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 .
The traditional method for management of dental caries has evolved from the exclusive domain of techniques based on complete caries removal prior to tooth restoration. Norna Hall used pre-formed crowns and cemented over carious primary molars using a glass-ionomer luting cement, with no caries removal, tooth preparation, or local anaesthesia.
Atraumatic restorative treatment (ART) [1] is a method for cleaning out tooth decay (dental caries) from teeth using only hand instruments (dental hatchet and spoon-excavator) and placing a filling. It does not use rotary dental instruments ( dental drills ) to prepare the tooth and can be performed in settings with no access to dental equipment.
CaOH does, however, have significant disadvantages. The set cement has low compressive strength and cannot withstand or support condensation of a restoration. [14] [16] It is thus good practice to place a stronger separate lining material (e.g. glass ionomer or resin-modified glass ionomer) over CaOH before packing the final restorative ...
Structure of dental inlays and onlays. In dentistry, inlays and onlays are used to fill cavities, [1] and then cemented in place in the tooth. This is an alternative to a direct restoration, made out of composite, amalgam or glass ionomer, that is built up within the mouth.
Zinc phosphate was the very first dental cement to appear on the dental marketplace and is seen as the “standard” for other dental cements to be compared to. The many uses of this cement include permanent cementation of crowns, orthodontic appliances, intraoral splints, inlays, post systems, and fixed partial dentures.
There are two major purposes of luting agents in dentistry – to secure a cast restoration in fixed prosthodontics (e.g. for use of retaining of an inlay, crowns, or bridges), and to keep orthodontic bands and appliances in situ. In a complex restoration procedure, the selection of an appropriate luting agent is crucial to its long-term ...
There are numerous types of precision attachments (also known as combined restorations) to aid removable prosthetic attachment to teeth, including magnets, clips, hooks, and implants which may themselves be seen as a form of dental restoration. The CEREC method is a chairside CAD/CAM restorative procedure. An optical impression of the prepared ...
