Special Issue: Ti-Based Biomaterials: Synthesis, Properties and Applications

Abstract

In the last half century, great attention has been paid to materials that can be used in the human body to prepare parts that replace failed bone structures. Of all materials, Ti-based materials are the most desirable, because they provide an optimum combination of mechanical, chemical and biological properties. The successful application of Ti biomaterials has been confirmed mainly in dentistry, orthopedics and traumatology. The Ti biomaterials provide high strength and a relatively low Young’s modulus. Titanium biocompatibility is practically the highest of all metallic biomaterials, however new solutions are being sought to continuous improve their biocompatibility and osseointegration. Thus, the chemical modification of Ti results in the formation of new alloys or composites, which provide new perspectives for Ti biomaterials applications. Great attention has also been paid to the formation of nanostructures in Ti-based biomaterials, which has leads to extremely good mechanical properties and very good biocompatibility. Additionally, the surface treatment applied to Ti-based biomaterials provides faster osseointegration and improve in many cases mechanical properties. The special issue “Ti-Based Biomaterials: Synthesis, Properties and Applications” has been proposed as a means to present recent developments in the field. The articles included in the special issue cover broad aspects of Ti-based biomaterials formation with respect to design theirs structure, mechanical and biological properties, as highlighted in this editorial.

Discovery of New Ti-Based Alloys Aimed at Avoiding/Minimizing Formation of α” and ω-Phase Using CALPHAD and Artificial Intelligence

“…• Design new manufacturing protocols with special emphasis on additive manufacturing [50][51][52][53][54][55][56].…”

“…Manufacturing of parts via additive manufacturing is a viable method, especially for users who need custom made implants [50][51][52][53][54][55][56][57]. The additive manufacturing route is also helpful in developing implants with lower Young's modulus and improved biocompatibility [51].…”

“…Several modes of designing new parts through additive manufacturing exist, such as selective laser beam, electron beam, etc. [50][51][52]56]. All of these methods have advantages and limitations [50][51][52]56].…”

“…[50][51][52]56]. All of these methods have advantages and limitations [50][51][52]56]. Optimization of operation param-eters plays a vital role in achieving targeted properties of a prosthetic/implant manufactured by additive manufacturing [50,53].…”

Facile Coating of HAP on Ti6Al4V for Osseointegration

“…This means that there is a poor bond between titanium and bones causing implant loosening which is highly undesirable. Therefore, surface modification plays a vital role in optimum osseointegration [15,20]. There are several techniques used in this regard such as: sand blasting [21,22], etching [23], electrochemical treatment [24], and thermal spray coatings [25].…”
