“…The sol‐gel route was employed for the development of a 60SiO 2 −3P 2 O 5 −14Al 2 O 3 −6CaO–7Na 2 O–10K 2 O (wt %) GCs and a related composite material combining this GC with a 58SiO 2 −33CaO–9P 2 O 5 (wt %) bioactive glass . Their method resulted in a homogeneous microporous GC composite which can be applied as a coating on commercial dental ceramic substrates .…”

The interest around bioactive glass-ceramics (GCs) has grown significantly over the last two decades due to their appropriate biochemical and mechanical properties. The intense research effort in this field has led to some new commercial products for biomedical applications. This review article begins with the basic concepts of GC processing and development via controlled heat treatments of monolithic pieces or sinter-crystallization of powdered glasses. We then go on to describe the processing, properties, and applications of some commercial bioactive GCs and discuss selected valuable reported researches on several promising types of bioactive GCs. The article finishes with a section on open relevant research directions for bioactive GC development.

“…Bioactive dental materials have been developed over the last decades (Chatzistavrou et al 2010). According to Hench, bioactive glass produces a specific biological response at the interface of the material which results in the formation of a bond between the tissues and the material (Chatzistavrou et al 2012;Hench and Paschall 1973). Ceramic materials are regularly used in dental restoration, which have specific properties such as similarity with natural tooth structure, wear resistance, high mechanical strength and durability in the oral environment.…”

Kalsilite glass-ceramic composites have been prepared by a mechanochemical synthesis process for dental veneering application. The aim of the present study is to prepare bioactive kalsilite composite material for application in tissue attachment and sealing of the marginal gap between fixed prosthesis and tooth. Mechanochemical synthesis is used for the preparation of microfine kalsilite glass-ceramic. Low temperature frit and bioglass have been prepared using the traditional quench method. Thermal, microstructural and bioactive properties of the composite material have been examined. The feasibility of the kalsilite to be coated on the base commercial opaque as well as the bioactive behavior of the coated specimen has been confirmed. This study indicates that the prepared kalsilite-based composites show similar structural, morphological and bioactive behavior to that of commercial VITA VMK95 Dentin 1M2.

“…Fluorine‐containing glasses are used for a wide variety of purposes, among them bioglasses and bioglass ceramics, where fluoride release stimulates hydroxyapatite formation, which bonds to human bone due to similar phase structure . Fluorine is also introduced into ionomer glasses which are used for glass polyalkenoate dental cements, where fluorine atoms are added to lower the refractive index of the glass as well as to enable fluoride ion release from the set cement to prevent secondary caries .…”

Thirty glasses of composition (in equivalent percent) Ca 20-x Y x Si 50 Al 30 O 100-y-z N y F z , with x = 0, 10; y = 0, 10, 20 and z= 0, 1, 3, 5, 7 were prepared by melting and casting. All glasses were X-ray amorphous. Glass molar volumes decreased with nitrogen substitution for oxygen for all fluorine contents and, correspondingly, glass fractional compactness increased. Fluorine substitution of oxygen had virtually no effect on molar volume or fractional glass compactness for the three nitrogen contents tested. Young's modulus and microhardness were virtually unaffected by fluorine substitution for oxygen while nitrogen substitution for oxygen caused increases in these two properties. Glass transition temperature and dilatometric softening point values all decreased with increasing fluorine substitution levels, whilst increasing nitrogen substitution caused values for these thermal properties to increase. Correspondingly, the thermal expansion coefficient increased with fluorine and decreased with nitrogen substitution levels. Using property value differences between glasses containing fluorine and the corresponding glass containing 0 eq. % F enabled 24 data points to be used to determine the effect of fluorine on T g,dil and T DS . The trends were linear with a gradient for both properties of the order of -22ºC·(eq. % F) -1 . For the nitrogen effect, 20 data points were analysed for trend effects. As expected from earlier work, all trends had good linearity. Gradients were for T g,dil and T DS +2.5ºC·(eq. % N) -1 , which are fairly similar to previous results in oxynitride systems. All of the data collected and its analysis clearly shows that the substitution effects of fluorine for oxygen and nitrogen for oxygen are independent and additive with the fluorine substitution. The property trends of the glasses are discussed in terms of their implications for glass structure.
