Description

Technical Field

[0001] The utility model belongs to the field of dental implantation, in particular to an automatic clip-on dental composite bonding base. Background Art

[0002] The composite bonding abutment is a product for dental restoration. Its main function is to be used for the crown abutment of denture restoration after dental artificial root implant surgery. The traditional crown abutment needs to have the central screw for fastening replaced regularly. When replacing, the crown sealing glue needs to be polished with a dental mobile phone to expose the central screw interface so that the screw can be screwed out. During the polishing and sealing process, microparticles and debris are easily generated, causing oral discomfort to the patient. The polishing of the sealing glue takes a long time, and after replacing the central screw, the screw hole needs to be sealed with glue. During this process, the patient needs to open his mouth for a long time, causing patient fatigue. The doctor's operation is also cumbersome. Utility Model Content
