Abstract:
Bone, the organ that separates vertebrates from other living beings, is a complex tissue responsible of mobility, body stability, organ protection, and metabolic activities such as ion storage. Ceramic materials are appropriate candidates to be used in the fabrication of scaffolds for bone healing. Biocompatible ceramic materials may also be created to deliver biologically active substances aimed at maintaining, repairing, restoring, or boosting the function of tissues and organs in the organism. Glass-ceramic materials furnish flexible properties appropriate for some particular applications.

Abstract:
Calcium phosphate glasses have a high potential for use as biomaterials because their composition is similar to that of the mineral phase of bone. Phosphate glasses can dissolve completely in aqueous solution and can contain various elements owing to their acidity. Thus, the glass can be a candidate for therapeutic ion carriers. Recently, we focused on the effect of strontium ions for bone formation, which exhibited dual effects of stimulating bone formation and inhibiting bone resorption. However, large amounts of strontium ions may induce a cytotoxic effect, and there is a need to control th

Abstract Glass ionomer cements (GIC) are used in restorative dentistry and their properties (low heat during setting, adhesion to mineralised tissue and surgical metals) make them of great interest for bone applications.However, dental GIC are based on aluminium-containing glasses, and the resulting release of aluminium ions from the cements needs to be avoided for applications as bone cements.

Fluoride is an important mineral for hard tissues in the body and appropriate fluoride exposure and usage are beneficial to bone and tooth integrity. Fluoride increases both bone density and bone mass due to stimulation of bone formation and it is used as a treatment for osteoporosis.

Abstract:
This paper reviews the use of bioactive glasses as materials for periodontal repair. Periodontal disease causes bone loss, resulting in tooth loosening and eventual tooth loss. However, it can be reversed using bioactive glass, typically the original 45S5 formulation (Bioglass®) at the defect site. This is done either by plcing bioactive glass granules or a bioactive glass putty at the defect. This stimulates bone repair and causes the defect to disappear. Another use of bioactive glass in periodontics is to repair so-called furcation defects, i.e., bone loss due to infection at the intersecti

Abstract:
Bioactive glass scaffolds have been developed with interconnected macropore networks, with pore diameters in excess of 500µm and apertures in excess of 100µm, by foaming sol-gel derived bioactive glasses. Bioactive glasses bond to bone by forming a hydroxycarbonate apatite (HCA) layer on their surface on contact with body fluid, which is similar to the composition of the apatite in bone. The aim of this work was to investigate the how changing the atomic structure of the glass affects HCA layer formation. Scaffolds were synthesised at 3 sintering temperatures and were characterised using 29Si

Layer formation on the glass surface was found to vary with glass composition, sample shape and local condition of single particle/fiber. However, only some fibers or particles formed similar in vitro reaction layers as the plates. The product form did not chan

Abstract:
Bioactive glasses have been used for many years in the human body as bone substitute. Since bioactive glasses are not readily available in the form of endless thin fibres with diameters below 20 µm, their use is limited to mainly non-load-bearing applications in the form of particles or granules. In this study, the spinnability of four bioactive silicate glasses was evaluated in terms of crystallisation behaviour, characteristic processing temperatures and viscosity determined by thermal analysis. The glass melts were drawn into fibres and their mechanical strength was measured by single fibre

Abstract:
Bioactive materials for potential medical application have inspired and stimulated new searches. It has been confirmed that bioactive glasses bond to living bone through an apatite layer that precipitates on their surface in physiological media. These glasses normally constituted by silica, where the silicon is the network former, induce apatite nucleation by the formation of Si-OH groups. The presence of OH groups seems to be of utmost importance in the bioactive behaviour of materials. It was revealed that even metals, such as pure titania gel can bond to bone, if previously subjected to alk

Tricalcium phosphate (3CaO⋅P2O5, TCP) is known as a biodegradable material and already used clinically as important bone-repairing materials.

On the other hand, diopside (CaO⋅MgO⋅2SiO2) ceramic shows a potential of direct contact with bone and high mechanical strength, but low biodegradability. We expected that a glass-ceramic containing TCP and diopside show high bioactivity and high mechanical strength, as well as biodegradability.

Glass-ionomer cements (GIC) have been used in dentistry for over 30 years. In the past ten years they have also been developed for use as medical grade bone cements. However, concerns have been raised over the biocompatibility of GIC’s in non-dental applications. The release of Al3+ ions from the cement has been related to localized poor bone mineralisation and neurotoxicity. There is a need therefore to develop Al2O3-free cements. One potential route is the substitution of Al2O3 with Fe2O3 in the glass. An Fe2O3-based glass for use in GIC‘s was fabricated. The glass was found to differ consid

However, bioactive glasses are hard, brittle, and cannot be shaped easily. Therefore, in the past years, researchers have focused on the processing of new composites.
