This book was released on 2021 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, advanced materials research in implantable metallic devices for bone tissue engineering has significantly influenced orthopedic and dental applications. However, these devices' practical usage still has several challenges concomitant to acquiring and retaining biological fixation at the implant site. An important goal of current biomaterials research is to induce and accelerate bone tissue growth around the implants. In addition to rapid wound healing at the surgery site, these implants must have adequate biomechanical characteristics. This dissertation elaborates on investigating the effect of developing surface charge on Titania (TiO2) nanotubes and assessed it's in vitro and in vivo early-stage osseointegration. Growing TiO2 nanotubes on commercially pure titanium led to the introduction of bioactivity in an otherwise bioinert material via physical anchoring surface for the bone tissue to bond. Surface charge enhances makes the surfaces more hydrophilic and better suited for cellular interactions. We have further explored the effect of compositional modifications through alloying titanium (Ti) with tantalum (Ta) to induce bioactivity. Comparisons among porous and dense Ti-Ta with and without surface modification through TiO2 nanotubes were drawn to assess the variation in cellular interactions and in vivo early-stage bone regeneration.Our results indicate a stored charge of 37.15 ℗ł 14 mC/cm2 for TNT surfaces. Histomorphometric analyses show ~40% increase in mineralized bone formation around the TNT-P implants than the TNTs at 5 weeks, indicative of accelerated bone remodeling cycle. We have shown comparable performance of porous Ta and surface-modified porous Ti64 implants towards early-stage osseointegration at 5 weeks post-implantation through seamless bone-material interlocking. However, a continued and extended efficacy of porous Ta is found in terms of higher osteoid formation at 12 weeks post-surgery. Alloying Ta with Ti during additive fabrication resulted in an overall decrease in elastic modulus of Ti (Ti: 110GPa, 25Ta: 63℗ł 5.5 GPa), helping circumvent any mechanical instability that can arise from a very high mismatch in modulus. Consequently, porous Ti-Ta alloys exhibited increased osseous tissue formation at the implant-bone interface (70% trabecular bone formation in rabbit femur), providing evidence of the superior biological performance of the material towards early-stage bone healing.
Download or read book Customized Artificial Implants Bionic Design and Multiscale Evaluation written by Zhenxian Chen and published by Frontiers Media SA. This book was released on 2024-05-24 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: Artificial implants have been commonly used to replace or fix damaged tissue in orthopedics. However, due to the inter-individual differences and the complexities of anatomical structures and load conditions, traditional implants cannot meet the clinical requirements. In recent years, questions relating to customized artificial implants have been getting more and more attention from the research community. Challenges to implementing precision design and evaluation arise not only from the design need of considering bionic structures, kinematical function, mechanical performances, and biological functional similarity but also from the multiscale comprehensive evaluation, the latter involves biomechanics and biotribology of musculoskeletal systems from macro musculoskeletal multibody dynamics to micromechanics of porous structures. Established analysis technologies such as musculoskeletal multibody dynamics modeling and neuromusculoskeletal modeling are being well developed and evolved through combining/coupling with finite element analyses and, more recently, by novel artificial intelligence approaches.
Download or read book 3D Printing in Bone Surgery written by Carmine Zoccali and published by Springer Nature. This book was released on 2022-03-05 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: Filling a gap in the literature, this is the first book to comprehensively discuss 3D printing applied to bone surgery. It provides both the scientific basics and practical applications, with a special focus on 3D-printed, custom-made titanium prostheses (3DPCMP) used for bone reconstruction following tumor resection. Initially applied to pelvic and scapular prostheses – because of their of highly complex anatomy – this technology is increasingly being adopted in other fields of orthopedics, such as limb surgery, traumatology and degenerative diseases. Throughout the book, experts from various fields share their knowledge, describing 3D printing applied to the reconstruction of different bone segments, reviewing each application and comparing it with traditional reconstruction. They also present real-world case studies from their clinical practice. Uniquely responding to the growing interest surrounding 3D printing for bone reconstruction, this book is invaluable for orthopedic, neuro- , head and neck as well as maxillofacial surgeons wishing to gain insights into this new and promising field.

Download or read book Additive Manufacturing of Titanium Alloys written by Bhaskar Dutta and published by Butterworth-Heinemann. This book was released on 2016-06-17 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Additive Manufacturing of Titanium Alloys: State of the Art, Challenges and Opportunities provides alternative methods to the conventional approach for the fabrication of the majority of titanium components produced via the cast and wrought technique, a process which involves a considerable amount of expensive machining. In contrast, the Additive Manufacturing (AM) approach allows very close to final part configuration to be directly fabricated minimizing machining cost, while achieving mechanical properties at least at cast and wrought levels. In addition, the book offers the benefit of significant savings through better material utilization for parts with high buy-to-fly ratios (ratio of initial stock mass to final part mass before and after manufacturing). As titanium additive manufacturing has attracted considerable attention from both academicians and technologists, and has already led to many applications in aerospace and terrestrial systems, as well as in the medical industry, this book explores the unique shape making capabilities and attractive mechanical properties which make titanium an ideal material for the additive manufacturing industry. Includes coverage of the fundamentals of microstructural evolution in titanium alloys Introduces readers to the various Additive Manufacturing Technologies, such as Powder Bed Fusion (PBF) and Directed Energy Deposition (DED) Looks at the future of Titanium Additive Manufacturing Provides a complete review of the science, technology, and applications of Titanium Additive Manufacturing (AM)

Download or read book Handbook of Research on Advanced Functional Materials for Orthopedic Applications written by Ranjith, R. and published by IGI Global. This book was released on 2023-08-29 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scaffold bone replacements are a safe and effective way to cure bone abnormalities, and porous scaffolds can be manufactured using additive manufacturing technology. When scaffolds are implanted in a damaged location, they quickly connect to the host tissue and integrate, stimulating bone production and development. The qualities of porous titanium must be matched to the properties of human bones (i.e., age, sex, and hormones). Using subtractive manufacturing, it is extremely difficult to create the complicated porous structure necessary for the desired characteristic. The Handbook of Research on Advanced Functional Materials for Orthopedic Applications highlights current research pertinent to the orthopedic applications of additive-produced scaffolds in order to consider the latest breakthroughs in the synthesis and multifunctional applications of scaffolds. Covering key topics such as tissue, additive manufacturing, and biomaterial, this major reference work is ideal for industry professionals, engineers, researchers, academicians, practitioners, scholars, instructors, and students.
