Efficacy of Resonance Frequency Analysis in the Diagnosis of Compromised Bone-Implant Interface

Abstract

RFA is not a reliable method in the assessment of the initial contact loss at bone-implant interface.

Effects of different loading protocols on the secondary stability and peri‐implant bone density of the single implants in the posterior maxilla

“…In recent studies, it was reported that RFA was a reliable tool for assessment of implant stability and ISQ value significantly correlated with other implant stability parameters such as insertion torque value, bone density, actual micro‐motion value, and fractal analysis . However, controversial results were also reported about the reliability of ISQ for the assessment of implant stability . Some factors can affect implant stability and ISQ recordings such as bone quality, shape of the implant, thread design, surface treatment, surgical technique and the experience of the surgeon .…”

“…35,36 However, controversial results were also reported about the reliability of ISQ for the assessment of implant stability. 37,38 Some factors can affect implant stability and ISQ recordings such as bone quality, shape of the implant, thread design, surface treatment, surgical technique and the experience of the surgeon. 39 In this study, all of the factors that have the possibility to affect ISQ recordings were standardized by using same implant, same region (maxillary posterior area),1 surgeon, and standard surgical technique.…”

Novel Implant Design Improves Implant Survival in Multirooted Extraction Sites: A Preclinical Pilot Study

“…Although RFA measurements that were previously published were performed on tapered or conical implants, this is the first attempt to use the resonance frequency analysis instrument in anatomically shaped tripod implants. Inconsistent results of RFA and BIC measurements were previously reported in clinical and preclinical studies 26,27 . In a recently published study, Manresa et al 28 tested the association between BIC and RFA measurements.…”

Comparison of Measurements of Implant Stability by Two Different Radio Frequency Analysis Systems: An In Vitro Study

“…In an animal study, Abrahamsson et al 31 could not find a relationship between the histological parameters of osseointegration and ISQ values and stated that the value of RFA to predict implant stability has to be questioned. An in vitro study by Çavusloğlu et al 32 evaluated the efficacy of RFA and the results demonstrated that RFA was not a reliable method for the assessment of the initial contact loss around the implant. On the other hand, Cho et al 33 defined the RFA method was as an objective, reliable, and useful method for clinical practice.…”
