Air-driven high-speed handpieces provide higher speeds but lower torque than electric handpieces. Power from air-driven handpieces is delivered to the bur via a turbine regulated by air less than 30 to 45 pounds per square inch. These handpieces generally operate at speeds between 250,000 rpm and 420,000 rpm (and decrease in speed when they meet resistance).
Depending upon the size of the head (mini-head, standard, and high-torque), air-driven handpieces provide 12 to 18 Watts of cutting power (torque). Mini-heads offer nearly 14 Watts of torque, and are ideal for pedodontic restorations, endodontic access, and treatment of second or third molars. Standard heads are considered effective overall handpieces, and are useful for crown and bridge preparation, and most other treatments performed in average practices. They provide 15 to 17 Watts of power, but need greater clearance than mini-heads, and tend to obscure more of the field. High-torque heads, with almost 18 Watts of torque, are indicated for tasks such as removing nonprecious crowns or heavy amounts of crown and bridge.
The 4-hole connector has been standard for air-driven handpieces, and manufacturers have now introduced quick-disconnect couplings to enable recommended autoclaving of the handpieces between patients.
So, you’re interested in buying a new handpiece and you’re currently weighing your options—literally. Perhaps you’re gravitating towards an air-driven model for its lighter weight, which lends itself to better ergonomics and balance. However, there are some things you should consider before you make your purchase. As noted in a comparison chart...
What do you use in your practice? Are you strictly an air-driven dentist or electric? Or do you feel comfortable using both? Whatever your preferences, it doesn’t hurt to be reminded of the advantages and challenges of both. After all, your handpieces are probably the most used equipment in your office. Air-Driven Handpieces As you’re probably...
Convert it to an electric handpiece! Some of the advantages to electric handpieces that have been noted include that they operate at both high and slow speeds, they have high constant torque, low volume, versatility, enhanced control, increased precision, they are lighter weight, and they run quieter. The NLZ from NSK can convert air-driven...
