12) How to Measure on an Abutment
When a measurement is made on an abutment or on an implant with a
“built-in” abutment, the ISQ value will be lower compared to a measure-
ment made on the implant. This is due to the difference in height above
bone level. To find out the ISQ difference to the measurement performed
at implant level, a measurement should be taken on the implant before
the abutment is attached and then a second measurement on the
abutment.
13) Interpret the Result
Implant Stability
An implant can have different stability in different directions. The
stability of the implant is dependent of the surrounding bone config-
uration. There is often a direction where the stability is lowest, and a
direction where the stability is highest and these two directions are most
often perpendicular to each other.
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
Assuming there is access to the implant, 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
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 meas-
urement 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. ISQ values have not been correlated with other methodes of
mobility measurements.
Note! The final implant treatment decisions are the responsibility of the
clinician.
14) Data Connection to Osstell Connect
The Osstell Connect is an online service for data transfer, storage, display
and overview of your data.You can have your Osstell Beacon online
connected to Osstell Connect by the Osstell Key.
Before you can start using connection to Osstell Connect you have to
register your Osstell Beacon. The serial number can be found on the
back of the instrument. For registration assistance, please visit:
osstell.com/get-started-beacon-us.
15) Cleaning and Maintenance
After each use, follow the below cleaning and desinfection procedures.
Note! Do not autoclave the Osstell Beacon instrument.
Routinely check the surface of the instrument tip and overall surface for
possible cracks and residuals.
