“…However, heat treatment may, at specific temperature ranges, result in the formation of different crystalline phases which may negatively affect the elastic modulus and strength, predisposing for mechanical failure, as is the case with thermal treatment of Bioglass ® 45S5 [26]. Heat treatment of silicate-based BAG results in the release of stresses from the glass as there is a possibility of formation of the crystalline phases along with the residual glassy phases which might affect the mechanical properties [26]. Furthermore, the glass particles can be sintered into glass-ceramic scaffolds, the crystallization, however, reduces the ion dissolution and the bioactivity.…”

At present, researchers in the field of biomaterials are focusing on the oral hard and soft tissue engineering with bioactive ingredients by activating body immune cells or different proteins of the body. By doing this natural ground substance, tissue component and long-lasting tissues grow. One of the current biomaterials is known as bioactive glass (BAG). The bioactive properties make BAG applicable to several clinical applications involving the regeneration of hard tissues in medicine and dentistry. In dentistry, its uses include dental restorative materials, mineralizing agents, as a coating material for dental implants, pulp capping, root canal treatment, and air-abrasion, and in medicine it has its applications from orthopedics to soft-tissue restoration. This review aims to provide an overview of promising and current uses of bioactive glasses in dentistry.

“…The X-ray patterns of both, only sintered and the sintered and infiltrated substrates, are similar, showing cubic and tetragonal ZrO2 as crystal phases, Figure 7 (b-c). The infiltration of the substrates at 1350 °C did not promote the crystallization of the Bioglass 45S5, despite literature pointing to this possibility (Prasad et. al.…”

The aim of this work was to obtain porous ceramic parts based on Zirconia stabilized with 5mol.% Yttria (5Y-PSZ), suitable for the infiltration with bioactive glasses, using 3D printed sacrificial polymeric molds. In a first step, honeycomb structured molds were designed with the SolidWorks® software and manufactured by 3D printing using polylactic acid filaments (PLA). These molds were filled with a ceramic mass composed of 5Y-PSZ nanoparticles containing 3wt% polymeric binder and consolidated under pressure of 10MPa and then sintered at 1200 °C-30 min the polymeric molds were consumed. The obtained hexagonal-shaped, porous 5Y-TZP bodies were infiltrated with the bioactive glass 45S5, calcium sodium phosphosilicate, at 1350 °C. The materials were characterized by their relative density, their phase composition by X-ray diffraction analysis, and their microstructure by scanning electron microscopy (SEM-EDS), besides their mechanical properties of hardness and fracture toughness. Pre-sintered 5Y-PSZ substrates exhibit relative density around 75%, and 90% after sintering and Bioglass infiltration. The samples' microstructure is composed of a 5Y-PSZ matrix of sub-micrometric zirconia grains with an average size of 1.0 mm, besides the secondary infiltrated glassy phase homogeneously distributed, with a Ca/P ratio of 1.7, close to the ideal proportion for hydroxyapatite formation. In conclusion, sacrificial molding is an interesting route to obtaining dense Y-PSZ/Bioglass 45S5 composite in a honeycomb format.

“…Followed by density study, pulse echo method was used to measure various elastic moduli (Young's, Shear, Bulk, and Longitudinal), which provides an idea regarding the strength and interatomic potential of the biomaterial. The load bearing capacity of the prepared materials used for bone implants is assessed by their elastic properties 18 . The variation profile of Young's and shear moduli (48.02‐50.67 Gpa and 18.29‐18.82 Gpa) of the materials reflected the variation in the density profile.…”

In the case of longitudinal and bulk moduli, a slight variation was noted at 3.75 mol% of CaF 2 indicating the weakening of fluoride network (Figure 2 and Table 2).…”

Metals, ceramics, natural or synthetic polymers, and their composites are used as biomaterials aiding the clinician in the repair. Among these, biomaterials in orthopedics have very many demanding characteristics like tunable density, elasticity, and strength near to that of bone, bioresorbability and the ability to bond to live bone and not being toxic to the cells. Hench and Clark paved the way for preparing bioglasses and it is named as 45S5 bioglass. The 45S5 bioglass promotes osteogenesis by
