Zinc phosphate is formed from zinc phosphate cement and used in dentistry. Zinc phosphate
dental cement is one of the oldest and widely used cements, and is commonly used for luting
permanent metal restorations and as a base for dental restorations. Zinc phosphate cement is
used for cementation ofinlays, crowns, bridges, and orthodontic appliances and occasionally
as a temporary restoration. It is prepared by mixing zinc oxide and magnesium oxidepowders
with a liquid consisting principally of phosphoric acid, water, and buffers. It is the standard
cement to measure against. It has the longest track record of use in dentistry. It is still commonly
used; however, resin-modified glass ionomer cements are more convenient and stronger
when used in a dental setting.
