Today the focus is on ergonomics – without losing sight of efficiency. The new LM-ErgoSense hand instrument, meets both of these requirements and is truly a unique combination of evidence based ergonomic design and integrated new technology.
LM-ErgoSense is the outcome of intense research and product development in close cooperation with dental clinicians and occupational health professionals. By placing electrodes on different parts of the hand, arm and body the muscular activity and strain was measured on clinicians working in a phantom laboratory setting. An ergonomic, high quality hand instrument naturally feels good in the hand. Even genuinely sensational as the new, smart LM-ErgoSense has been described. By combining a high friction silicone surface that reduces the muscle pinch force needed in clinical work and scientifically designed handle, the most ergonomic hand instrument is created.
“Feels great in the hand”
The value of a truly ergonomic instrument grip can never be emphasized enough as revealed in several scientific studies. A hand instrument with thick silicone handle has been found to be more usable, cause lower perceived strain and to be more productive than those with thinner handles. LM-ErgoSense was rated as the best in ten out of fourteen specified usability features compared with the other tested instruments in a dental scaling simulation. It was also ranked as the best instrument.
LM-Dental has developed the idea of an ergonomic instrument even further. An advanced autoclavable RFID chip can now be integrated into new LM-ErgoSense instrument handles enabling complete and reliable traceability of the instrument. The scanned and documented information improve patient safety, material handling and increase cost efficiency. This makes LM-ErgoSense hand instrument a truly unique combination of ergonomic design and new technology.
