Our Story

Osstell helps dentists and dental surgeons worldwide who want to provide safer, more effective and more successful implant treatment. This is our story.

How it all started

Osstell is the global leader in implant stability measurement and osseointegration progress monitoring. Osstell was formed in 1999 to commercialize an invention using Resonance Frequency Analysis (RFA) to determine the clinical status of a dental implant. More than 1 400 scientific publications confirm the benefits of the technology, its clinical value, and the use of the ISQ scale for dentists in their daily practices. Osstell is headquartered in Gothenburg, Sweden – the birthplace of dental implants. Since 2018, Osstell is part of the W&H group, one of the world’s leading manufacturers of dental precision instruments and devices.





Our method eliminates chance. When measuring the implant stability, you will get an objective value, making the implant treatment more predictable – even for patients with risk factors.

Reduced treatment time

Immediate loading is becoming more and more common. Patients want results fast. With Osstell®, you only wait as long as needed.

Proven method

Backed by more than 1400 scientific studies, our method is based on RFA to determine whether or not an implant is stable enough. The result is presented as an ISQ value of 1-100. The higher the ISQ, the more stable the implant.

As a surgical specialist, I work closely with my restorative colleagues. When immediate and early loading treatment is selected, I need certainty in communicating implant stability. Osstell ISQ gives me a “number” I can provide as a tangible measurement of stability. If changes in loading protocols are appropriate, I can provide a numerical value that makes sense and keeps all members of the team on the same page. I value this technology and feel it has only just begun to demonstrate all of its applications in clinical practice.

The ability to better diagnose implant stability and integration by resonance frequency analysis has provided improved confidence of the treating team as well as better patient management. It has also distinguished Misch Implant Dentistry as a practice that utilizes the latest technology available to provide superior care
