Dantal Micromotor

1.What is Dental Micromotor?

The electric dental micromotor unit can polish or cut. The handpiece is driven by an electric motor in the handle. The polishing cup, or bur, can variably rotate from 0 to 50,000 rpm and go forward or reverse. It provides very high torque. The handpiece can take a prophy angle, with polishing cups, or a contra-angle, with various attachments, including RA burs and polishing cups. Only a few units have a water-cooling facility.

3.How to choose a perfect dental micromotor

Dental micromotors are utilized in dentistry for the treatment of semihard dental tissues. This instrument is associated with the hoses of other dental instruments with a variable association framework. Various velocities and torques are likewise factors, meanwhile, two various sorts of instruments can be put onto micromotor united: straight and contra-edge handpieces.
 

3.1.1 Micromotors for contra-edge handpiece:

The state of these handpieces forms an edge as for the flat, which encourages access to the mouth. Here the micromotor is joined to the handle, and at the opposite end, different burs are placed depending on the requirement for every circumstance.

3.1.2 Straight handpiece micromotors:

In this case, the state of the instrument is straight, and its essential use is for medical procedures on third molars and modifying of dental prostheses. The hoses are put at the opposite finish of the micromotor and the micromotors have a controller of speed and of the revolution's course. Notwithstanding this, these micromotors can be either pneumatic or electric, the most widely recognized being the pneumatic ones.
 

3.2 Air drive system VS electric drive system. 
There are two systems for driving the needle: Air drive system and an electric drive system. 
Here we recommend the use of electric motors for electric systems that are more in line with current and future commercial use trends.

The pneumatic motor drives the needle indirectly through the contra-angle handpiece or the straight handpiece. The maximum speed that the air motor can reach is 25,000 rpm. The contra-angle handpiece can be used at various speed-up and speed-down ratios. The air motor is equipped with a contra-angle handpiece with a 2:1 reduction ratio, and the speed reached at this time is about 12,500 rpm

5.Dental micromotor speed
At present, for dentists, the highest possible use is 80,000RPM. Of course, this has high technical requirements for doctors and machines. Generally speaking, the operating speed of 40,000RPM is a relatively high operating speed, and the higher the speed, the more delicate operation is required. For some special cases, in order to reduce the pain of dental patients, the dentist will reduce the speed to 100RPM. Therefore, the speed of the dental grinder usually supports the range from 100RPM to 40,000RPM
