  • Performance and Internal Flow of a Dental Air Turbine ...

    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 ...

    For cranial window implantation, a small island of bone is replaced by a coverslip of up to 5 mm in diameter. To achieve this, a dental drill is used to carefully cut the perimeter of the craniotomy until the “moat” is thin enough to split locally under slight pressure. The perimeter needs to be fractionally smaller than the diameter of the circular glass coverslip (Warner Instruments, Hamden CT).
