Abstract
High-speed air turbine handpieces have been used as a dental cutting tool in clinical dentistry for over 50 years, but little study has been reported on their performance analysis. Therefore, the effect of turbine blade shape on performance characteristics of dental air turbine handpiece were studied using CFD in this paper. Computations have been performed for five different positions of turbine blade by using frozen rotor method that is one of steady-state method. The characteristics of turbine blade for shapes and reflection angles were analyzed. As a result of the computation, torque is increased by increasing the reflection angle of turbine blade.
