Hexa driver with safety wire for implant surgery

According to the present invention, one end of the safety wire is rotatably coupled to the adapter into which the body of the driver body is inserted, and the other end is coupled to an external support object to prevent swallowing accidents of the hexa driver and safety wire regardless of the rotation of the driver body. It is about a hexadriver for implant surgery equipped with a safety wire that is convenient to use because there is no twisting.

Dental implant prostheses are intended to replace lost natural teeth. In order to support and fix the implant as a whole, a fixture, which is an artificial root, is placed in the alveolar bone in the area where the tooth is lost, and a healing abutment is placed on the top of the fixture. It is necessary to combine the healing abutment to allow the fixture to be fused and adhered to the alveolar bone.

After that, the healing abutment is removed, and the abutment (abutment, abutment) is combined and installed to be exposed to the upper part of the gums, and then the crown is connected to the abutment.

In this series of processes, when fastening or removing the healing abutment, or when fastening the abutment screw, the hexa driver 10 shown in FIG. 1 is used.

Such a hex driver corresponds to a very small device. Therefore, if the operator misses the hexadriver during the procedure, the hexadriver may fall into the patient's mouth and swallow it.

In order to solve this problem, in the prior art, one end of a wire such as dental floss or a ligature wire was tied to the hexa driver, and the other end of the wire was tied to the patient's teeth or the operator's hand to prevent swallowing accidents of the hexa driver.

However, in this case, when the hex driver is rotated, the wire is twisted, making it inconvenient to use the hex driver.
