The Multiplier Contra-angle and the Turbine are both types of dental handpieces that have their own unique features and benefits. Here are some of the benefits of the Multiplier Contra-angle compared to the Turbine:

1. More power: The Multiplier Contra-angle provides more power than the Turbine, making it a better option for procedures that require higher torque, such as removing old restorations or preparing a tooth for a crown.
2. Reduced vibration: The Multiplier Contra-angle has a gear system that reduces vibration, making it more comfortable to use for both the dentist and the patient. This is particularly useful for longer procedures that require prolonged use of the handpiece.
3. Increased control: The Multiplier Contra-angle allows for more precise control due to its slower speed and higher torque. This can be especially beneficial for procedures that require fine and delicate work, such as shaping and polishing a tooth.
4. More durable: The Multiplier Contra-angle has a longer lifespan compared to the Turbine due to its more robust design and materials. This means that it requires less maintenance and replacement, which can save money and time in the long run.
5. Quieter operation: The Multiplier Contra-angle operates more quietly than the Turbine due to its gear system, which reduces noise and makes it more comfortable for patients.

In summary, the Multiplier Contra-angle offers more power, reduced vibration, increased control, increased durability, and quieter operation compared to the Turbine. However, the Turbine is often more affordable and can still be a suitable option for many dental procedures. Ultimately, the choice between the two depends on the specific needs and preferences of the dentist and the nature of the procedure being performed.
