Review ArticleOpen accessIn the keywordsNews in Bone Modeling for Customized Hybrid Biological Prostheses DevelopmentRelly Victoria Virgil Petrescu, Raffaella Aversa, Valeria Perrotta et al.The complex biomechanics and morphologies of the femur proximal epiphysis are presented. The nature and fine morphology of the femur head and its structural behavior have been investigated. Isotropic and orthotropic trabecular structures have been associated with oriented compression and tensioned areas of the femur head FEM models. These isotropic/orthotropic trabecular morphologies and their allocations govern the stress and strain … …OnLine Journal of Biological Sciences, Vol. 21, Issue 2 · 14 Jun 2021 · 6,351 accessesView PDFCite
Research ArticleOpen accessIn the keywordsBiomimetic Finite Element Analysis Bone Modeling for Customized Hybrid Biological Prostheses DevelopmentAversa Raffaella, Florian Ion T. Petrescu, Relly Victoria V. Petrescu, Apicella AntonioThe human femur shows a high capacity to withstand external stresses and it is due to the mass distribution, morphology, and orthotropic behaviors of trabecular and cortical bone. Faithful modeling of the femur accounting for bone distribution and material orthotropic behavior is presented. The use of biofidel model is aimed to develop an "in silico" tool that could enable the … …American Journal of Applied Sciences, Vol. 13, Issue 11 · 30 Nov 2016 · 8,980 accessesView PDFCite
Research ArticleOpen accessIn the keywordsBiofidel FEA Modeling of Customized Hybrid Biological Hip Joint Prostheses, Part I: Biomechanical Behavior of Implanted FemurRaffaella Aversa, Florian Ion T. Petrescu, Relly Victoria V. Petrescu, Antonio ApicellaBiofidel femur Finite Element Models have been developed using specific combination of Computer Tomography segmentation and solid modeling software tools able to represent bone physiology and structural behavior. These biofidel Finite Element Models (FEM) is used to evaluate the modification of the physiological stress distribution in a prosthesized femur and to assess new design criteria for the development of biomimetic … …American Journal of Biochemistry and Biotechnology, Vol. 12, Issue 4 · 16 Dec 2016 · 8,716 accessesView PDFCite
Research ArticleOpen accessIn the abstractHybrid Ceramo-Polymeric Nano-Diamond CompositesAntonio Apicella, Raffaella Aversa, Florian Ion Tiberiu PetrescuThis paper discusses a new class of bio-mechanical scaffolds active for tissue engineering based on a nano-diamond-filled hydrophilic polymer matrix. The new biomaterials used have special mechanical and biological properties for which they should be extensively studied for their use for various advanced biomedical applications. The new hybrid material has been prepared using 2 and 5% by volume of detonating … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 21 May 2018 · 8,616 accessesView PDFCite
Research ArticleOpen accessIn the abstractExtracting the Potential Features of Digital Panoramic Radiograph Images by Combining Radio Morphometry Index, Texture Analysis, and Morphological FeaturesEnny Itje Sela, SutarmanOsteoporosis is a type of disease that is not easily detected visually. It contributes to bone fracture and so early diagnosis is particularly important to prevent bone fracture. An integrated approach for extraction of cortical and trabecular bone on the digital panoramic radiograph (DPR) images was proposed to screen osteoporosis. We performed radio morphometry index (RMI), texture analysis, and morphology … …Journal of Computer Science, Vol. 14, Issue 2 · 7 Dec 2017 · 8,026 accessesView PDFCite
Research ArticleOpen accessIn the abstractFlexible Stem Trabecular ProsthesesRaffaella Aversa, Florian Ion T. Petrescu, Relly Victoria V. Petrescu, Antonio ApicellaThe complex biomechanics and morphology of the femur proximal epiphysis are presented. This specific region in human femur is characterized by a high flexibility compared to that of other primates, since evolved lighter and longer due to the human verticalposition and more balanced loading. The nature and fine morphology of the femur head and its structural behavior have been investigated. … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 22 Dec 2016 · 7,855 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiofidel FEA Modeling of Customized Hybrid Biological Hip Joint Design Part II: Flexible Stem Trabecular ProsthesesRaffaella Aversa, Florian Ion T. Petrescu, Relly Victoria V. Petrescu, Antonio ApicellaNew biomechanical criteria for the design of biomimetic hip joint prostheses are presented. Biofidel Finite Element Models have been used both to correctly analyze femur physiological and structural behavior and to assess a new design criterion for the development of innovative hybrid biological hip prostheses. Proper identification of isostatic lines and isorigidity regions for the sintered metal trabecular lattices distribution … …American Journal of Biochemistry and Biotechnology, Vol. 12, Issue 4 · 16 Dec 2016 · 8,612 accessesView PDFCite
Research ArticleOpen accessIn the abstractBone Microarchitecture by Dentistry Digital X-Ray (BµA-DDX) Software: A Pilot Study of the Analysis of Bone Density using Digital Dental X-RaysAdriane Yaeko Togashi, Adair Santa Catarina, Lucas Renato Piana Batistussi, Guilherme CoelhoThe Bone Microarchitecture by Dentistry Digital X-Ray (BµA-DDX) software was designed to determine jaw bone quality using digital dental X-rays. In order to identify patients with a suspicion of low bone density, a system was developed to evaluate bone microarchitecture through the analysis of samples collected in digital panoramic X-rays. The samples were collectedat two sites of the mandible: alveolar … …Current Research in Dentistry, Vol. 6, Issue 2 · 23 Feb 2016 · 7,471 accessesView PDFCite
