Low speed mobile phones are also known as slow machines because of their lower rotational speed compared to high-speed mobile phones. According to the Classification Catalogue of Medical Devices, they belong to Class II medical devices.

The low-speed mobile phone is divided into two parts, one is the motor, and the other is the body of the phone. When using it, it is necessary to first install the motor onto the dental chair, then install the low-speed mobile phone onto the motor, and then install the needle. Use the foot pedal to control rotation and stop, for operation.

Low-speed mobile phones are divided into straight machines and bending machines. Straight machines are used for grinding out of the mouth. When there is no special polishing machine at hand, we use them to polish dentures or temporary crowns. The needles used for it are commonly referred to as grinding heads, which are generally common to grinding heads of grinding machines.

If there is a lot of polishing required and there is a specialized technician room, it is best to stay in the technician room, otherwise debris flying everywhere is difficult to clean.

The bending machine is commonly used when we operate in the mouth. Before using it, we need to install a needle, remove the paddle on the back, insert the needle, and then buckle the paddle back. Check to see if it is fastened, and then we can use it. The same operation is also used when disassembling.

We still remember that high-speed mobile phones are called high-speed gas turbine mobile phones, which are very fast in rotating, water flowing out, and air flowing out. Bending machines usually do not use water because of their different uses.

The bending machine can be used to remove decay during tooth filling, or to lift and remove the top of the pulp chamber with a small ball drill after pulp opening. Our G drill, P drill, and polishing cup are also installed on low-speed mobile phones, which are used for polishing after tooth cleaning, removal of the dental glue tip, preparation of fiber post channels, and other operations. Generally, it does not require water spraying, so low-speed mobile phones generally do not have a water path, or use an external water path design, When we step on our feet, we should be careful not to step on the feet of the waterways, otherwise the water will spray everywhere.
