Low speed dental handpieces, also known as slow phones, are classified as Class II medical devices according to the Classification Catalogue of Medical Devices due to their lower rotational speed compared to high-speed phones.

The low-speed dental handpiece is divided into two parts, one is the motor and the other is the phone body. When using it, the motor needs to be installed on the dental chair first, and then the low-speed dental handpiece needs to be installed on the motor. Then, the needle is installed, and the foot pedal is used to control rotation and stop for operation.

Low speed dental handpieces are divided into straight and curved machines. Straight machines are used for polishing outside the mouth. When there is no specialized polishing machine at hand, we use them to polish dentures or temporary crowns. The needles used are commonly referred to as grinding heads, which are generally the same as the 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 will be difficult to clean.

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

We still remember that high-speed dental handpieces are called high-speed gas turbine phones, which spin and release water and air at the same time. The speed is very fast, and bending machines usually do not use water because they have different purposes.

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 opening the pulp. Our G drill, P drill, and polishing cup are also installed on low-speed dental handpieces, used for polishing after tooth cleaning, removing the dental glue tip, preparing the fiber pile channel, and other operations. Usually, it does not require water spraying, so low-speed dental handpieces generally do not have a water path, or use an external water path design, We should be careful not to step on the water pedal when stepping on it, otherwise the water will spray everywhere.
