“…Although the ISQ and PTV are widely used to noninvasively monitor implant stability, their associations with histomorphometric data during the healing process are still controversial and have not been definitively established [8, 21–23]. Therefore, the present study investigated whether implant stability parameters (ISQ and PTV values) correlated with peri-implant-bone healing (osseointegration, BIC values) at various healing time points.…”

“…The femoral condyles containing the implants were harvested using a diamond circular saw and subsequently fixed in 10% formalin solution for 7 days. Whole implant-bone samples were then processed without decalcification for ground sectioning according to the previous studies [8, 23]. In brief, the specimens were dehydrated in a graded series of ethanol (70% to 100%) over a period of 24 hours at 5°C and defatted in xylene under vacuum.…”

“…Although the Osstell and Periotest devices are widely used in daily dental practice, the reliability and validity of these two methods are still questioned [8, 13]. In addition, studies have also suggested that the individual measurement of implant stability using RFA or Periotest should be performed with caution and used in combination with other objective methods or clinical parameters [8, 13, 21].…”

The aim of this study was to monitor the changes of viscoelastic properties at bone-implant interface via resonance frequency analysis (RFA) and the Periotest device during the healing process in an experimental rabbit model. Twenty-four dental implants were inserted into the femoral condyles of rabbits. The animals were sacrificed immediately after implant installation or on day 14, 28, or 56 after surgery. Viscoelastic properties at bone-implant interface were evaluated by measuring the implant stability quotient (ISQ) using RFA and by measuring the Periotest values (PTVs) using the Periotest device. The bone/implant specimens were evaluated histopathologically and histomorphometrically to determine the degree of osseointegration (BIC%). The BIC% values at different time points were then compared with the corresponding ISQ values and PTVs. The mean ISQ value increased gradually and reached 81 ± 1.7 on day 56, whereas the mean PTV decreased over time, finally reaching −0.7 ± 0.5 on day 56. Significant correlations were found between ISQ and BIC% (r = 0.701, p < 0.001), PTV and BIC% (r = −0.637, p < 0.05), and ISQ and PTV (r = −0.68, p < 0.05). These results show that there is a positive correlation between implant stability parameters and peri-implant-bone healing, indicating that the RFA and Periotest are useful for measuring changes of viscoelastic properties at bone-implant interface and are reliable for indirectly predicting the degree of osseointegration.

“…Recent in vivo studies [30][31][32] investigated the correlation between resonance frequency analysis (ISQ value) and % BIC values in dental implants inserted in dog mandibles and human jaws. The authors concluded that there is a lack of correlation between these 2 values, and they could not identify the relationship between RFA and histomorphometrical data.…”

Objectives Functional tooth replacement and bone regeneration are parts of the daily practice in modern dentistry, but wellreproducible and relatively inexpensive experimental models are still missing. We aimed to develop a new small animal model to monitor osseointegration utilizing the combination of multiple evaluation protocols. Material and methods After cutting the tail between the C4 and C5 vertebrae in Wistar rats, costume made, parallel walled, nonthreaded implants were placed into the center of the tail parallel with its longitudinal axis using a surgical guide. Osseointegration of the titanium implants was followed between 4 and 16 weeks after surgery applying axial extraction force, and resonance frequency analysis as functional tests, and histomorphometry and micro-CT as structural evaluations. Results In functional tests, we observed that both methods are suitable for the detection of the time-dependent increase in osseointegration, but the sensitivity of the pull-out technique (an approximately five times increase with rather low standard error) was much higher than that of the resonance frequency analysis. In structural evaluations, changes in the detected bone implant contact values measured by histomorphometry (yielding 1.5 times increase, with low variations of data) were more reliable than micro-CT based evaluations to screen the developments of contact between bone and implant. Conclusion Our results provide evidence that the caudal vertebrae osseointegration model is useful for the preclinical evaluation of implant integration into the bone. Clinical relevance The combination of the biomechanical and structural tests offers a well-reproducible small animal system that can be suitable for studying the integration of various implant materials and surface treatments.

The comparison between implant stability quotient and bone‐implant contact revisited: an experiment in Beagle dog

Abstract: The lack of correlation between BIC and ISQ values suggests that ISQ as determined by RFA is not able to identify the relationship between RF and histomorphometrical data.
