The evolution of implant stability in bone tissue remains difficult to assess because remodeling phenomena at the bone-implant interface are still poorly understood. characterization biomechanical properties newly formed vicinity implants microscopic scale is importance order better understand osseointegration process. objective this study investigate potentiality micro-Brillouin scattering techniques differentiate mature and elastic following a multimodality approach using histological...
The characterization of the biomechanical properties newly formed bone tissue around implants is important to understand osseointegration process. objective this study investigate evolution hardness and indentation modulus as a function healing time. To do so, nanoindentation device employed following multimodality approach using histological analysis. Coin-shaped were placed in vivo at distance 200 μm from cortical surface, leading an initially empty cavity * 4.4 mm. Three New Zealand White...
Dental implants are widely used in the clinic. However, there remain risks of failure, which depend on implant stability. The aim this paper is to compare two methods based resonance frequency analysis (RFA) and quantitative ultrasound (QUS) that at assessing Eighty-one identical dental were inserted iliac crests 11 sheep. QUS RFA measurements realized after different healing times (0, 5, 7, 15 weeks). results obtained with (respectively RFA) method significantly when comparing consecutive...
The surface plasmon wave is a confined at the interface between dielectric and metal. excitation of resonance (SPR) on gold thin film discussed within Kretschmann configuration, where coupling with light achieved by means prism in total reflection. electromagnetic principles are detailed simple experimental setup described that can be used for laboratory experiments senior students third or fourth year university. This experiment allows accurate determination angle extinction discussion...
The characterization of the biomechanical properties newly formed bone tissue around implants is important to understand osseointegration process. objective this study investigate evolution elastic as a function healing time. To do so, nanoindentation and micro-Brillouin scattering techniques are coupled following multimodality approach using histological analysis. Coin-shaped were placed in vivo at distance 200 µm from cortical surface, leading an initially empty cavity. Two rabbits...
Abstract Background Resonance frequency analyses and quantitative ultrasound methods have been suggested to assess dental implant primary stability. Purpose The purpose of this study was compare the results obtained using these two techniques applied same implants inserted in various bone phantoms. Materials Methods Different values trabecular density cortical thickness were considered effect quality on respective indicators (UI ISQ). insertion depth final drill diameter also investigated....
Dental implant stability is an important determinant of the surgical success. Quantitative ultrasound (QUS) techniques can be used to assess such properties using acting as a waveguide. However, interaction between ultrasonic wave and remains poorly understood. The aim this study investigate sensitivity response quality quantity bone tissue in contact with surface. 10 MHz clinical practice was simulated axisymmetric three-dimensional finite element model, which validated experimentally....

Purpose Quantitative ultrasound (QUS) and resonance frequency analyses (RFA) are promising methods to assess the stability of dental implants. The aim this in vivo preclinical study is compare results obtained with these two techniques bone-implant contact (BIC) ratio, which gold standard implant stability.
Abstract The evolution of bone tissue quantity and quality in contact with the surface orthopedic dental implants is a strong determinant surgical outcome but remains difficult to be assessed quantitatively. aim this study was investigate performance quantitative ultrasound (QUS) method measure bone-implant interface (BII) properties. A dedicated animal model considering coin-shaped titanium two levels roughness (smooth, S = 0.49 µm rough, 3.5 µm) allowed work reproducible geometry planar...
Poly(dimethyl siloxane) (PDMS) is one of the most widely used materials in biomedical field. Despite its numerous advantages, hydrophobic character promotes bacterial adhesion and biofilm formation. For breast implants, biocompatibility challenged due to formed around implant that can degenerate severe capsular contracture over time. Thus, laboratory has set up strategies prevent contamination by grafting covalently hydrophilic bioactive polymers on surface implants. In this study,...
Abstract Titanium implants are widely used in dental and orthopedic surgeries. However, implant failures still occur because of a lack stability. The biomechanical properties bone tissue located around the need to be assessed better understand osseointegration phenomena anticipate failure. aim this study was explore spatiotemporal variation microscopic elastic newly formed close an implant. Eight coin-shaped Ti6Al4V were inserted into rabbit tibiae for 7 13 weeks using vivo model allowing...
