AZ Primer is a priming agent designed to treat the surfaces of alumina-based or zirconia-based restorations to enhance bond to resin materials. AZ Primer can be used intraorally and extraorally. A unique innovation specifically created to provide a stable and dependable bond with all-ceramic zirconia and alumina restorations. The novel 6-MPHA monomers in Shofu AZ Primer secure permanent anchorage to the all ceramic bonding surface and ensure long-term clinical success. The 6-MHPA monomer, specially adapted for high-performance porcelains, anchors itself permanently to the restoration and thus is superior to other bonding systems, especially ?ll-in-one?products. The primer can be applied intraorally and always ensures excellent bond strengths when used in combination with the light-cured opaque pastes of the SHOFU Universal Opaque system. INDICATIONS FOR USE Bonding resin to alumina or zirconia restorations Cementation of restoration with adhesive resin cement Repair of fractured restorations using composite resin
