Abstract

The invention discloses a metal post pin fixing device for the prosthodontics department. The metal post pin fixing device comprises a tooth holder; the tooth holder is in an arc shape; a tooth socketvertically through is formed in an inner cavity of the tooth holder; a plurality of screw holes are formed in each of the front side and the rear side of the outer wall of the tooth holder equidistantly; an arc-shaped sliding groove is formed in the inner wall of the tooth socket in the left-right direction; a hollow box is assembled in an inner cavity of the tooth socket; a rolling wheel embedded in an inner cavity of the arc-shaped sliding groove is assembled on the outer wall of the hollow box; and a feeding mechanism is detachably assembled at the top end of the hollow box. According to the metal post pin fixing device, a metal post pin can be fixed through a fixing unit, and can be installed on the hollow box; a housing is installed on a fixing unit to make a polygonal rod correspondto a polygonal hole in the metal post pin; the feeding mechanism makes the metal post pin rotate around the metal post pin and move downwards to enter a false tooth, and the metal post pin is convenient to screw in; and the metal post pin fixing device not only is time-saving and labo-saving, but also is not prone to incline, thus guaranteeing the fixing and correcting effect.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a metal post and nail fixing device for dental restoration. Background technique [0002] The application of metal post 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 post nails have long been an important technical means in defining tooth restoration. In the existing operation method, the metal post is usually screwed into the alveolar with the help of a screwdriver. The screwing of the metal post is inconvenient. Contents of the invention [0003] The purpose of the present invention is to provide a metal peg fixing device for dental prosthodontics to solve the problems of inconvenient screwing and easy tilting of metal pegs proposed in the background art. [0004] In order to achieve the above object, the present invention provides the follow...
