The HuFriedyGroup line of Harmony Ergonomic Scalers and Curettes was designed was TrueFit technology, which is a sensor-based testing system that measures pinch force in the finger and pressure applied to the tooth when scaling.
With more than 2.8 million data points recorded, the company said, its researchers used TrueFit to develop a scaler handle with optimal proportions and ideal width that provides a secure and nimble grasp.
“We set out with the goal of developing a new scaler that would provide scientifically proven ergonomic benefit for clinicians, improving their experience and that of the patient as well,” said Stacie Barth, vice president of the HuFriedyGroup Global Strategic Business Unit.
“Our rigorous, data-supported design process is a novel approach for the industry, and the results speak for themselves,” Barth said. “More than ever, clinicians and dental hygienists need to feel comfortable with their instruments, and the new Harmony Scaler is designed precisely to improve their daily working experience.”
HuFriedyGroup said it relied on a broad, globe-spanning group of hygienists to participate in testing and development as part of an iterative design process. The company also worked with a third-party analytics firm to review and analyze the resulting 2,878,320 data points.
The handle reduces pinch force by up to 65% compared to other leading scaler designs, the company said, reducing the amount of pressure that users need to apply and alleviating hand fatigue and injury risk due to repetitive motion.
With up to 37% less pressure against the tooth surface during scaling compared to other leading scaler handle designs, HuFriedyGroup said, the Harmony Scalers and Curettes can increase patient comfort and reduce clinician fatigue.
Furthermore, the Harmony line features EverEdge 2.0 Working Ends, which are 72% sharper than the next leading competitor, which also contributes to a more comfortable experience for both clinician and patient, the company said.
With a recessed double-helix texture, the durable metal handle is designed for optimal tactile sensitivity and to reduce tactile fatigue, HuFriedyGroup said. The comfortable silicone grip, which has been extended by 30%, provides a secure and nimble grasp with a geometric pattern specifically designed for a stable grip in any direction, according to the company.
Clinicians can comfortably maneuver and roll the scaler due to the round shape of the handle and the smooth transition to the functional shank, HuFriedyGroup said.
With 30 unique working end options, including Sickles, Universals, and Graceys, the Harmony Scaler is immediately available for purchase in the United States from authorized HuFriedyGroup representatives or dental distributors.
