Currently, polycarboxylate cements are mostly used for long-term temporary cementation. Zinc phosphate cements or polycarboxylate cements are still used for cementation of posts and crowns. They are generally supplied as a powder and a liquid and their physical properties are highly influenced by the mixing ratio of the components. 2019-05-20 · Polycarboxylate cement (also called zinc polyacrylate cement), is the first cementing system that arose as a result of the effort to obtain an adhesive cemented agent that could be firmly attached to the tooth structure.
