Clinical evaluation of osseointegration using resonance frequency analysis [PDF]

open access: yesThe Journal of Indian Prosthodontic Society, 2015
The stability of the implant at the time of placement and during the development of the osseointegration process are the two major issues governing the implant survival.

Resonance frequency analysis of implants placed in condensed bone [PDF]

open access: yesClinical Oral Implants Research, 2021
AbstractObjectivesResonance frequency analysis (RFA) is used to monitor implant stability. Its output, the Implant Stability Quotient (ISQ), supposedly correlates with insertion torque, a common measurement of primary stability. However, the reliability of RFA in condensed bone remains unclear.Material and methodsIn this human cadaver study in ...

Resonance frequency analysis

open access: yesIndian Journal of Dental Research, 2011
Initial stability at the placement and development of osseointegration are two major issues for implant survival. Implant stability is a mechanical phenomenon which is related to the local bone quality and quantity, type of implant, and placement ...

Comparison of Resonance Frequency Analysis and of Quantitative Ultrasound to Assess Dental Implant Osseointegration [PDF]

open access: yesSensors, 2018
Dental implants are widely used in the clinic. However, there remain risks of failure, which depend on the implant stability. The aim of this paper is to compare two methods based on resonance frequency analysis (RFA) and on quantitative ultrasound (QUS)

Design and Optimization of the Resonator in a Resonant Accelerometer Based on Mode and Frequency Analysis [PDF]

open access: yesMicromachines, 2021
This study aims to develop methods to design and optimize the resonator in a resonant accelerometer based on mode and frequency analysis. First, according to the working principle of a resonant accelerometer, the resonator is divided into three parts: beam I, beam II, and beam III.

Evaluation of variation in implant stability quotient at different time intervals after immediate loading in the posterior mandible using penguin resonance frequency analysis system

open access: yesIndian Journal of Dental Sciences, 2021
Purpose: The aim of this in vivo study is to compare the variation in implant stability quotient (ISQ) values of implants using resonance frequency analysis (RFA) to access the immediately loaded (within 24 h) implants at different time intervals using ...

Research on a risk evaluation and suppression method for high-frequency resonance of flexible low-frequency transmission

open access: yesZhejiang dianli, 2022
Due to the long delay of their control chains, voltage source converters (VSCs) in the high frequency band tend to show negative damping, which may give rise to high-frequency resonance when VSCs are connected to power systems.

Resonant frequency analysis of dental implants [PDF]

open access: yesMedical Engineering & Physics, 2019
Dental implant stability influences the decision on the determination of the duration between implant insertion and loading, This work investigates the resonant frequency analysis by means of a numerical model. The investigation is done numerically through the determination of the eigenfrequencies and performing a steady state response analyses using a
