The high strength and physical integrity of zirconia and alumina metal oxide indirect restorations have rapidly increased their popularity. These crowns and bridges are compatible with conventional preparation and impression and scanning and milling techniques. Existing cementation technologies, however, were not compatible with the metal oxide ceramic surfaces; they functioned merely as luting (rather than adhesive) agents. Z-PRIME Plus, a single-component priming agent indicated as a surface treatment for zirconia and alumina, metals, alloys, composites, and endodontic posts, enhances adhesion between indirect restorative materials and composite resin cements. It has high bond strengths (both self-cure and light-cure) and bonds chemically to zirconia, decreasing the need for excessive tooth preparation. It is ideal for short crown preparations as well as zirconia-based Maryland bridges. The convenient, single-bottle delivery offers easy dispensing and eliminates any possibility of clinical error.
