HARMONY™ ERGONOMIC SCALERS AND CURETTES

Designed with Truefit™ Technology

DETAILS THAT MAKE A DIFFERENCE

Fits for you with over 2.8 Million Data Points

Knowing nearly 70% of RDHs experience hand, wrist, and/or arm pain,1 HuFriedyGroup proactively developed an innovative and truly ergonomic hand scaling solution. Building off the success of EverEdge™ 2.0 instruments, the NEW Harmony™ Ergonomic Scalers and Curettes designed with TrueFit™ Technology are the latest addition to the best-in-class hand instrument portfolio.

FEATURES & BENEFITS:

REDUCES PINCH FORCE UP TO 65%4
This may alleviate hand fatigue and injury risk due to repetitive motions.5, 6, 7, 8

REDUCES PRESSURE ON TOOTH BY 37%4
Harmony™ Ergonomic Scalers and Curettes may increase patient comfort, while reducing clinician fatigue because it requires less pressure to the tooth when scaling.

SHARP MATTERS – 72% SHARPER
EverEdge™ 2.0 working ends, which are 72% sharper than the next leading competitor, allow clinicians to efficiently remove calculus.2 Sharp scalers require less pressure to do the same amount of work, creating a more comfortable experience for you and your patients.

SECURE AND NIMBLE GRASP
The silicone grip has been extended by 30%which can provide a secure and nimble grasp while using the instrument.3 The geometric pattern is specifically designed to maximize grip in all directions.

CONFIDENCE IN YOUR HAND
The durable metal handle, which features a recessed double-helix texture, is designed for optimal tactile sensitivity and to reduce tactile fatigue.

NOT TOO HEAVY OR TOO LIGHT
The Harmony™ Ergonomic Scaler and Currette’s perfectly balanced handle is similar in weight to our best in class EverEdge™ 2.0 #9 Metal Handle.

2.8 MILLION DATA POINTS

Comfortably maneuver and roll the scaler due to the round shape of the handle and the smooth transition to the functional shank. With over 2.8 million data points measured, this handle was designed to easily adapt to your individual grasp.

TRUEFIT™ TECHNOLOGY

TrueFit™ Technology is an advanced sensorbased technology system which has measured 2,878,320 data points for pinch force in the finger and pressure applied to the tooth when scaling.4 HuFriedyGroup pioneered TrueFit Technology to address the need for scientific evidence in ergonomics.

 

Fact Versus Fiction

Harmony

HuFriedyGroup sought to distinguish factual parameters, such as pinch force and pressure on the tooth, that could be used to develop an ergonomic handle design for your instruments.

 

Global Influence

HarmonyHygienists spanning countries and continents around the world, with no bias to their brand or product preference, participated in testing the different designs.

Advanced Technology

In building the TrueFit™ Technology system, we partnered with global leaders in technology and development to design an advanced platform. HuFriedyGroup developed a system capable of measuring touch sensitivity and pressure at 40 readings per second. The system was adaptable to all users and designs, without interfering with the practitioners or instruments being tested. This enabled our engineers to create an iterative development process that refined the Harmony™ Ergonomic Scaler and Currette design for optimal performance.

DESIGN...TEST...REVISE

A development process, similar to software engineering, was adopted for the Harmony™ Ergonomic Scalers and Currettes. A gamut of handles was used as the starting point for our research. These different handle designs helped establish comparison points for iterative development. New design concepts were created, then tested, and features that showed the strongest performance were progressed whereas elements that did not perform well were removed. This step-by-step approach of design, test, and revise allowed us to make rapid progression on key factors like reduction of pinch force and reduced pressure on the tooth.

HAND RELIEF DOWN TO A SCIENCE

To keep a scientific perspective and accurate representation of the data collected, HuFriedyGroup worked with a world renowned 3rd party analytics firm to review and analyze the 2,878,320 data points.4 They applied a scientific level of analyses to the data gathered with TrueFit™ Technology and assessed it without bias to determine key findings and statistical relevance among the collected data samples.
