All Ceramics

IPS e.max press is indicated for full anterior or posterior crowns, veneers, inlays, onlays,as well as three-unit bridges having only one pontic with the second bicuspid as the most distal abutment.

Bridges which include molars, Maryland style bridges and bridges which have a short vertical height that does not allow for adequate connector height.

Anterior full-coverage crowns require a chamfer or shoulder margin. A circular shoulder is prepared with rounded inner edges or a chamfer at an angle of 10-30°: the width of the shoulder/chamfer is approx. 1 mm. Facial reduction is 1.5 – 2 mm; 1 – 1.5 mm lingual contact clearance. Incisal reduction is 1.5 – 2 mm with rounded internal line angles, and an incisal edge at least 1mm wide to permit optimum milling of the incisal edge during CAD/CAM processing.
Posterior full-coverage crown requires a chamfer or shoulder margin. A circular shoulder is prepared with rounded inner edges or a chamfer at an angle of 10-30°: the width of the shoulder/chamfer is approx. 1 mm. Occlusal reduction is 1.5 – 2 mm: axial reduction (buccal, lingual and interproximal) is 1.5 mm with rounded internal line angles.

IPS e.max layered – can be either cemented using a resin reinforced glass ionimer such as Relyx Luting cement. Or bonded using a resin cement, when extra strength is needed due to lack of retention on the prep, use a resin cement such as Relyx Unicem or Relyx Ultimate.

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 include:
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 champfer 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 micro-fractures 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 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 N.Y.). This is critical in assuring maximum bond strength.

A CAD/CAM substitute for traditional PFM, our porcelain fused to zirconia can be layered for the facial zone, and is preferred for the high esthetic anterior region or regions were esthetics are a concern for the patient.

Cases with less than 1 mm clearance
Cases that require bonding

The ideal preparation for PFZs is a chamfer margin preparation. If a porcelain labial margin is prescribed, then a shoulder margin preparation is required.
Feather-edge margin preparations are indicated for full-cast restorations.

Resin Ionomer cement (RelyX or RelyX Unicem, 3M ESPE)
Maxcem Elite (Kerr)
Panavia F 2.0 (Kuraray) -ideal for short, tapered preparations
Glass ionomer cement (GC Fuji, GC America)

A highly versatile zirconia, Katana UTML is indicated for Ideal for anterior crowns and veneers, inlays/onlays and posterior single crowns.

If the patient is hypersensitive to zirconia or any other components, Katana UTML should not be used.
Contraindicated forms include:

• “J” margin
• Deep shoulder
• Knife edge
• Undercuts
• Rough margin
• Groove
• Paralled axis
• Sharp incisal top
• Height difference (anterior)
