Denture Processing and Polishing

I、 Why polishing is needed

After the denture is processed, there are usually some rough or uneven defects on the surface, which will 

affect the beauty and comfort of the denture, and will also increase the friction between the denture and 

the oral tissue, causing oral discomfort in patients. Polishing is to remove these defects, make the denture 

surface smooth and bright, and improve the comfort of patients.

II、 Preparation before polishing

Before polishing, some preparations need to be made:

1. Prepare the polishing machine and tools: including motors, polishing wheels, polishing paste, etc.;

2. Check the denture surface: Check whether there are defects or uneven places on the denture surface, 

and polish if necessary;

3. Cleaning: The denture needs to be cleaned before polishing to ensure that there is no dust or impurities 

on the surface.

III、 Polishing steps

1. Rough grinding: Use rough grinding wheels and abrasives to remove surface flaws and uneven areas;

2. Medium grinding: Use medium grinding wheels and abrasives to further polish the surface to make it 

smoother;

3. Fine grinding: Use fine grinding wheels and abrasives to finally polish the surface to achieve the best 

finish;

4. Polishing: Use polishing wheels and polishing paste to polish the denture surface to make it smoother 

and brighter;

5. Cleaning: Clean the denture to remove residual impurities and abrasives on the surface.

IV、Precautions

1. Selection of polishing wheels and abrasives: should be selected according to the material of the denture 

and the polishing effect 

to be achieved;

2. Polishing time and pressure: should be determined according to the size, material and polishing steps of 

the denture;

3. Apply force evenly during polishing to avoid unevenness;

4. During the polishing process, the denture surface should be constantly checked to ensure the desired

polishing effect is achieved.

In short, polishing is a very important part of the denture processing process. It can not only improve the 

beauty and comfort of the denture, but also increase the service life of the denture. When polishing, you 

need to pay attention to choosing the right polishing wheel and abrasive, polishing time and pressure, and 

pay attention to evenly applying force and constantly checking the denture surface.
