The present invention relates to a wrench mechanism for implant procedures, and more particularly, to prevent damage to the skin of the mouth or the skin of the mouse portion during the implant procedure for the teeth in the oral cavity, especially the tooth deeply located in the oral cavity, The present invention relates to an implant surgical wrench mechanism configured to secure a surgical field of view and a surgical working space to enable a precise, stable and safe operation for a patient.

A dental implant is an artificial replacement of a damaged or lost natural tooth itself, or a screw-shaped artificial dental fixture is fastened to the alveolar bone to allow it to fuse with the bone for a period of time, and then to the junction thereon. By abutment (abutment) means a dental procedure for fixing the prosthesis, such as artificial teeth (crown).

Artificial dental fixtures or screws for fixing abutments, which are used in such dental implant procedures, are classified into products with various apertures and screw pitches, depending on the purpose and function. Fastening mechanisms such as wrenches are used.

1 shows a wrench for such a prior art implant procedure.

The implant surgical wrench of FIG. 1 has a structure in which a shaft portion is attached to a head portion 1 on which a fastening hole 1a is formed, and the shaft portion includes two first and second shafts 2a, 2a ', 3a extending in parallel; 2b, 2b ', 3b), an intermediate connecting pin 4 for connecting the first and second shafts between the first shaft and the second shaft in the middle portion of the shaft, and the head portion 1 from the position of the intermediate connecting pin 4; Among the first and second grip shafts 3a and 3b, which are shaft portions extending in the opposite direction of the crankshaft, it is composed of a protruding elastic strip 5 attached to any one of the opposing surfaces to provide an elastic force.
