Glass ionomer cement is primarily used in the prevention of dental caries. This dental material has good adhesive bond properties to tooth structure, [8] allowing it to form a tight seal between the internal structures of the tooth and the surrounding environment. Dental caries are caused by bacterial production of acid during their metabolic ...
Compomers are resin-based materials like dental composites, and the components are largely the same.. The setting reaction is similarly a polymerisation process of resin monomers (e.g. urethane dimethacrylate) which have been modified by polyacid groups, and is induced by free radicals released from a photoinitiator such as camphorquinone.
Radiopacity in dental materials is an important property that allows for distinguishing restorations from teeth and surrounding structures, assessing the absorption of materials into bone structure, and detecting cement dissolution or other failures that could cause harm to the patient.
Dental composites. Glass ionomer cement - composite resin spectrum of restorative materials used in dentistry. Towards the GIC end of the spectrum, there is increasing fluoride release and increasing acid-base content; towards the composite resin end of the spectrum, there is increasing light cure percentage and increased flexural strength.
Good thermal insulation properties as a liner under metal restorations; Opacity – for diagnostic purposes on radiographs. Low film thickness (maximum 25 microns acc. to ISO 9917-1). Low allergy potential; Low shrinkage; Retention – if an adhesive bond occurs between the cement and the restorative material, retention is greatly enhanced.
Both glass ionomer (GI) and resin-modified glass ionomer (RMGIC) have been widely used as a lining or base material for deep cavities where pulp is in close proximity. This is due to their superior properties of good biocompatibility and adhesive nature, providing coronal seal to prevent bacteria infiltration.
Dental porcelain (also known as dental ceramic) is a dental material used by dental technicians to create biocompatible lifelike dental restorations, such as crowns, bridges, and veneers. Evidence suggests they are an effective material as they are biocompatible, aesthetic, insoluble and have a hardness of 7 on the Mohs scale.
Dental cermets, or silver cermets, are a type of restorative material dentists use to fill tooth cavities. Silver cermets were created to improve the wear resistance and hardness of another type of filling material, glass ionomer cements, through the addition of silver. While the incorporation of silver achieved this, cermets have poorer ...
