INspire™ UT

INspire™ HS

INspire™ UT

Our INspire™ Ultra-Translucent is ideal for both anterior and posterior units, including up to 3-unit anterior or posterior bridges, and in some cases veneers. It is fabricated to provide smooth shade transitions, which mimic the appearance of natural tooth enamel, dentin, and cervical shades. Since the color progression is natural and undisrupted, there are no abrupt shade edges. Tooth-like preshading provides an efficient and economical process that eliminates the need for any staining procedures. It has a high bending strength of up to 850 MPa, which is comparable to alternative all-ceramic restorations. This zirconia can match all 16 VITA® Classical Shades. For optimal esthetics, please provide the stump shade with each INspire™ UT case.

Additional Information About INspire™

Our INspire line is suitable for any restoration in which traditional monolithic crowns are traditionally indicated. INspire is preshaded, featuring four layers of chroma from sulcus to incisal to mimic natural enamel. Durable enough to resist chipping or fracturing, it’s gentle enough on opposing dentition to make it a standby material for patients with bruxism. Designed by our CAD/CAM specialists and fabricated on five-axis mills, INspire restorations feature finely detailed occlusal anatomy.

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.

Contraindications

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.

Preparation

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.

Cementation

Full-contour zirconia may be cemented using a resin reinforced glass ionomer such as RelyX Luting cement. When a greater bond is needed do 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.

Tech Notes

Solid zirconia requires a cast gold type preparation. If adjustments are needed, use zirconia specific diamonds and rubber wheels polishing with diamond paste.
