Abstract
Aim:To compare and evaluate the implant stability quotient (ISQ) measurements by two different radio frequency analysis (RFA) machines, Osstell Mentor and PenguinRFA.Materials and Methods:Twenty bone-level implants (3.7 × 10 mm2) were placed on a bovine bone in this in vitro study. The ISQ measurements were performed with the PenguinRFAand Osstell Mentor machines using the multipeg of the Penguin system. The measurements were repeated three times for each direction and an average ISQ value was calculated. The results were averaged (mean ± SD) and the intraclass correlation coefficient (ICC) was calculated to assess the relationship between the measurements.Result:The mean ISQ values for the Osstell and Penguin machines were 77.60 + 2.11 and 78.05 + 2.04, respectively. The ICC was 0.958. The ISQ values obtained from the Osstell and Penguin machines were significantly compatible ( P < .05).Conclusion:Both of the RFA devices provided similar and reliable ISQ measurements.
