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-ba… Show more
Titanium and its alloys are potential materials for orthopedic implant applications due to their appropriate biological and mechanical behavior. As biocompatibility and biomechanical compatibilities are essential parameters for determining a biomedical implant's performance and service life, this research review article discussed the novel Ti alloys with nontoxic and biocompatible alloying elements with an elastic modulus similar to the bone. Among Ti alloys, β-Ti alloys are appropriate for load-bearing implant applications due to lower elastic modulus and nontoxic elements, including Ti, Ta, Nb, Zr, Sn, and Mo. Even though the β-Ti alloys possess a lesser elastic modulus compared to other metallic biomaterials, two issues associated with β-Ti alloys that result in implant failure are that they still possess a higher elastic modulus than human bone and they have insufficient strength. Alloy composition and thermomechanical processing characteristics play a vital role in altering the mechanical properties and microstructure of β-Ti alloys. Hence, this review article emphasizes the alloying and thermomechanical processing effects on the mechanical properties and microstructure of β-Ti alloys.

“…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.…”
Taking into account the speed of industrial development and market request for novel biocompatible alloys, the urge of creating sustainable materials pushes the research forward. Among the many biomaterials that can be incorporated into the human body, in the class of metal alloys, titanium and titanium alloys are regarded as some of the most important biomaterials because of their resistance to the effects of body fluids, high tensile strength, flexibility, and corrosion resistance, as well as their unique combination of strength and biocompatibility. In present chapter several novel recipes for titanium alloys are presented and characterized (Ti-Mo-Si and Ti-Mo-Zr-Ta-Si systems).
