Description

Technical area

[0001] The present utility model relates to the field of dental equipment, in particular to a device for carving and shaping dental resin. Background technology

[0002] Dental caries is a common disease in which the dentin is attacked, softened, and discolored, gradually developing into a defect in the hard tissue of the tooth, forming a carious cavity. The conventional treatment method for dental caries is to fill the carious cavity with a restorative material. The commonly used restorative material is a resin restorative material. The process for filling the carious cavity with the resin restorative material is roughly as follows: cleaning the carious cavity, then filling it with the resin restorative material, shaping the resin restorative material with the resin carving and shaping knife, and then curing the resin restorative material.

[0003] The existing resin carving and shaping knife, whose structure in Fig. 1 includes a knife handle and a flat cutter head disposed at one end portion of the knife handle. After filling the carious cavity with resin, the flat cutter head is used to extrude and regulate the resin restoration material, and the resin restoration material is shaped to form the restoration body. However, when the existing flat cutter head shapes the resin restoration material, it cannot make the entire surface of the resin restoration material round and smooth, and local convexity or unevenness is likely to occur, so that the surface of the resin restoration material is hardly flat and smooth. It must rely on the subsequent grinding and polishing process to make the restoration body formed by the resin restoration material to the required smooth texture. This process consumes a lot of operating time, which affects the efficiency of the restoration. Content of the invention

[0004] In order to solve the above-mentioned technical problems, the present utility model provides a dental resin carving and shaping device, which can make the surface of the resin restoration material filled in a carious cavity more rounded and smooth, so as to avoid the problem that during the filling stage of the resin restoration material, the surface of the restoration body is uneven and not smooth, thereby impairing the restoration efficiency.
