“…After 50, 75, and 90 % cold rolling, the alloy shows a three-phase structure of α + β + ω str . The generation of α and ω str was related to the stress--induced transformation (β → α + ω str ) [24,[40][41][42][43]. The phases and phase volume fractions of alloys under various processing conditions are listed in Table 2.…”

“…Thermomechanical treatment (TMT) has attracted attention as an effective process to improve the mechanical performances of Ti alloys. The first stage of TMT is to deform the alloy (rolling or forging), which can achieve the effects of strain hardening and grain refinement [23], and then improve the strength of the material [24][25][26]. It is worth noting that the β-type Ti alloy with low phase stability (meta-stable β-type Ti alloy) would produce the stress-induced martensitic transformation (β → α ) during the deformation process, which can reduce the elastic modulus of the alloy [24].…”

In this work, different thermomechanical treatment conditions were used to improve the mechanical performances of Ti-25Nb-8Sn. During cold rolling treatment (50, 75, and 90 %), as-cast Ti-25Nb-8Sn underwent a stress-induced phase transformation from a single β phase to a three-phase structure of α + β + ωstr. After the subsequent aging treatment, Ti-25Nb--8Sn presents three-phase β + α + ωiso (at 250 and 400 • C, for 30 min) and two-phase β + α (at 600 • C, for 30 min). At lower aging temperatures (250 and 400 • C), yield strength/modulus (× 1000) ratios of Ti-25Nb-8Sn are dramatically improved with a maximum increase of 143 %, from 9.06 (as-cast) to 16.2-22.0. Under various thermomechanical treatment conditions in this study, the results show that Ti-25Nb-8Sn has excellent yield strength/modulus (× 1000) ratio (∼ 22) and corrosion resistance after 90 % cold rolling and subsequent aging treatment at 250 and 400 • C for 30 min.

“…BIOMATERIAL candidates for long-lasting dental implantology must demonstrate a combination of low elastic modulus, [1][2][3][4] biocompatibility, [5][6][7] and corrosion resistance [8][9][10] when exposed to the various organic and inorganic substances present in the human body. Meeting these requirements are Ti-based materials that lack potentially toxic elements such as commercially pure a Ti (CP-Ti) [11,12] and metastable b Ti alloys with ultra-low elastic modulus that are currently under development.…”

“…[20][21][22][23][24] Techniques based on typical methods of deformation, such as multiple-stage cold rolling, are of particular interest as they can be scaled up to the industrial level. [6,[25][26][27] The huge number of grain boundaries and dislocations introduced during large plastic deformation affect the material's mechanical properties as well as functional features such as corrosion resistance. [20,28,29] It is well known that the high corrosion resistance of Ti and its alloys is governed by the presence of a nanometric protective oxide layer on their surfaces.…”

Two approaches can be taken when designing properties of the native oxide layers formed on Ti-based biomedical materials: (i) changing the chemical composition of the substrate by adding biocompatible, valve alloying elements, and (ii) changing the microstructure of the substrate—especially its level of defectiveness—through large plastic deformation. However, especially in the aggressive fluoridated oral environment, it is still unknown what factor is more effective in terms of enhancing oxide layer protectiveness against biocorrosion: (i) the presence of valve alloying elements, or (ii) a high number of structural defects. To gain knowledge about the separate influence of both of these factors, surface properties were examined for commercially pure Ti and Ti–Nb–Ta–Zr alloy in microcrystalline state as well as after multiple-pass cold rolling, a process that can be readily scaled up to the industrial level. This study showed that while valve-alloying elements and structural defects individually have a beneficial effect on Ti oxide layer properties in fluoridated medium, they not have to act in a synergistic manner. These findings have to be taken into account when designing future Ti-based dental materials together with analyzing their mechanical performance with respect to mechanical strength and elastic properties.

Summary The cementum is the outermost layer of hard tissue covering the dentin within the root portion of the teeth. It is the only hard tissue with a specialized structure and function that forms a part of both the teeth and periodontal tissue. As such, cementum is believed to be critical for periodontal tissue regeneration. In this review, we discuss the function and histological structure of the cementum to promote crystal engineering with a biochemical approach in cementum regenerative medicine. We review the microstructure of enamel and bone while discussing the mechanism underlying apatite crystal formation to infer the morphology of cementum apatite crystals and their complex structure with collagen fibers. Finally, the limitations of the current dental implant treatments in clinical practice are explored from the perspective of periodontal tissue regeneration. We anticipate the possibility of advancing periodontal tissue regenerative medicine via cementum regeneration using a combination of material science and biochemical methods.
