Implant stability measurements using resonance frequency analysis: biological and biomechanical aspects and clinical implications

Relationship between implant stability measurements obtained by insertion torque and resonance frequency analysis: A systematic review

“…27,38,39 In the present study, there was no evidence that these 2 techniques statistically correlated, in agreement with the results shown in another clinically conducted study. 32 However, a study conducted with an edentulous mandible of a cadaver found a correlation between them.…”

Stability of dental implants after irradiation with an 830-nm low-level laser: a double-blind randomized clinical study

“…The outcome of an implant stability analysis is highly dependent on the type of test used and the direction and type of the applied force [48]. RFA measurements essentially apply a bending load, which mimics the clinical load and direction and provides macroscopic information about the stiffness of the implant-bone interface, as bending is the most common type of loading for a dental implant [48].…”

“…RFA measurements essentially apply a bending load, which mimics the clinical load and direction and provides macroscopic information about the stiffness of the implant-bone interface, as bending is the most common type of loading for a dental implant [48]. The resonance frequency analysis technique has been extensively used in experimental and clinical research over the last 10 years for assessing primary stability, determining the adequate period of osseointegration before loading the implant, verifying whether sufficient stability has been attained in second-stage surgery, following-up the stability during the osseointegration process, as well as monitoring high-risk implants [21, 25-28, 30, 47, 49].…”

“…Regarding the implant geometry, in the study performed by Degidi et al (2007), XiVE ® implants showed high average RFA values due to their implant geometry and characteristic design to achieve a high primary stability. If the primary stability of an implant is very high, subtle changes in stiffness may not be evident [48]. The XiVE ® implants were selected in order to reduce the probability of implant failure due to constant ISQ measurements in early osseointegration stages.…”

Surface treatment of implants: primary stability

“…A recent review showed that many researchers have an inadequate understanding of the influence of implants with rough surfaces on primary stability 29 . Sul et al 27 , in their studies, found a relationship between primary stability values and the surface roughness of implants, also evident in the present work, which also shows higher values of initial stability in implants that underwent acid treatment, in comparison to the machined implants.…”
