MeSH: Zinc Phosphate Cement - Finto

SVENSK PATENTTIDNING

Highly charged polycarboxylate crown ethers are effective, but relatively unselective, cation complexing agents for a range of cations. The complexes are stable to pH 3 and the ligands can be used Occasionally useful to retain an unretentive provisional crown. Zinc polycarboxylate (or zinc polyacrylate) has a relatively long history as a luting cement. Unlike zinc phosphate, polycarboxylate 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. During this post we will analyze its chemical composition, as well as its characteristics and use.

Properties of Zinc Polycarboxylate Cement: Copings were cemented with eugenol-free zinc oxide (Freegenol), zinc phosphate (Harvard), glass ionomer (Ketac Cem), polycarboxylate (Durelon) and so-called self-adhesive resin (RelyX Unicem) cement. Cement was applied in a thin film band of 1 or 3 mm to the cervical margin of the inner surface of the copings, respectively.

Zinc polycarboxylate also may be used as a stronger provisional cement for the transitional prosthesis when zinc oxide eugenol appears insufficient. Crown ethers derived from tartaric acid present a number of interesting features as receptor frameworks and offer a possibility of enhanced metal cation binding due to favorable electrostatic interactions. The synthesis of polycarboxylate crown ethers from tartaric acid is achieved by simple Williamson ether synthesis using thallous ethoxide or sodium hydride as base. Stability constants for Description. Polycarboxylate cement is used as a cementing medium of cast alloy and porcelain restorations. In addition, polycarboxylate dental cement can be used as a cavity liner, as a dental base liner under metallic restorations, or as a temporary restorative material. We also carry a hybrid luting cement.
