“…A free crack and thicker bioactive coating was obtained with the pneumatic spray deposition technique. This was very different to what happens with the thickness of the coating obtained by dip technique; although the dip coating technique allows the fabrication of very uniform and crack-free sol gel bioactive coatings, there is a restriction with respect to the thickness; the thickness obtained in previous investigations was not greater than 2 µm because the dip coating technique has a critical thickness, due to the evaporation of the solvents [23].…”

“…Average thickness measured in the images was approximately 47.7 ± 8 µm ( Figure 2). In past investigations [23], the dip coating technique was used to obtain TEOS-MTES with wollastonite particles, obtaining coatings with a homogeneous distribution of the wollastonite particles in the sol matrix, without flaws or cracks on the surface or around the wollastonite coatings. The thickness obtained with the dip coating technique was 1.10 ± 0.10 µm, four orders of magnitude lower than the thickness obtained through pneumatic spray.…”

“…Other authors have developed coatings on metals including particles as hydroxyapatite, zircon, bioglass, etc. [23,24]. However, coatings including wollastonite particles, not only show better bioactivity than others do [25,26], but also have interesting mechanical properties because the particles form [27] and distribution of the bioactive particles on the surface of the coating.…”

“…An in vivo study about bioactive coatings using wollastonite has been demonstrated that the bioactive sol-gel/wollastonite coating on surgical grade stainless steel promotes formation and growth of a new bone in the periphery of the implant, both in contact with the old bone (remodellation zone) and the marrow [23].…”

Bioactive coatings were obtained via the sol gel method and deposited on stainless steel AISI 316L using a pneumatic spray. TEOS and MTES were used as precursors, obtaining a hybrid sol; wollastonite bioactive particles were dispersed inside the sol. The corrosion resistance of the coatings was tested with potentiodynamic curves after immersion of the coatings in SBF for 7 and 40 days. It was possible to obtain coatings with a thickness of 47.7 ± 8 µm. In comparison with other methods of deposition, it was possible to obtain thicker coatings with the pneumatic spray deposition technique, giving the substrate a better protection factor against corrosion. After immersion in SBF (simulated physiologic fluid), the formation of an appetite film on the surface and inside the pores was observed. Deposition of the apatite film helps to promote Osseo integration, and the product formation inside the pores helps to improve corrosion resistance of the substrate.

Human shoulder is considered to be an important flexible and movable part in the human body. However, it is a wobble joint as its range of motion (ROM) is high. This unstable status causes the rate of joint injury. The processes leading to shoulder joint dysfunction are arthritis, hemiarthroplasty failure, and pseudoparalysis; in turn, one of the main factors contributing to these problems is rotator cuff tear (RCT). Reverse shoulder arthroplasty (RSA) may be a proper treatment for shoulder dysfunction and pain. This treatment that elevates shoulder movement has been augmented by recent advances in the development of the reverse shoulder prosthesis (RSP) design. The current review highlights the recent developments, revisions, and complications. The review of the published literature has been done to determine the overall rates of problems, complications, reoperations, and revisions after RSA. Furthermore, this review discusses the problems concerning RSP, shoulder joint replacement, and improvement in shoulder joint movement after arthroplasty. Ultimately, an outcome of different endeavors of the researcher was summarized. The endeavor of the current review indicates that RSA is a valuable alternative that can increase forward elevation, improve function, and relieve pain.

Compared with stainless steel and Co-Cr-based alloys, Ti and its alloys are widely used as biomedical implants due to many fascinating properties, such as superior mechanical properties, strong corrosion resistance, and excellent biocompatibility. After briefly introducing several most commonly used biomedical materials, this article reviews the recent development in Ti alloys and their biomedical applications, especially the low-modulus β-type Ti alloys and their design methods. This review also systemically investigates the recently attractive progress in preparation of biomedical Ti alloys, including additive manufacturing, porous powder metallurgy, and severe plastic deformation, applied in the manufacturing and the influenced microstructures and properties. Nevertheless, there are still some problems with the long-term performance of Ti alloys, and therefore several surface modification methods are reviewed to further improve their biological activity, wear resistance, and corrosion resistance. Finally, the biocompatibility of Ti and its alloys is concluded. Summarizing the findings from literature, future prediction is also conducted. Darmstadt. His current research interest is focusing on the metal additive manufacturing (e.g. selective laser melting, electron beam melting), titanium alloys and composites, and processing-microstructure-properties in high-performance materials.
