For more than half a century, dental turbines have been used in clinical centers but little research has been done on how they work. Dental turbines are one of the most used equipment in dentistry and dental clinics. Achieving high speeds helps the dentist to reduce the duration of treatment, reaching a smooth surface, and high precision for the expected anatomy. In rotor dental cartridges, there is a significant effect on the reduction or increase in circumference.
In the present work, the original samples of different rotors were scanned using a digitizer then it was modeled using reverse engineering design software then simulation was performed and the effect of different parameters was investigated. In dental turbines, rotors can have different shapes that has major impact on torque, rotational speed and power. For this purpose, a propeller model was simulated and analyzed. The results show that the diameter of the impeller and the shape of the blade have a great influence on the torque and turbine performance.
The geometric shapes of the turbine cartridges are varied and sometimes complex to increase speed and efficiency that these complex forms make them more expensive and require advanced devices in their production. We used 3D printers, Laser machine, Water jet machine, Wire cut device, CNC turning machine and CNC four-axis milling to produce rotors
