Hand relief down to a science

Designed around the way clinicians work

TrueFit™ Technology is an advanced sensor-based technology system which measured 2,878,320 data points for pinch force in the finger and pressure applied to the tooth when scaling.4

Up to 65%

reduction in pinch force4

This may alleviate hand fatigue and injury risk due to repetitive motions.5–8

37%

less pressure on the tooth4

Harmony™ Ergonomic Scalers and Curettes may increase patient comfort, while reducing clinician fatigue because it requires less pressure to the tooth when scaling.

Every detail works together

Comfortably manoeuvre and roll the scaler due to the round shape of the handle and the smooth transition to the functional shank.

Features and benefits

Comfort, control and tactile confidence

A balanced design combines the working end, grip and handle to support precise hand scaling.

01

Secure and nimble grasp

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

02

Balanced in the hand

The perfectly balanced handle is similar in weight to the EverEdge™ 2.0 #9 Metal Handle.

03

Tactile sensitivity

The durable metal handle features a recessed double-helix texture designed for optimal tactile sensitivity and to reduce tactile fatigue.

04

EverEdge™ 2.0 working ends

EverEdge™ 2.0 working ends, which are 72% sharper than the next leading competitor, allow clinicians to efficiently remove calculus.2

TrueFit™ Technology

Evidence-led ergonomic development

HuFriedyGroup pioneered TrueFit™ Technology to address the need for scientific evidence in ergonomics.

01

Fact versus fiction

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.

02

Global clinician input

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

03

Design. Test. Refine.

TrueFit™ Technology measured touch sensitivity and pressure at 40 readings per second, enabling an iterative development process that refined the Harmony™ design.
