Description

[Technical field]

[0001] The present disclosure relates to the field of dental medical equipment, and more particularly to a type of dental resin sculpture molding tool. [Background technology]

[0002] Tooth decay is a common disease in which the quality of teeth is corroded, softened, discolored, and gradually damages the hard tissue of teeth, forming a cavity. The usual treatment method for tooth decay is to fill the cavity with a restorative material, and the commonly used restorative material is a resin restorative material. The process of filling the cavity with a resin restorative material is as follows: after cleaning the cavity, fill it with a resin restorative material, use a resin engraving and molding cutter to mold the resin restorative material, and then harden it. Summary of the Invention [Problem to be solved by the invention]

[0003] However, the conventional resin carving and molding cutter has a structure including a handle and a flat cutter head installed at the end of it, as shown in Figure 1. After filling the cavity with resin, the resin restorative material is extruded and adjusted with the flat cutter head, and the resin restorative material is molded to form a restoration. However, when molding the resin restorative material with the conventional flat cutter head, the entire surface of the resin restorative material cannot be made smooth, and localized protrusions and unevenness are generated, making it difficult to make the surface of the resin restorative material flat and smooth, and it is necessary to grind or polish it afterwards, which takes a lot of operation time and reduces the efficiency of the restoration.

[0004] Therefore, in order to solve the problems of the existing technology described above, the present utility model provides a dental resin engraving and molding tool that makes the surface of the resin restorative material filled into the cavity smoother and avoids the problem of unevenness or lack of smoothness on the restoration surface affecting the restoration efficiency during the filling stage of the resin restorative material.
