What are high speed handpieces used for?
The high speed handpiece is a precision device for removal of tooth tissue efficiently and rapidly with no pressure, heat or vibration and cut the tooth like butter. However these handpieces have to be used with caution.
How many rpms are in a dental handpiece?
Reaching speeds as high as 420,000 rpm, high-speed air-turbine dental handpieces may outrun electrics, which generally top out at 200,000 rpm, but they lack the torque of the latter, and have been known to stall under load. In fact, their speed may drop as much as 40% or more once their burs hit a surface.
What is micromotor used for?
What is the speed of a slow handpiece?
Slow speed handpieces and attachments Slow speed dental handpieces are used for removal of soft decay, finishing cavity preparation, polishing, trimming and prophy work. Referred to as ‘slow speeds’, they operate with an inbuilt motor at a typical speed of up to 80,000 rpm.
What is a low speed dental handpiece?
