“…Negative PTV values indicate the implant's stability for potential immediate load and positive higher values indicate implant micromovement and potential contraindication for implant loading [48]. The resonance frequency analysis has demonstrated reliability in in vitro studies, [49] and values over >60 ISQ allow immediate loading. However, variations in the tightening force of the transducer on the implant can increase the variability of the stability measurements [50].…”

The goal of this study was to evaluate the effects of two implant bed preparation techniques on the implant primary stability (IPS) and the bone density of the implant site. We completed 40 implant bed osteotomies in pig ribs using two techniques: osseodensification (OD) plus under-drilling (UD) with universal osseodensification drills (Test A), and under-drilling alone with drills of the same implant system (Test B). Implants with a 4.1 mm diameter and 10 mm length were inserted, and the IPS was evaluated with three methods: (insertion torque (IT), periotest (PTV), and resonance frequency analysis (RFA). The bone density was evaluated using micro-computed tomography. ANOVA and Tukey’s post-hoc test were used for comparison of the IPS values, and Kruskal–Wallis was used to evaluate the bone density. Statistical significance was set at p < 0.05. The tested B technique (UD) achieved a higher IPS compared to the Test A technique (OD + UD) for all the evaluation methods (p < 0.05). Bone density was higher at the apical and middle region in Test A compared to Test B and control sites (p < 0.05). We concluded that although the bone density increased with the hybrid OD technique with universal drills, implant beds prepared with UD using drills with geometry similar to that of the implant are more efficient at increasing IPS values.

“…The transducer peg for each device (smartpeg for Osstell and MegaISQ and multipeg for Penguin) was inserted on each implant according to the manufacturer's instructions, and two measurements were recorded parallel and perpendicular (lingual) to the longitudinal axis of the peg. Due to the reliability provided by previous studies [12][13][14][15], Penguin ® was used as the control.…”

“…These analyses have focused on two devices: Osstell ® (W&H, Göteborg, Sweden) and Penguin ® (Integration Diagnostics Sweden AB, Göteborg, Sweden) [12][13][14]. For instance, Buyukguclu et al [12] reported better reliability for Osstell ® , while Romanos et al [13] reported that both devices were sensitive and reliable. Bural et al reported excellent reliability for Penguin ® , but they did not report the reliability of Osstell ® [14].…”

Reliability and Agreement of Three Devices for Measuring Implant Stability Quotient in the Animal Ex Vivo Model

et al. 2021

Resonance frequency analysis (RFA) is the most extended method for measuring implant stability. The implant stability quotient (ISQ) is the measure obtained by different RFA devices; however, inter- and intra-rater reliability and agreement of these instruments remain unknown. Thirty implants were placed in three different pig mandibles. ISQ was measured parallel and perpendicular (lingual) to the peg axis with Osstell® Beacon, Penguin® and MegaISQ® by two different investigators and furthermore, one performed a test-retest. Intraclass correlation coefficient was calculated to assess the intra- and inter-rater reliability. Pearson correlation coefficient was used to assess the agreement. Intraclass correlation coefficients ranged from 0.20 to 0.65 for the Osstell® Beacon; 0.57 to 0.86 for the Penguin®; and −0.01 to 0.60 for the MegaISQ®. The highest ISQ values were obtained using Penguin® (66.3) in a parallel measurement; the lowest, using the MegaISQ® (60.1) in a parallel measurement. The highest correlation values with the other devices were obtained by MegaISQ® in a parallel measurement. Osstell® Beacon and MegaISQ® showed lower reliability than Penguin®. Osstell® had good agreement for measuring ISQ both in parallel and perpendicular, and MegaISQ® had the best agreement for measuring ISQ in parallel.

“…After being excited, it vibrates and emits an electric voltage to the probe that will be transformed into an ISQ value. ISQ values seems to be influenced by several factors such as bone implant contact (BIC), which in turn is influenced by implant morphology and surface properties, among others; implant design, length, and diameter [ 4 ]; force at which the transducers are screwed (4–5 N/cm are recommended) [ 9 , 10 , 11 ]; interposed soft tissue between the SmartPeg and the implant [ 4 ]; bone quality [ 12 ]; probe position and effective implant length (EIL), which is defined as the distance from the transducer to the marginal bone (the greater the distance, the lower ISQ values are obtained) [ 4 , 10 , 13 , 14 ].…”

Resonance frequency analysis (RFA) requires abutment disconnection to monitor implant stability. To overcome this limitation, an experimental transepithelial abutment was designed to allow a SmartPeg to be screwed onto it, in order to determine the prototype abutments repeatability and reproducibility using Osstell ISQ and to assess whether implant length and diameter have an influence on the reliability of these measurements. RFA was conducted with a SmartPeg screwed directly into the implant and onto experimental abutments of different heights of 2, 3.5 and 5 mm. A total of 32 patients (116 implants) were tested. RFA measurements were taken twice for each group from mesial, distal, buccal and palatal/lingual surfaces. Mean values and SD were calculated and Intraclass Correlation Coefficients (ICC) (p < 0.05, IC 95%). The implant stability quotient (ISQ) mean values were 72.581 measured directly to implant and 72.899 (2 mm), 72.391 (3.5 mm) and 71.458 (5 mm) measured from the prototypes. ICC between measurements made directly to implant and through 2-, 3.5- and 5-mm abutments were 0.908, 0.919 and 0.939, respectively. RFA values registered through the experimental transepithelial abutments achieved a high reliability. Neither the implant length nor the diameter had any influence on the measurements’ reliability.
