Artistic EZ is an esthetic alternative to high-strength Zirconia, PFZ, PFM or full cast restorations. This esthetic solution is ideal for anterior restorations requiring extra durability such as crowns under partials or screw-retained implant crowns. Artistic EZ exhibits an average flexural strength of 765 MPa and is exclusively available from Artistic Dental Laboratories. The chip-proof durability of these restorations makes them ideal for bruxers who have broken natural teeth or previous PFZ/PFM restorations. Artistic EZ restorations are also ideal for patients lacking the preparation space for a PFZ/PFM and come with a 5-year replacement-free warranty.Send a Case Download Rx
Full-contour zirconia is so versatile, it can be used in almost any situation from singles, bridges with any combination of abutments and pontics, inlay bridges and screw-retained implants. Also an esthetic alternative to a PFM with metal occlusion due to limited space.
When esthetic expectations are high and it is important that the restorations match surrounding natural dentition or other existing restorations. If bonding is necessary to retain the restoration, bond strength is weaker and less predictable than other ceramics.
Shoulder preparation not needed. A mild chamfer or a feather-edge margin is good. 1mm buccal, lingual, and occlusal reduction is ideal, but can go to .5mm in some areas when reduction is limited. Minimum occlusal reduction of 0.5 mm; 1 mm is ideal. Adjustments and polishing: Adjust full-contour zirconia crowns and bridges using water and air spray to keep the restoration cool and to avoid microfractures with a fine grit diamond. If using air only, use the lightest touch possible when making adjustments. A football-shaped bur is the most effective for occlusal and lingual surfaces (on anterior teeth); a tapered bur is the ideal choice for buccal and lingual surfaces. Polish full-contour zirconia restorations with the porcelain polishing system of your choice.
It is recommended that full-contour zirconia be cemented using a zirconia primer like Z-Prime™ from Bisco or Clearfil Ceramic Primer from Kuraray. Alternatively, a resin reinforced glass ionomer such as RelyX™ Luting cement can also be used. When a greater bond is needed due to the lack of a retentive preparation, use a resin cement like RelyX™ Unicam or RelyX™ Ultimate. Before cementing all full-contour zirconia crowns, the interior surface of the crown needs to be cleaned with Ivoclean (Ivoclar Vivadent - Amherst, NY). This is critical in assuring maximum bond strength.
Solid zirconia requires a cast gold type preparation. If adjustments are needed, use zirconia specific diamonds and rubber wheels polishing with diamond paste.
