Problems solved by technology

[0002] The application of metal posts in oral restoration technology has a history of more than half a century. It is mainly used to insert into the root canal to make the restoration have a good fixed position. Metal posts have long been an important technical means in defining tooth restoration. The metal studs are usually screwed into the alveolar with the help of a screwdriver. In the existing operation method, the screwing of the metal studs is inconvenient and easy to tilt, making the diameter of the hole larger than the diameter of the metal studs, which cannot achieve the proper fixation and correction.

Abstract

The invention discloses a metal post nail fixing device for the department of prosthodontics. The metal post nail fixing device for the department of prosthodontics comprises a cylinder; a storage battery is mounted at the right end of the outside surface of the cylinder; a control switch is mounted on the side surface of the storage battery; an input end of the control switch is electrically connected with an output end of the storage battery; a left opening of the cylinder is connected with a cavity pipe. The metal post nail fixing device for the department of prosthodontics is simple in structure and convenient to hold, and can drive a metal post nail into a tooth socket; tapping power can be provided by utilizing a servo motor; the rotating speed is controlled precisely and stably; soft tissue clamping and a rejection reaction caused by improper speed control in a manual operation are avoided; a clamping plate can support a rod part of the metal post nail and is recycled after thetip of the nail is screwed into the tooth socket; rod part movement caused when a nail cap of the metal post nail is stressed is avoided; the aperture of a hole is effectively prevented from being greater than the metal post nail; the stability after the metal post nail is fixed is improved; required correcting and supporting effects are ensured; the metal post nail fixing device for the department of prosthodontics is convenient to use.
