K-ERGOgrip™ Installation

Lab Handpieces

Quality, Torque, and Special Ergonomics for Comfortable Working

Potential performance statistics are one thing, but putting this potential to best use is something else entirely. The ability of the   KaVo K-ERGOgripTM to offer even more is in evidence in its daily application. You've simply got to hand it to the concept of this innovative laboratory drive.

ERGOgrip - KaVo Quality, Performance, and Ergonomics

The art of Dental Technology is Complex

Despite the intricate nature of the work itself, the long periods of maximum concentration typical of complex laboratory tasks often require a lot of stamina. The angle one's wrist needs to be set at in order to work with conventional laboratory drives or handpieces can place dental technicians under significant strain.

Developed and designed in accordance with anatomical needs, KaVo’s new K-ERGOgrip laboratory drive is a perfect and logical solution to this problem, as well as weighing even less. The new KaVo K-ERGOgrip is also significantly more compact, at just 140 mm in length.

Continuous Power At Its Very Best

The groundbreaking grip ergonomics of KaVo’s K-ERGOgrip facilitate prolonged fatigue free working. The drive unit’s resilient mechanics have also been designed with optimum performance in mind. Vibration-free and with apparent ease, the collectorless DC motor makes its hightorque power available in a speed range from 1000 to 50,000 rpm.

Precision and Relaxation = K-ERGOgrip

The KaVo “relax bonus”: elongated angle for optimum ergonomics at work.

Absolute perfection at your fingertips. Working in partnership with Germany’s Fraunhofer research institute, KaVo’s handpiece, whose design reflects the very best in ergonomics, is an absolute masterpiece. As part of the process of creating a handpiece for the KaVo K-ERGOgrip laboratory drive which would provide the ideal response to working needs, video analyses and practical tests involving volunteers were carried out.

The significantly reduced bend of the wrist supports a much more relaxed grip, optimising working conditions and enabling technicians to concentrate fully on the task at hand. Now, even tedious and complex tasks requiring maximum precision can be mastered “at the flick of a wrist”.

K-ERGOgrip – Recipient of the IF Award

The K-ERGOgrip handpiece is a recipient of the IF Award. The award was based mainly on the ergonomics that was the main focus in the development of this handpiece. "The resulting shape of the grip ensures fatigue-free working.

Its design length is much reduced as compared to other commercial handpieces which affords a better distribution of the weight in the user's hand. In order to be able to adapt the handpiece to different anatomical situations (large/small hands), the device is provided with a second gripping sleeve that is easy to exchange."

Select Between Table, Knee, or Foot control

The functions of the KaVo K-ERGOgrip can be controlled either directly on the central table‑top unit or via a connected knee or foot control.

  • 4 Preselectable programs (material-dependent)
  • Settable torque
  • Four-colour display (program-dependent)

Individual users can create performance profiles to meet their specific requirements by presetting and saving torque and speed values in four programs. The maximum values for speed and torque can be set separately and independently of these programs.
