Special Issue Information

Dear Colleagues,

Surface properties of biomaterials (e.g., roughness, wettability, antibacterial activity, chemical composition, electrical charge, crystallinity, modulus, hardness) play a significant role in biomaterials performance; including but not limited to its biocompatibility (particularly at biomaterial-tissue interface), protein adsorption, adhesion, and anti-inflammatory properties. As most bulk materials (i.e., metal alloys, polymers, ceramics) provide only mechanical stability for biomaterials, their surface modification plays a crucial role in addressing major performance issues such as lack of osseointegration, infections, toxicity, low corrosion/wear resistance, and insufficient antibacterial activity. Surface engineering via bulk materials surface properties modification and applying biocompatible coatings on bulk materials has demonstrated substantial synergistic improvements in performance and service life of biomaterials via alteration of their surface properties. These could help with the development of promising strategies to address specific clinical needs.

The present special issue aims to highlight the recent advances in surface engineering and biocompatible coatings for biomedical applications. Our goal is to publish at least ten high-quality articles, if we reach this number, the special issue may be published as a book. Original research articles and critical reviews are welcome in this special issue. Research areas may include (but not limited to) the following:

  • Mechanical and physical surface treatment: including grit blasting, polishing, shot peening, surface mechanical attrition treatment, laser peening, sputtering, laser/electron beam patterning, and plasma electrolyte oxidation.
  • Chemical and electrochemical surface treatment: including, etching, anodizing, electrophoretic deposition, and chemical vapor deposition.
  • Biocompatible coatings: including hydroxyapatite-based, bioactive glass-based, and polymer-based coatings.

We thank you for your interest and look forward to receiving your contributions.

The present study reveals for the first time the dry sliding wear behavior of a powder metallurgical pure titanium alloy (Cp-Ti) modified by shot peening. Cp-Ti samples were manufactured via powder metallurgy, and then their surface and subsurface features were modified using a custom-made, fully automated shot-peening system. The texture isotropy rate and the highest orientation angle of the shot-peened samples were 71.5% and 36°, respectively. The Abbott curves of the shot-peened surfaces revealed that the most common areal roughness value was 5.177 μm, with a frequency of 8.1%. Shot-peened surfaces exhibited an ~20% lower wear rate than unpeened surfaces under dry sliding wear, whereas the coefficient of friction was the same for both surfaces. Micro-ploughing, micro-cutting, oxidation, and three-body abrasion wear mechanisms were observed on the shot-peened and unpeened surfaces. High resolution 3D surface topographies of worn unpeened and shot-peened surfaces revealed micro-scratches and inhomogeneities along wear tracks, which are indicative of three-body abrasion mechanisms during contact. In addition, vertical and horizontal microcracks were visible just beneath the wear track, suggesting a clear indication of plastic deformation during contact. The cross-sectional hardness maps of shot-peened samples revealed the formation of a work-hardened surface layer with shot peening, which improved the wear resistance. These findings support that shot peening can be a useful tool to modify the surface and tribological properties of powder metallurgical Cp-Ti alloys. Full article

This study aimed to evaluate the stress distribution and mechanical behavior of miniplate designs to skeletal anchorage for the treatment of anterior open bite in adult patients. A complete hemimaxilla, teeth, brackets, transpalatal bar, and three miniplates were virtually modeled. I-, Y-, and T-shaped miniplates were installed in the area of the alveolar zygomatic crest. The assembly was constricted and three intrusive forces (2, 4, and 6 N) were applied to the maxillary molars and anchorage according to the miniplates. All materials were considered homogeneous, elastic, and linear; the mesh was 1,800,000 hexahedrons with 2,800,000 nodes on average. Displacement, maximum principal stress, and von Mises stress were evaluated according to the shape of the anchorage device and intrusive force. The miniplate configurations resulted in different stress and displacement intensities in the bone tissue and plate; these stresses were always located in the same regions and were within physiological limits. The Y-plate showed the best performance since its application generated less stress in bone tissue with less displacement. Full article
