Development of New Advanced Ti-Mo Alloys for Medical Applications

Abstract

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.

A review on β-Ti alloys for biomedical applications: The influence of alloy composition and thermomechanical processing on mechanical properties, phase composition, and microstructure

“…89 The advantages, limitations, and applications of metallic biomaterials are presented in Table 3. 73,81,[90][91][92]…”

Novel Titanium Alloys for Tissue Engineering

“…They serve as popular alternatives for hard tissue in artificial joints, bones, and dental implants. The low elastic modulus of titanium and its alloys is often considered advantageous in terms of biomechanics, as it can lead to reduced stress shielding [3][4][5][6][7]. Another noteworthy characteristic of titanium-based materials is their tendency to form an extremely thin, adherent, and protective coating of titanium oxide.…”

“…However, because they are inert, materials placed in bone will cause local and systemic biological reactions. An adaptive and reactive process involving several factors will be triggered by host reactions to joint replacement and fixation materials [3][4][5][6][7][8][9].…”

“…However, revision procedures for hip and knee implants have also grown, in addition to replacement surgery. These painful revision procedures are incredibly costly, and they also have a very poor success rate [2][3][4][5][6][7].…”

“…Polymeric materials have historically been employed for low-friction articulated surfaces due to their flexibility and stability. As a result, titanium becomes one of the most attractive engineering materials for several applications, and due to their exceptional qualities, in its biocompatibility, low modulus and corrosion resistance [5][6][7][12][13][14]. Implant materials should not be harmful and should not result in allergic or inflammatory responses in people.…”
