Computational simulation of dental implant osseointegration through resonance frequency analysis

Mandibular bone remodeling induced by dental implant

“…Such clinical studies often make use of Osstell instrument and reported an increase in resonance frequency with increased bone remodeling. Perez et al (2008) demonstrated that the osseointegration leads to an increase in resonance frequency and yields a stabilized condition starting from week 7 at 4.5 KHz. In general, the resonance frequency test to determine bone remodeling and implant stability appears to have credibility both clinically and computationally.…”

Finite element based bone remodeling and resonance frequency analysis for osseointegration assessment of dental implants

“…Basically, the stability of implantation is largely associated with osseointegration and peri-implant bone remodeling developed during healing [23]. It is generally agreed that the initial implant stability can be attained through mechanical interlocking between the implant and bone, while the long-term implant stability can be gained by the bone apposition surrounding the implant-bone interface [17,24]. There have been various ways of assessing the implant stability.…”

“…natural or resonance frequency) during an osseointegration and remodeling process [24]. In other words, RFA could be considered an effective tool to validate the computational remodeling protocol established.…”

Bone ingrowth on the surface of endosseous implants. Part 1: Mathematical model

“…In fact, the majority of the existing works of this type on bone implants have focused on the biomechanical nature of the problem, trying to draw conclusions from the change of the mechanical state of bone after placement of implants, evaluating the influence of mechanical factors such as the geometry of the implant or magnitude of loading and proposing phenomenological models for the study of bone ingrowth or remodelling Moreo et al, 2007b;Pérez et al, 2007;Daas et al, 2007;Liao et al, 2008). Although the interest of these works is unquestionable, it is the authors' opinion that mechanobiological models in which specific biological processes coupled with mechanics are modelled together with their influence on the structure and mechanical properties of tissues constitute a richer source of information for the understanding of many problems in biomedical sciences.…”
