2.How to use 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.
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.
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.
