Resonance frequency analysis (RFA) allows assess implant stability by measuring implant oscillation frequency
on the bone. RFA is an objective and non-invasive method for implant stability measurement, although scarce
evidence has been provided so far on its reliability.
Objectives: Assess the Osstell ISQ system's reliability (i.e., its measurement reproducibility and repeatability) by
means of the intraclass correlation coefficient (ICC) as statistical method.
Study Desing: Implants stability registers were completed by means of Osstell ISQ on 85 implants on 23 patients.
Six measurements were completed on each implant by means of two different SmartPegs (types I and II); that is,
three consecutive measurements with each transducer.
Results: Average ISQ was 72.40, 72.22 and 72.79, and 72.06, 72.59 and 72.82 in the first, second, and third measurements
with SmartPegs I and II, respectively. Equal values or differences below three ISQ points were observed
in 52.9% and 62.4% of the cases with SmartPegs I and II, respectively. The intraclass correlation coefficient was
0.97 for both SmartPegs, and repeatability and reproducibility also reached 0.97 for both SmartPegs.
Conclusions: The RFA system Osstell ISQ presents almost perfect repeatability and reproducibility after intraclass
correlation coefficient analysis. Osstell ISQ measurements are highly reliable regarding reproducibility.
Therefore, one measurement proves enough.
