Advantages And Disadvantages Of Glass Ionomer Cement. Glass ionomer cements GICs can have a range of compositions but the chief constituents are alumina silica and calcium. Glass ionomer is usually used for small fillings cementing metal and porcelainmetal crowns liners and temporary restorations.
Here is a description about the zirconia based or we can say zirconia reinforced glass ionomer cementit is used for the permanent restoration of the cavitie. Thus fracture force of a bonded system is measured for a particular method of load application and hence should be interpreted as bond strength with caution13 Failure modes of Glass ionomer cement 1213 and Biodentine 1415 to dentine were largely cohesive within the cement rather than at the interface. Early contamination with water reduces translucency.
The unique properties of GIC include direct adhesion to tooth and base metals 1 anticariogenic properties 2.
It is tooth-colored and varies in translucency. These cements are more promising for cementing indirect restorations due to the incorporation of a light-activated component. They had long hardening times and were very susceptible to breakdown or fracture if they became too wet or too dry during the extended setting reaction. This video of Aspire32 explains the Resin Modified Glass Ionomer cement also called Light cured Glass Ionomer cement for easy dentistry.
