How to polish dental medical instruments?Dental medical instruments need polishing. Instruments used in dental surgery need to keep their surfaces smooth to ensure safety and hygiene. Unpolished instruments may have tiny scratches or depressions, which are easy to hide dirt and lead to bacterial growth.
Polishing can remove any defects on the surface of the instrument, make it easier to clean, and can help prevent or reduce the risk of infection of patients. Therefore, polishing is an essential step in the manufacturing process of dental medical instruments.
How to polish dental medical instruments, shapes and uses of the instruments, but usually the following steps can be adopted:
Cleaning the instrument surface: use detergent or decontamination powder to clean the instrument surface and rinse it clean. This ensures that the surface is free of any impurities or residues.
Use abrasive for preliminary polishing: Select appropriate abrasive according to the hardness of the instrument, and then use a grinder or a manual grinding head to preliminarily polish the surface of the instrument. The finer the abrasive, the smoother the polishing.
Use polishing agent for fine polishing: After preliminary polishing, use a soft cloth wheel or polishing brush to dip the polishing agent and polish the surface of the instrument again. Polishing agent may be liquid, paste or powder, and the specific choice should be based on the shape and requirements of the instrument.
Final cleaning and disinfection: After polishing, rinse the instrument with clear water to ensure that no polishing agent or abrasive is left on the surface. Finally, the instrument is disinfected to ensure its hygiene.
It should be noted that before polishing dental medical instruments, it should be ensured that the surfaces of the instruments are carefully inspected for damage or cracks, and if so, they should be repaired or replaced. In addition, when using tools such as polishing agents and abrasives, you should bring protective equipment, such as gloves, protective glasses and masks.
