“…In 1982, Kokubo et al [3] introduced silicate glass-ceramics, which contain MgO, CaO, SiO 2 and P 2 O 5 , and have been used as bone defect fillers, and for vertebral and iliac crest replacement. Since then, other types of silicate bioceramics have been proposed, which mainly fall into two categories: silica-based bioactive glasses, such as BG, whose composition contains different oxides, and crystalline calcium silicate ceramics, including wollastonite (b-CaSiO 3 ), pseudowollastonite (a-CaSiO 3 ), dicalcium silicate (Ca 2 SiO 4 ) and tricalcium silicate (Ca 3 SiO 5 ) [4]. Here, we will discuss the application of surface characterization tools mainly to materials in the first category, although we will also provide examples from the second.…”

The success of an implanted prosthetic material is determined by the early events occurring at the interface between the material and the body. These events depend on many surface properties, with the main ones including the surface's composition, porosity, roughness, topography, charge, functional groups and exposed area. This review will portray how our understanding of the surface reactivity of silicate bioceramics has emerged and evolved in the past four decades, owing to the adoption of many complementary surface characterization tools. The review is organized in sections dedicated to a specific surface property, each describing how the property influences the body's response to the material, and the tools that have been adopted to analyse it. The final section introduces the techniques that have yet to be applied extensively to silicate bioceramics, and the information that they could provide.

“…However, the compressive strength and fracture toughness of TTCP were considerably lower than the compressive strength (between 90 and 224 MPa) and fracture toughness (2-12 MPa•m 1/2 ) of cortical bone [28,29]. In the research, as the power of the laser increased, the compressive strength and fracture toughness of the scaffold decreased accordingly because of the abnormal grains that developed during the growth process [30]. The Vickers hardness was 371 HV at 6 W and 405 HV at 9 W. However, the Vickers hardness decreased to 400 HV at 10 W. The hardness can reflect the elastic and plastic deformation resistance of TTCP [31].…”

Tetracalcium phosphate (TTCP), a potential biological scaffold material, has attracted increasing interest for bone regeneration applications due to its good biodegradability and biocompatibility. In this research, three-dimensional porous TTCP scaffolds were manufactured via selective laser sintering (SLS), and an in-depth and meticulous study on the influence of laser power on the microstructure and mechanical properties of TTCP scaffolds was performed. The results showed that the TTCP particles fused together and formed a solid object due to the decrease in the number of micro-pores in the scaffold as the laser power increased from 6 W to 9 W. The maximum compressive strength that the scaffold could withstand and the strength of the fracture toughness were 11.87 ± 0.64 MPa and 1.12 ± 0.1 MPa·m1/2, respectively. When the laser power increased from 9 W to 10 W, the TTCP grains grew abnormally, resulting in diminished mechanical properties. The bioactivity tests showed that the surfaces of the scaffolds were entirely covered by bone-like apatite layers after soaking in simulated body fluid (SBF) for three days, indicating that the scaffolds exhibit excellent bioactivity. Moreover, cell experiments showed that the TTCP scaffolds had good biocompatibility. This study indicated that SLS-fabricated TTCP scaffolds may be a promising candidate for bone regeneration applications.

Calcium silicate-based cements have superior sealing ability, bioactivity, and marginal adaptation, which make them suitable for different dental treatment applications. However, they exhibit some drawbacks such as long setting time and poor handling characteristics. To overcome these limitations calcium silicates are engineered with various constituents to improve specific characteristics of the base material, and are the focus of this review. An electronic search of the PubMed, MEDLINE, and EMBASE via OVID databases using appropriate terms and keywords related to the use, application, and properties of calcium silicate-based cements was conducted. Two independent reviewers obtained and analyzed the full texts of the selected articles. Although the effects of various constituents and additives to the base Portland cement-like materials have been investigated, there is no one particular ingredient that stands out as being most important. Applying nanotechnology and new synthesis methods for powders most positively affected the cement properties.
