Abstract : The high-speed dental air-turbine handpiece is widely used in cutting and polishing denture structure in
dentistry. The handpiece has the air-turbine which rotates a cutting bur. The air-turbine impeller is rotated by the
compressed-air. There are different blade types for the impeller such as flat, concave and gull. The gull and concave type
impeller blades were selected for the air-turbine. The objective of the study was to investigate the flowfield of the air-turbine
with the gull and concave types impeller blade and to compare the results. The computational domain of the air-turbine was
computed usingANSYS CFX Computational Fluid Dynamics (CFD) software. The air-turbine with the concave and gull
type impeller blade was analyzed and the results were evaluated by the velocity, pressure and the torque. The air-turbine
with the concave type impeller blade had higher torque value than the air-turbine with the gull type impeller blade.
Keywords— CFD, concave type blade, gull type blade, impeller, ANSYS CFX, immersed solid.
