“…Besides, general knowledge on composite mechanics suggests that any high aspect ratio particles, such as whiskers or fibers, significantly improve the modulus at a lower loading. Thus, some attempts have been already performed to prepare biocomposites containing whisker-like [ 167 , 168 , 169 , 170 , 171 , 172 , 173 ] or needle-like [ 174 , 175 , 176 , 177 ] CaPO 4 , as well as CaPO 4 fibers [ 178 ].…”

“…Biocomposites made from CaPO 4 and various types of resins appeared to possess comparable mechanical and biological properties to typical PMMA cement, leading to potential uses for implant fixation [ 170 , 172 , 475 , 476 , 477 ]. To improve the mechanical properties of the self-setting CaPO 4 -based formulations and stabilize them at the implant site, various researchers have resorted to formulations that set in situ , primarily through crosslinking reactions of the polymeric matrix.…”

The state-of-the-art on calcium orthophosphate (CaPO4)-containing biocomposites and hybrid biomaterials suitable for biomedical applications is presented. Since these types of biomaterials offer many significant and exciting possibilities for hard tissue regeneration, this subject belongs to a rapidly expanding area of biomedical research. Through the successful combinations of the desired properties of matrix materials with those of fillers (in such systems, CaPO4 might play either role), innovative bone graft biomaterials can be designed. Various types of CaPO4-based biocomposites and hybrid biomaterials those are either already in use or being investigated for biomedical applications are extensively discussed. Many different formulations in terms of the material constituents, fabrication technologies, structural and bioactive properties, as well as both in vitro and in vivo characteristics have been already proposed. Among the others, the nano-structurally controlled biocomposites, those containing nanodimensional compounds, biomimetically fabricated formulations with collagen, chitin and/or gelatin, as well as various functionally graded structures seem to be the most promising candidates for clinical applications. The specific advantages of using CaPO4-based biocomposites and hybrid biomaterials in the selected applications are highlighted. As the way from a laboratory to a hospital is a long one and the prospective biomedical candidates have to meet many different necessities, the critical issues and scientific challenges that require further research and development are also examined.

“…However, when mixed with HA microparticles, these nanoparticles can increase the total filler loading to yield improved mechanical properties. − Other shapes of HA such as whiskers and nanofibers (Figure b) were of interest for composite development. The high-aspect-ratio filler reinforced dental RBCs showed better mechanical properties than those reinforced with spheroidal HA. − Recently, a novel urchin-like hydroxyapatite (UHA, Figure a) was prepared through microwave irradiation and was applied as a dental filler. UHA was embedded in resin matrix, and displayed strong interfacial adhesion.…”

Dental resins represent an important family of biomaterials that have been evolving in response to the needs in biocompatibility and mechanical properties. They are composite materials consisting of mostly inorganic fillers and additives bound together with a polymer matrix. A large number of fillers in a variety of forms (spheroidal, fibrous, porous, etc.) along with other additives have been studied to enhance the performance of the composites. Silane derivatives are attached as coupling agents to the fillers to improve their interfacial properties. A review of the literature on dental composite fillers seems to suggest that each of the fillers tested presents its own strengths and weaknesses, and often combinations of these yield resin composites with the desired balance of properties. Additives such as nanotubes, whiskers, fibers, and nanoclusters have been shown to enhance the properties of these hybrid materials, and their use in small fractions may enhance the overall performance of the dental resin materials.

“…The silanized UHA remarkably improved the mechanical properties than unfilled resin matrix. UHA with silica nanoparticles increased the mechanical properties significantly [24]. However, the mismatch of refractive index of HA with resin matrix could result in reduced monomer conversion and cure depth [25].…”

Dental composite fillings are most popular fillings wherein various fillers have been suitably dispersed in a polymerizable resin. Major challenges are to make choice of suitable filler and their distribution in the resin matrix in the development of the dental fillings. Apart from traditional fillers ceramic whiskers, glass fibres, branched fibres and nanoporous powders have also been investigated as fillers in dental composites. Recently, ceramic, and glass-ceramic fillers are attracting attention of the researchers due to their suitable combination of material properties. In the current paper, the prospect of ceramic and glass-ceramics as fillers in fabricating dental composites has been reviewed.
