Abstract EN
An air turbine handpiece is a dental abrasive device that rotates at high speed and uses compressed air as the driving force.
It is characterized by its small size, light weight, and painless abrading due to its high-speed rotation, but its torque is small and noise level is high.
Thus, to improve the performance of the air turbine handpiece, we conducted a performance test of an actual handpiece and a numerical analysis that modeled the whole handpiece; we also analyzed the internal flow of the handpiece.
Results show that experimental and calculated values were consistent for a constant speed load method with the descending speed of 1 mm/min for torque and turbine output.
When the tip of the blade was at the center of the nozzle, the torque was at its highest.
This is likely because the jet from the nozzle entered the tip of the blade from a close distance that would not reduce the speed and exited along the blade.
