Description

Technical Field

[0001] The utility model relates to the field of dental medical equipment, in particular to a dental resin carving former. Background Art

[0002] Dental caries is a common disease in which the tooth substance is corroded, softened, discolored, and gradually develops into a defect in the tooth hard tissue, forming a cavity. The conventional treatment for dental caries is to fill the cavity with restorative materials. The commonly used restorative materials are resin restorative materials. The process of filling the cavity with resin restorative materials is roughly as follows: clean the cavity, then fill it with resin restorative materials, use a resin carving knife to shape the resin restorative material, and then solidify it.

[0003] The existing resin engraving forming knife has a structure such as Figure 1 As shown, it includes a knife handle and a flat knife head arranged at the end of the knife handle. After the caries cavity is filled with resin, the flat knife head is used to extrude and trim the resin repair material, and the resin repair material is shaped to form a restoration. However, when the existing flat knife head is used to shape the resin repair material, it is impossible to make the entire surface of the resin repair material smooth, and it is easy to produce local protrusions or unevenness. The surface of the resin repair material is difficult to be flat and smooth. Subsequent grinding and polishing procedures must be relied on to make the restoration formed by the resin repair material meet the smooth texture requirements. This process will take a lot of operation time and affect the repair efficiency. Utility Model Content
