Description

Dental crown clamp

Technical Field

The invention relates to the technical field of oral medical instruments, in particular to a dental crown clip.

Background

With the improvement of living standard, people have increasing awareness of health care of oral cavities. Because of tooth defect or dentition defect caused by caries, fracture, etc., the prosthesis is needed to restore the function and beauty of the defect part. The fixed prosthesis is one of the important components of the dental prosthesis and mainly comprises a dental crown, an inlay, a veneer and the like. At present, the prosthesis is mainly adjusted and modified and chemically treated by holding the prosthesis by hands, the volume of the dental prosthesis is small, saliva of a patient exists on the surface of the prosthesis when the dental prosthesis is taken out of a mouth of the patient, a doctor is difficult to stably hold the dental prosthesis during adjustment and chemical treatment, the prosthesis is easy to slip from the hands of the doctor, the prosthesis is damaged and polluted when falling to the ground, and the feeling of the patient is not good. When the prosthesis is held by hands, the gloves at the fingertips are easy to roll into the grinding head when the prosthesis is ground, so that the gloves are damaged and finger mucous membranes are damaged; when the prosthesis is polished, heat generated by the grinding head is transferred to the fingers of a doctor through heat generated by the prosthesis, so that the discomfort of the doctor during operation is caused; hydrofluoric acid is needed to be used for chemical treatment before the ceramic inlay and the veneer are bonded, the hydrofluoric acid has strong corrosivity, once the glove is slightly damaged, serious chemical burn can be caused.
