Abstract
Description
Technical Field
[0001] This utility model relates to the field of resin tooth polishing and grinding, specifically a multi-stage grinding head assembly for polishing composite resin tooth surfaces. Background Technology
[0002] Resin teeth are mainly made of methyl methacrylate, which has moderate hardness, similar shape and color to natural teeth, is not easy to break, and has good bonding with the base material. Anatomical modification and polishing are very convenient. Composite resin teeth are a dental restorative material composed of high molecular resin materials and inorganic fillers. They are mainly used for clinical treatments such as tooth defect repair, cosmetic restoration and veneers. Its core components are resin matrix, inorganic fillers, photoinitiators and colorants. They are made into restorations such as crowns, bridges or inlays through molding or injection molding processes.
[0003] Composite resin teeth can be customized to match the color and transparency of natural teeth, making them particularly suitable for anterior tooth restorations and achieving a lifelike effect. Composite resin teeth do not require high-temperature sintering; they harden rapidly through light curing, shortening chairside operation time. However, during the processing of composite resin teeth, polishing and grinding are necessary. Currently, the grinding heads used for polishing composite resin teeth are relatively simple, requiring constant replacement of different grinding wheels, which is cumbersome and reduces the efficiency of polishing the surface of composite resin teeth. Therefore, we propose a multi-stage grinding head assembly for polishing the surface of composite resin teeth to solve the above problems. Utility Model Content
