Resonance frequency analysis with two different devices after conventional implant placement with ridge preservation: A prospective pilot cohort study

Abstract

Background: Primary and secondary implant stability is of high importance for survival and success of dental implants in the short and long term. Measurements of implant stability during healing provide the opportunity to monitor the course of the osseointegration process.Purpose: To compare implant stability quotient (ISQ) by resonance frequency analysis (RFA), recorded with two different devices after implant placement.Materials and methods: Patients with the need of single tooth extraction in posterior sites of the maxilla and the mandible were treated in a surgical center. All patients received additional augmentation with a bovine bone substitute and platelet-rich fibrin (PRF) after atraumatic tooth extraction. After a healing period of 10 weeks, 28 self-tapping titanium-implants were placed. Implant stability was recorded with two different devices (Osstell and Penguin) at the time of implant insertion (T0), 10 days later (T1), and after 7 (T2), or 17 weeks (T3).Results: No implant was lost, and no postoperative complication occurred during follow-up. Patient cohort comprised 9 female (32.1%) and 19 male patients (67.9%), with a mean age of 52.8 years, 64.3 years, respectively. Mean overall insertion torque was 43.6 Ncm at implant placement with no significant difference between implant location, age, or gender. No patient dropped out. During observation period, a significant increase in mean ISQ was recorded with both devices. Significant positive correlations between insertion torque and ISQ were recorded with both devices at T0, T2, and T3. No significant differences were observed in ISQ-values between both devices, and measuring directions at any point of measurement.Conclusions: Within the limitations of this cohort study, both devices were suitable for RFA-measurement and revealed comparable results. Due to the cordless design, handling of the Penquin device was more comfortable. Reusability of the Penguin MultiPeg-transducers may offer an additional benefit with regard on ecological aspects.

A Comparative Study of Two Resonance Frequency Analysis Instruments

“…It is important to note that rotational and lateral PIS are different concepts, but both are affected by the same conditions and determine the success of implant osseointegration. This is also reflected in recent studies by Elio Oliveros et al [23] and Brouwer et al [26] Additionally, Gomez-Polo et al [27] indicate that higher IT values are associated with higher primary ISQ.…”

Effect of implant diameter and cantilever length on the marginal bone height changes and stability of implants supporting screw retained prostheses: A randomized double blinded control trial

“…Merheb et al 26 and Su et al 27 agreed that resonance frequency analysis devices are capable of determining any alterations in the bone configuration and bone resorption around implants. The resonance frequency analysis ISQ value reflects the bone height levels of a given implant and the stiffness of the implant in the adjacent bone, 28 29 and is considered a relevant tool to predict osseointegration. 29 30 31 …”

Correlation Between Implant Stability Quotient and Percussion Sound Frequency

“…When the magnetic resonance frequency probe activates the peg, it vibrates and produces an electric volt that is recorded by the magnetic resonance frequency analyzer. At present, Osstell ISQ (Osstell AB, Gothenburg, Sweden), which is a magnetic resonance frequency analysis device that uses a SmartPeg transducer, is commonly used because of its simplicity of use and repeatability, as well as its accuracy and reliability (Brouwers et al 2021 ; Bural, Dayan, and Geçkili 2020 ). When evaluating implant stability, the related SmartPeg transducer and Osstell ISQ detect the frequency of vibrations and convert it into an implant ISQ value.…”
