Glass Ionomer Cement (GIC) in Dentistry | Dental Cements

16.06.2021· Glass ionomer cement (GIC) is the restorative material used for restoring carious teeth. It is an adhesive and tooth coloured restorative material. It is highly used in the restoration of carious teeth involving the anterior teeth due to its high esthetic in nature compared to amalgam restoration. It also possesses an anti-cariogenic property that prevents secondary caries. It is called glass

Prospective observation of a new bioactive luting cement

Materials and methods: The cement used in this study is a new formulation class, a hybrid material comprising calcium aluminate and glass ionomer. Thirty-eight crowns and fixed partial denture (FPD) abutments were cemented in 17 patients. Thirty-one of the abutment teeth were vital, 7 nonvital. Six reconstructions were FPDs comprising 14 abutment teeth (12 vital/2 …

Glass Ionomer Cement - an overview | ScienceDirect Topics

Glass ionomer cements are classified as either conventional glass ionomer cements, which are water-based without any resin, or resin-modified glass ionomer, which has about 10% resin added to improve physical properties. Both types of glass ionomer cements are adhesive to enamel and dentin via ionic bonding of the glass ionomer to the calcium and phosphate ions …
