In a field where every millimeter matters, the tools a dentist chooses can dramatically shape patient outcomes and practitioner experience. Dr. Susan McMahon, a leading cosmetic dentist, sheds light on how NSK’s Z95L electric and Z2 air-driven handpieces are redefining what’s possible in restorative dentistry.
Smoother Preps, Better Crowns
Dr. McMahon, who has worked extensively with both electric and air-driven handpieces, makes a compelling case for why NSK’s models deliver superior performance. Traditional air-driven tools, she explains, often lose speed upon contact with the tooth — creating ragged, imprecise margins that can compromise crown fit. In contrast, NSK’s next-gen air-driven Z2s offer a powerful, consistent cut. With this product, “you don’t feather on and off the tooth,” she says. “You translate across the enamel, and it makes a beautiful margin.”
That smoothness is more than cosmetic. In today’s digital dental landscape, where most crowns are designed and manufactured from scans, clean, readable margins are essential for an accurate digital read. “The smoother the prep, the better the scan, the better the crown,” Dr. McMahon explains. With handpieces like the Z95L and Z2, dentists can prep faster and more effectively—and enjoy better long-term outcomes.
Tough Materials, No Problem
Modern materials like zirconia may have changed the game for durability—but they’ve also raised the bar for handpiece capability. Dr. McMahon points out that when it comes to removing zirconia crowns, older air-driven models often fall short. “You can be cutting forever and still not get through,” she says. But with NSK’s high-powered handpieces, she’s able to remove even the most stubborn restorations quickly and cleanly.
“You can cut a slot in the crown, pop in a crown spreader, and it just comes off,” she explains. “That’s not something you can do with a traditional handpiece.” The torque and precision of NSK’s design make it possible to cut through tough materials without overheating or dulling burs prematurely. In a busy practice, that kind of efficiency translates to better patient flow and less fatigue.
Designed for Dentists, Built for Comfort
Beyond precision, ergonomics play a vital role—especially in a physically demanding profession. “Dentistry is hard on your body,” says Dr. McMahon. “With these handpieces, I’ve cut my prep time in half.” Lighter weight, smaller head sizes, and smoother handling reduce strain and allow for better posture and control.
NSK’s Nano and Micro versions—designed with small hands in mind—also reflect a broader, welcome trend in dental technology: inclusivity. “I don’t think they were designed specifically for women,” she clarifies, “but they’re perfectly suited to my smaller hands.” With women now making up nearly 50% of the dental profession, it’s a relevant consideration.
Dr. McMahon’s verdict? “They’re workhorses. Nimble, powerful, low maintenance—and they make me a better dentist.” In her practice, where aesthetics and efficiency go hand in hand, NSK’s handpieces aren’t just tools—they’re essential collaborators in delivering precise and lasting results.
