Zinc phosphate cement is without any adhesive properties and is used as a luting agent. It is always referred to as a cement and is used for the attachment of indirect restorations and appliances to the teeth and for the cementation of inlays, crowns, bridges, facings, and orthodontic brackets.
Zinc Phosphate is the oldest of the cementation agents and thus the one with the longest track record (introduced in 1878). It serves as a standard by which newer systems can be compared. It consists of powder and liguid in two separate bottles. The main ingredients of the powder are zinc oxide and magnesium oxide. The liquid contains phosphoric acid, distilled water, alumina hydrate, and zinc oxide. Zinc phosphate cement is without any adhesive properties and is used as a luting agent. It is always referred to as a cement and is used for the attachment of indirect restorations and appliances to the teeth and for the cementation of inlays, crowns, bridges, facings, and orthodontic brackets.
I am sorry, but the provided text is a 510(k) clearance letter for a Zinc Phosphate Cement and contains no information about acceptance criteria or a study proving that a device meets those criteria. The document is a regulatory approval letter, not a scientific study report. Therefore, I cannot extract the requested information.
