It is a stability measuring device that uses tapping method, which measures the time of the Tapping Rod of the device contacting the implant
for dentistry and dental implantology or oral cavity, or abutment, to
measure the stability of the placed implant. The result of the measure-
ment is displayed in iST scale (implant Stability Test), which is the numer-
ical representation of the Implant Stability Test (iST) value, and higher
scale represents greater implant stability or lower implant mobility.
Characteristics
Convenient usage due to small and light design
Easy to use due to simple controlling method
Fast measuring time less than 3 seconds
Safe measurement due to slight tapping technique and auto safety
system (tapping stops after tapping twice when Osseointegration is
unstable, otherwise taps up to 6 times.)
Available to check possibility of implant failure at in earlier stages
This model is much simpler to use than the NSK model. With the NSK model, you need to install a probe on the implant first. With this model, you can see the ISQ value on the display screen by gently tapping the implant. From the numerical value  Determine the stability of the implant.
