Full-Contour Zirconia

Full-Contour Zirconia

Nakanishi offers three high-quality full-contour zirconia restorations that are ideal for both posterior and anterior cases. After years of exhaustive research and development, we have selected three zirconia solutions that offer superior results. Our team is made of Certified Dental Technicians and industry experts who carefully craft every zirconia crown and bridge to perfectly meet the needs of each patient. We utilize superior zirconia materials that ensure seamless esthetics and minimal wear to opposing dentition.

High Strength Zirconia

Our base zirconia offers high esthetics and extreme strength.

Ultra-Translucent Zirconia

Our ultra-translucent zirconia ensures beautiful and vital esthetics. Our technicians fabricate our UT zirconia restorations to provide ideal anatomy and fit for every patient.

Multi-Layered Zirconia

When a case requires exceptional beauty and multi-layered esthetics, our ML zirconia is the ideal selection. It provides seamless color gradation and vital fluorescence. Our ML zirconia also offers a high flexural strength that ensures a long-lasting solution.

Indications

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, Maryland type 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.

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.

Full-contour zirconia may be cemented using a resin reinforced glass ionomer such as RelyX Luting cement. When a greater bond is needed due to the lack of a retentive preparation, use 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.
