“…The current results are in accordance with those of Al-Jetaily et al (22) who investigated the sensitivity and reliability of the Osstell system compared to the Periotest system in implant bone simulated conditions (vitro study). The encountered results also agree with Gul Buyukguclu et al (23) who reported highly reliable of the Osstell system. In contrast to presented results, Bilhan et al (24) who reported that there was no significance when Periotest was compared with ISQ values observed for the same implants.…”

Objective: Objective measurement of implant stability through various techniques could assist the clinician in an optimal treatment plan, support decisions regarding implant loading, provides better case documentation, support good communication and increase trust. Therefore, it is very important to detect the accuracy of the most popular noninvasive devices (Periotest, Osstell) that are used in measuring implant stability for evaluating the long-term success of implant. The aim of this study was to evaluate the Osstell and Periotest devices' accuracy in measuring the immediate dental implants stability. Subjects & Methods: The stability was measured for 32 immediate implants (16 males, 16 females with age range from 25 to 45 years old) by the two devices at the time of implant placement, 6 and 12 months after surgery for each observer. Measurements were performed on four groups according to the site of placement of the immediate implants and classified as anterior area of the maxilla (group A), posterior area of the maxilla (group B), anterior area of the mandible (group C) and posterior area of the mandible (group D). Results: Intra class Correlation Coefficient indicated less reproducibility by the Periotest device compared to Osstell device. This result was confirmed by using the Quantile-Quantile Plot and the distribution of Osstell values was almost linear to the normal distribution in the 1 st and 2 nd measurements. The Periotest values differed from the normal distribution. Conclusion: Both the Osstell (ISQs) and Periotest (PTVs) systems may indicate reliable assessments of implant stability. The Osstell system may exhibit better reliability compared to Periotest in measuring the implant stability at time of placement and during healing, up to 12 months.

“…The measurements were taken immediately after implant placement in the vestibular and lingual positions perpendicular to SmartPeg rods (SmartPeg; Osstell AB, Gothenburg, Sweden), placed on the implants. The 22 implants' ISQ (Implant Stability Quotient) was measured at five stages: at baseline, and at 2, 6, 12, and 24 months after implant placement [28,29]. Sutures were removed two weeks after implant placement.…”

In many clinical situations, rehabilitation with implants in the posterior maxillary region is complicated by limited bone availability. In this context, the use of 4 mm long implants (known as extra-short implants) may be used thanks to the concept of osseointegration enhancement. It has been demonstrated that short implants offer an alternative to the regeneration procedures involved in placing longer implants in areas where bone height is compromised. This prospective pilot study tested a treatment protocol in which 11 extra-short (4 mm) implants were splinted to 11 mesially placed longer (8 mm) implants in the posterior maxillary regions of partially edentulous patients, without using supplementary bone regeneration procedures. Eleven patients were included in this single cohort study. The clinical performance of the extra-short implants was assessed during a two-year follow-up period, obtaining a 100% survival rate and mean bone loss of 0.3 mm. Implant stability measured by resonance frequency analysis (RFA) at the time of placement was 54.9 ± 4.9, increasing to 77.0 ± 2.6 at 24 months. The study demonstrated the gradual consolidation of osseointegration in bone of less-than-ideal quality in the posterior maxillary region. The results obtained show that a partially edentulous maxilla with reduced bone height may be rehabilitated by using an extra-short implant splinted to a mesial implant of 8mm length or longer. Despite the small sample size, this pilot study observed that extra-short implants achieved adequate bone stability and clinical performance after a 24-month follow-up.

“…Therefore, the RFA device relies on the physical phenomenon of resonance to determine the natural frequency of vibration of each implant and thus provide the clinician an implant stability quotient value (ISQ) on a scale of 0 to 100 (30). Currently, there are several devices on the market that use RFA as a method of measuring implant stability, such as the Osstell IDX (Osstell, Gothembourg, Sweden) and the Penguin RFA (Integration Diagnostics Sweden AB, Gothenburg, Sweden) (31,32). The objective of the present in vitro experimental study was to determine the influence of the presence of cortical bone and how the design of the implant impacts implant stability, as well as to compare the results of the measurements obtained using two different RFA devices.…”

Influence of cortical bone and implant design in the primary stability of dental implants measured by two different devices of resonance frequency analysis: An in vitro study

et al. 2020

Background: This study aimed to evaluate the effect of the implant design and the presence of cortical bone in the primary stability, as well as analyze the differences between the stability measurements obtained by two different resonance frequency analysis (RFA) devices. Material and Methods: A total of 80 Klockner implants of two different models [40 Essential Cone implants (group A) and 40 Vega implants (group B)] were used. The implants were placed in two polyurethane blocks that simulated the mechanical properties of the maxillary bone. One block featured a layer of cortical bone that was absent from the other block. The primary stability of all implants was measured by insertion torque and RFA using two different devices: Penguin RFA and Osstell IDX. Results: Primary stability was superior in the cortical bone in both torque and RFA. In the block containing cortical bone, group A implants obtained a greater insertion torque than did group B. The insertion torque was lesser in the bone lacking cortex. Regarding the ISQ of the implants, group A presented higher values in the block with cortical bone, but the values were lower in the block without cortical bone. There were no significant differences between the values obtained from the Osstell IDX and Penguin RFA. Conclusions: The presence of cortical bone positively influences the primary stability of dental implants. The design of the implant also has a statistically significant influence on implant primary stability, although the impact depends on whether there is coronal cerclage or not. There were no statistically significant differences in the implant stability measurements obtained by two different devices.

Reliability of the Osstell Implant Stability Quotient and Penguin Resonance Frequency Analysis to Evaluate Implant Stability

Abstract: Osstell ISQ and Penguin RFA are reliable only when the implants are embedded in stiff materials. Osstell ISQ is more reliable than Penguin RFA.
