Dental composite resin. As with other composite materials, a dental composite typically consists of a resin -based oligomer matrix, such as a bisphenol A-glycidyl methacrylate (BISGMA), urethane dimethacrylate (UDMA) or semi-crystalline polyceram (PEX), and an inorganic filler such as silicon dioxide (silica).
Glass ionomer cement. A glass ionomer cement (GIC) is a dental restorative material used in dentistry as a filling material and luting cement, [1] including for orthodontic bracket attachment. [2] Glass-ionomer cements are based on the reaction of silicate glass-powder (calciumaluminofluorosilicate glass [3]) and polyacrylic acid, an ionomer.
Dental compomers, also known as polyacid-modified resin composite, are used in dentistry as a filling material. They were introduced in the early 1990s as a hybrid of two other dental materials, dental composites and glass ionomer cement, in an effort to combine their desirable properties: aesthetics for dental composites (they are white and ...
Dental restoration, dental fillings, or simply fillings are treatments used to restore the function, integrity, and morphology of missing tooth structure resulting from caries or external trauma as well as to the replacement of such structure supported by dental implants. [1] They are of two broad types— direct and indirect —and are further ...
Dental cement. Dental cements have a wide range of dental and orthodontic applications. Common uses include temporary restoration of teeth, cavity linings to provide pulpal protection, sedation or insulation and cementing fixed prosthodontic appliances. [1] Recent uses of dental cement also include two-photon calcium imaging of neuronal ...
Impression materials are designed to be liquid or semi-solid when first mixed, then set hard in a few minutes, leaving imprints of oral structures. Common dental impression materials include sodium alginate, polyether and silicones. Historically, plaster of Paris, zinc oxide eugenol and agar were used.
Light curing of a dental filling material. A dental curing light is a piece of dental equipment that is used for polymerization of light-cure resin-based composites. [ 1 ] It can be used on several different dental materials that are curable by light. The light used falls under the visible blue light spectrum.
Bis-GMA. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Bis-GMA (bisphenol A-glycidyl methacrylate) is a resin commonly used in dental composite, dental sealants. [1][2] and dental cement. It is the diester derived from methacrylic acid and the bisphenol A diglycidyl ether.
