Osstell Beacon Instructions

Updated June 24, 2020

These are the basic instructions, along with a video for the Osstell Beacon. The Osstell Beacon is an innovative and highly intuitive handheld device designed to assess dental implant stability using the Osstell ISQ and RFA technology.

How to Measure

  1. Activate the Osstell Beacon by picking it up. The instrument will start-up and after showing the battery status, the instrument will be ready for measurement in the BL (Buccal – Lingual) direction, which is prompted in the upper display as well as optimal angle towards the Smartpeg. osstell-beacon-1|640x468
  2. Place a barrier sleeve over the Osstell beacon instrument.
  3. Place the SmartPeg into the SmartPeg Mount. The SmartPeg is magnetic, and the SmartPeg Mount will hold the SmartPeg. See fig 2. Attach the SmartPeg to the implant or abutment by screwing the SmartPeg Mount using finger force of approximately 4-6 Ncm. Do not over-tighten, to avoid damaging the SmartPeg threads.


  1. Hold the instrument tip close (3-5mm) to the top of the SmartPeg without touching it. An audible sound indicates when measurement has started, and measured data will be shown in the upper display combined with a colored light indication below the tip. osstell-beacon-3|690x223
  2. Bring the instrument out of the mouth to clearly read the ISQ value and the colored indication. The measured ISQ values will be displayed in the upper display for a couple of seconds and then switch to be ready for measurement in mesial-distal direction.
  3. Repeat step 4 and the sequence starts over and the Osstell Beacon is ready for measurement in the BL (Buccal- Lingual) direction again.
  4. When all measurements are performed, remove the SmartPeg by using the SmartPeg Mount. The instrument is automatically turned off after 60 seconds of inactivity.

How to Interpret Beacon ISQ Results

Implant Stability An implant can have different stability in different directions. The stability of the implant is dependent of the surrounding bone configuration. To find the lowest stability (lowest ISQ value) it is recommended to measure from two different directions. The lowest stability is in most cases found in the buccal-lingual direction. The highest stability is in most cases found in the mesial-distal direction.

The ISQ Value ISQ measurements should be performed at implant placement and before the implant is loaded or the abutment is connected. After each measurement, the ISQ values are recorded and used as the baseline for the next measurement performed. A change in the ISQ value reflects a change in implant stability. In general, an increase in ISQ values from one measurement time to the next indicates a progression towards higher implant stability while a decrease in ISQ values indicates a loss in stability and, possibly, implant failure. A stable ISQ value would indicate no change in stability.
