig. 2, a conventional locking wedge pin type pillar body and a dental implant body are shown.

The connection of the 楔ockmg taper is a connection method for the dental implant. The conventional locking wedge pin type strut body (7) includes a first portion 11, a second portion 2, and a third portion 3. Conventional dental implants include an opening 2]. When the wedge-shaped strut body 10 and the dental implant body 2 are locked, the first portion 11 of the strut body 10 is conical, and the angle b is larger than the angle of the opening 21 of the dental implant 2〇. The structure of a, when properly sized, produces an effective locking bond. The utility model has the advantages of simple structure and convenient operation; and good bacterial sealing property, and it is not easy to generate odor after the patient device. Referring to Figure 3, there is shown a schematic view of a conventional locking wedge pin type strut body fracture. Since the first portion of the pillar body accommodated by the smaller-sized dental implant 20 is also small, it is clinically seen that the pillar body 10 is broken. Since the fracture is likely to occur near the upper end of the opening 21 of the dental implant 20, the first portion of the opening 2 of the residual implant 20 after the fracture is not directly clipped by the instrument. It must be taken out after drilling through the residual first portion η, so that it is not only increased: clinical difficulty □ and if the inner wall of the dental implant 20 is damaged, the bacterial closure property is also destroyed. ]54084.doc m

The invention provides a lock with a weakened zone, a lock, a wedge pin type support body, including a first part, a second part and a Included · #解认Π: One point. This first part is used to place the weight in one of the openings of a dental implant. I π is used for sub-division, the second part of n 5 hai is connected to the first part of the rupture occurs in the "broadcasting" wedge-shaped pin-shaped pillar body. The third part of the weakened zone 1 is connected to the second part for Connect a copy. By using the locking wedge pin type of the present invention, there is no cylinder in your year, since the second part is not connected to the opening of the dental implant or the smashing material (such as a denture), and the weakened area is utilized by the structure, so that The locking wedge pin shows that the possible break of the gram cylinder occurs here. The second part of the knives remaining after the rupture is larger than the opening of the dental implant, so the second part of the residue can be used _ crying mouth. The direct directing of the machine can greatly reduce the difficulty of clinical operation, and it is not worth mentioning that it will damage the inner wall of the dental implant and will not block the bacteria. [Embodiment] The "upper" and "reverse" of the sputum that is connected to the future are not related to gravity. "Upper" is the occlusal surface or the cut end of the table, and "Bottom" is the schematic diagram of the locking mode of the Xiaotang pillar body and the dental implant with the weakened zone of the present invention.
