The measured ISQ values will be displayed in the upper display
for a couple of seconds and then switch to indicate ready for
measurement in mesial-distal direction.
See fig 3 and 4.
Note!
Do not bring the instrument tip to the SmartPeg until the
upper display has switched to next direction.
5. Do not measure from above. See fig 5 .
6. Repeat step 4 and the sequence starts over and the Osstell Beacon
is ready for measurement in the BL (Buccal- Lingual) direction
again.
See fig 3
.
7. When all measurements are performed, remove the SmartPeg by
using the SmartPeg Mount.
8. The instrument is automatically turned off after 60 seconds of no
motion.
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 measurement 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
configuration. 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 stabil-
ity 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 load-
ed 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
