About Osstell

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

About Osstell

  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. Osstell’s proprietary and patented technology helps its customers, dentists around the world, to make dental implant treatments safer, and to increase patient confidence and comfort, by measuring the stability of implants objectively and non-invasively using the ISQ scale (Implant Stability Quotient). More than 1 000 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.
