Development of New Advanced Ti-Mo Alloys for Medical Applications

The use of titanium and titanium-based alloys with applications in implantology and dentistry has made remarkable progress in the promotion of new technologies and new materials that have been developed in recent years. This is justified thanks to their excellent mechanical, physical, and biological performance. Today’s generation promotes new titanium alloys, with nontoxic elements and long-term performance and without rejection of the human body. This book chapter describes new original compositions of Ti-based alloys for medical applications, with improved properties compared to existing classical alloys (C.p. Ti, Ti6Al4V, CoCrMo, etc.). The addition of nontoxic elements such as Mo, Si, Zr, and Ta brings benefits as reduced modulus of elasticity, increased corrosion resistance, and improved biocompatibility

Microstructural Characterization of the TiMoZrTa Alloy

In recent years, different types of titanium alloys have been investigated with the aim of using materials in biomaterials field, and Ti-Mo system alloys are very promising materials. Alloying titanium with biocompatible elements like Mo, Zr and Ta make then possible for these alloys to be used in medical applications. Microstructures of two TiMoZrTa alloys were investigated. Obtaining of this original recipes alloys was prepared using vacuum arc re-melting method afterwards composition of this alloys were verified by quantitative qualitative analysis EDX. Aim of this study is investigating aspects of microstructures TiMoZrTa alloys using optical and scanning electron microscopes, verifying the type of grains, that will show us the most important properties

New Trends in Bioactive Glasses for Bone Tissue: A Review

Bioactive glasses are very attractive materials, used for tissue engineering materials, usually to fill and restore bone defects. This category of biomaterials, show considerable potential for orthopaedic surgery because they can promote bone tissue regeneration. Many trace elements have been incorporated in the glass network, an example is metallic glasses to obtain the desired properties. Because of tolerable mechanical properties, and because they are able to bond to living bone and stimulate its regeneration, this bioactive glasses have a particular interest and are in a continuous research and improvement. The chapter presents the history of bioactive glasses, classification, include a summary of common fabrication methods, applications, surface coatings, applications and future trends in relation to human bone. This review highlight new trends and areas of future research for bioactive glasses
