Purchasing Guide: Slow Speed Handpiece


Purchasing Guide Slow Speed Handpiece

When it comes to dental practice, the slow-speed handpiece is an indispensable tool. This dental instrument, equipped with an inbuilt motor, operates within a range that can include speeds from 5,000 to 40,000 rpm and is commonly used for various procedures such as the removal of decay, refining cavity preparations, and performing prophylaxis, to name a few. Our guide aims to provide comprehensive information on purchasing a slow-speed handpiece, considering factors like budget, lifespan, torque, lighting, and maintenance.

Understanding Slow-Speed Handpieces

Slow-speed handpieces, also known as low-speed handpieces in dentistry, are pivotal for a wide array of dental procedures. These handheld devices are engineered to operate at 50,000 RPM or less, making them perfect for tasks ranging from caries removal to prophylaxis and endodontic work. Unlike high-speed handpieces, slow-speed models, such as the NSK slow-speed handpiece or the Midwest slow-speed handpiece, are designed to deliver greater torque due to their ability to handle more air pressure, making them versatile for tasks like polishing and adjustments to prosthetics.

Purchasing Guide: Choosing the Right Slow Speed Handpiece

Slow-speed handpieces come in various models, including the Kavo slow speed handpiece and the Adec slow speed handpiece, and are categorized based on propulsion into air-driven and electric types.

Air-Driven Handpieces

The air-driven slow-speed handpiece, like the Sable or Patterson models, is a staple in the market. Renowned for its precision and lightweight design, the turbine motor in these handpieces typically operates at speeds of 22,000 to 27,000 RPM. They are ideal for a range of tasks, from polishing to endodontic procedures. However, users should be aware of their tendency to overheat and their higher noise levels, which can be a consideration in patient comfort. Despite these factors, air-driven handpieces remain a cost-effective choice, offering benefits in maneuverability and ease of handling.

Electric Handpieces

Electric slow speed handpieces, on the other hand, provide consistent torque and can maintain their performance even under resistance. They are appreciated for their smooth and swift cutting capabilities and are notably quieter than their air-driven counterparts. These handpieces, which can include the electric slow speed dental handpiece, are equipped with a motor and various attachments like the slow-speed contra-angle handpiece or the slow-speed straight handpiece, enhancing their versatility. While they may be heavier, potentially leading to fatigue, their ergonomic design and the steady power they offer make them suitable for a variety of dental tasks, including caries removal and adjustments to bridges and crowns.

The choice between air-driven and electric slow speed handpieces, such as the W&H slow speed handpiece or the Lares slow speed handpiece, will depend on the dentist’s specific needs and preferences.

Factors to Consider When Purchasing a Slow Speed Handpiece

Selecting a slow-speed handpiece, whether it’s a cordless slow speed dental handpiece or one that requires a low-speed handpiece adaptor, involves several critical considerations to ensure value for money and to enhance practice efficiency and patient satisfaction.

  • Budget: The price of slow-speed handpieces, such as the NSK slow speed handpiece price or the low-speed handpiece cost, varies. Assess your budget and the long-term value, keeping in mind that financing options are available to help balance cost with quality.
  • Lifespan and Maintenance: Known for durability, slow-speed handpieces like the Star dental slow speed handpiece or the Lynx model require regular professional maintenance, typically every 6–12 months, to ensure longevity and performance.
  • Lighting: Good visibility is key in dental treatments. Handpieces with integrated lighting, like certain models of the dental slow speed handpiece with light, offer better visibility and ease of use.
  • Propulsion: Choose between air-driven or electric based on your preference, with options ranging from the Midwest slow speed handpiece to the electric slow speed handpiece.
  • Torque and Speed: The slow speed handpiece rpm is a critical factor, especially when considering the specific dental procedures you perform.
  • Comfort and Ergonomics: Comfort is paramount. Test new handpieces, such as the Titan slow speed handpiece or the friction grip slow speed handpiece, to ensure they fit well with your practice’s ergonomics.
Factors to ConsiderDescription
BudgetConsider your budget and the value you’re getting for your money. Look for financing options if necessary.
Lifespan and MaintenanceChoose a handpiece known for its extended lifespan and ease of sterilization.
LightingOpt for handpieces with built-in lights for improved vision.
PropulsionDecide between air-driven and electric propulsion based on your specific needs and preferences.
Torque and SpeedConsider the torque and speed of the handpiece based on the specific procedures you perform.
Comfort and ErgonomicsEnsure the handpiece is comfortable to hold and use for your team members.

Remember, the right slow speed handpiece can significantly enhance your practice’s efficiency and patient satisfaction. Therefore, take your time to consider these factors before making a purchase.


Investing in a slow-speed handpiece is a strategic decision for any dental practice. With the right considerations—taking into account factors from the slow speed handpiece function to the type of slow speed handpiece burs used—you can choose a tool that not only meets your needs but also enhances patient outcomes and your practice’s reputation.

What should I consider when choosing between an air-driven and an electric slow speed handpiece?

When choosing between an air-driven and an electric slow speed handpiece, consider the weight and comfort for prolonged use (air-driven are typically lighter), the noise level during operation (electric are usually quieter), the consistency of torque and cutting power (electric offer steadier torque), and your budget (air-driven are generally more cost-effective). Brands like NSK, Kavo, and Midwest offer various models to suit different needs.

How often do slow speed handpieces need maintenance, and what does it involve?

Slow speed handpieces should undergo professional maintenance every 6–12 months. Maintenance typically involves cleaning, lubricating, and replacing worn parts like O-rings and bearings. Some models, like the NSK slow speed handpiece, may have specific maintenance guidelines, so always refer to the manufacturer’s instructions.

Can I use the same burs for both high-speed and slow-speed handpieces?

No, high-speed and slow-speed handpieces generally require different burs due to the variance in RPM and torque. Slow speed handpiece burs are designed to withstand different pressures and speeds, so using the correct type is crucial for effective and safe dental procedures.

What is the typical lifespan of a slow speed handpiece, and how does it compare to high-speed models?

The lifespan of a slow speed handpiece can vary based on the frequency of use and adherence to maintenance schedules. Slow speed handpieces often have a longer lifespan than high-speed models due to their lower operating speeds and robust design. With proper care, a slow speed handpiece can last for several years.

Are there financing options available for purchasing slow speed handpieces?

Yes, many suppliers offer financing options for purchasing slow speed handpieces. This can include payment plans or leasing options, making it easier for dental practices to acquire quality equipment without a significant upfront investment. Providers like Henry Schein and Patterson Dental often provide such financial services.
