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.
If permanent restoration cannot be carried out immediately after tooth preparation, temporary restoration may be performed. The prepared tooth, ready for placement of restorative materials, is generally called a tooth preparation. Materials used may be gold, amalgam, dental composites, glass ionomer cement, or porcelain, among others.
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.
Dental cements have a wide range of dental and orthodontic applications. Common uses include temporary restoration of ... Glass ionomer cements have been used to ...
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.
Glass ionomer cements can be used with metal and metal-ceramic restorations provided they possess adequate retentive and resistance form. They are however, contraindicated for all-ceramic restorations that are low-strength. [9] It is also suitable for use in amalgam restorations, due to its ability to withstand amalgam condensation.
Dental lining materials are used during restorations of large cavities, and are placed between the remaining tooth structure and the restoration material. The purpose of this is to protect the dentinal tubules and the sensitive pulp , forming a barrier-like structure.
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 ...
