glass ionomer adhesive material

[Application]
Bonding casting, ceramic restorations, appliances with ring; cavity lining,
 Bottom, filling, especially for wedge-shaped defect.
This material is easy to Apex Locator absorb water, can be eroded and dissolved. Further, after the reaction of a polycarboxylic acid aluminum,
Cement before they become hard, this process takes at least 30min.
Tooth surface should be clean and free of saliva, prosthesis surface should be free of impurities and pollution.
Curing process should pay attention to dehydration and water pollution are prohibited. Prosthesis
Edge or the edge of backfill applications varnish or light-curing sealant protection
Glass ionomer and zinc polycarboxylate like and enamel, dentin,
And alloy bonding occurs. In vitro and in vivo tests show that
 Bond strength by the dental instruments surface properties.

[Disadvantages]
Benefits - Easy mixing, high strength and rigidity, the release of fluoride. Acid-soluble,
Chemical bonding properties, transparency.
Disadvantages - slow solidification, solidification of early water-sensitive, adhesive properties is not exact,
Cut X-ray transmission, curing light  the initial pulp stimulation.
