Computational Approach To Design The High-Speed Dental Air-Turbine Handpiece
The high-speed dental air-turbine handpieces are widely used in the dentistry as a tool for cutting and drilling a tooth. The advanced existing high-speed dental air-turbine handpieces were investigated to design the high performance dental air-turbine handpiece. The coupler and air-turbine of the dental air-turbine handpiece was designed using computational analysis. The computational domain of the air-turbine was investigated using ANSYS CFX software. The prototype of the designed handpiece was manufactured and the results were verified through the measurement and the pre-clinical test. The results showed that the newly designed handpiece had no significant difference in performance when compared with other existing advanced dental handpieces.
