Porcelain-Fused-to-Zirconia

Our porcelain-fused-to-zirconia crown and bridge restorations are fabricated out of a solid zirconia substructure and porcelain layering. With strength and esthetics combined, PFZ restorations are excellent long-lasting solutions. It provides more room for veneers than other restorations, which adds to its esthetics.

Indications

A CAD/CAM substitute for traditional PFM, our porcelain-fused-to-zirconia can be used for anterior and posterior crowns, crowns over implants, and bridges of up to fourteen units.

  • Attachment cases
  • Cases with less than 1 mm clearance
  • Bruxism
  • Patients who have broken a PFM crown
  • 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.

  • 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)

If an adjustment is required on the ceramic, use a fine diamond with water and air to keep the crown cool. To contour the ceramic, polish with a pink rubber wheel and diamond polishing paste (Brasseler, Shofu, Vident).

Full-Contour Zirconia

Our full-contour zirconia restorations are metal-free and biocompatible. Fabricated by our highly skilled technicians, these restorations have the highest flexural strength of any ceramic restoration. An ideal solution for patients, these full-contour zirconia restorations are gentle on opposing dentition.

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 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.

IPS e.max®

IPS e.max® is an ideal restoration for patients looking for extreme esthetics due to its five levels of translucency. Fabricated out of lithium disilicate glass-ceramic as either a full-contour monolithic or cut-back and layered with porcelain, this restoration offers high customization. It has achieved long-term success as a clinically proven solution. These restorations are minimally invasive and have a flexural strength of up to 500 MPa. Additional impulse ingots are available for maximum flexibility.

Indications

IPS e.max is the premium lithium disilicate, glass-ceramic restoration. Combining lifelike materials and fracture resistant properties, IPS e.max is as durable as it is lifelike. The flexibility of IPS e.max makes it an excellent restorative method for anterior esthetics or posterior function.

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 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.

If adjustments are needed, use fine diamonds with water and light pressure. Always remove the crown when adjusting or bond/cement crown before adjustments are made.

Full Cast Crowns

This successful dental restoration has proven longevity. When properly cared for our full cast crowns can last an entire lifetime. Fabricated out of noble and high noble alloys our full casts provide strength, durability, and biocompatibility. They are also gentle on opposing dentition and are ideal for the posterior region where there is minimal room outside of the esthetic zone.

Indications

Full-cast gold crowns are indicated for crowns, veneers, inlays, onlays, and bridges.

Full-cast gold crowns are contraindicated for partials and implants.

Inlays and onlays can also be fabricated as a full-cast restoration. Feather-edge margin preparations are indicated for full-cast restorations, but any margin preparation may be used.

  • Panavia 21 (Must be tin plated if precious metal is used)
  • Glass ionomer cement (GC Fuji, GC America)
  • Zinc Phosphate Polycarboxylate Resin Ionomer cement (RelyX, 3M ESPE)

All castings are made with a metal alloy, be it non-precious, semi-precious or precious metals. Alloys are classified by their content.

  • Base – contents include non-precious, Chrome Cobalt or Titanium
  • Noble – consists of 25 percent precious alloy
  • High Noble – consists of 60 percent precious metal with at least 40 percent being gold

Alloy type refers to the hardness and/or softness of the material.

  • Type I – Extra soft
  • Type II – Soft
  • Type III– Hard
  • Type IV – Extra Hard (Rigid)
  • Non-Precious, Noble 20, White High Noble – Type IV – Very hard and rigid. These crowns are more difficult to adjust and re-polish than alloys with a high gold content.

Indications

Our PFMs can be used for crowns and bridges (up to fourteen units). PFMs can be manufactured to nonprecious, semiprecious, and yellow high noble copings and can be used in conjunction with cast partials and implants.

Contraindicated when the patient has a metal allergy or when the size of the tooth pulp is negligibly smaller, thus compromising the tooth preparation process. It is also contraindicated when the clinical tooth crown is very short and lacks the required stability including retention that is enough to provide the space for porcelain and metal.

The ideal preparation for PFMs is a chamfer margin preparation. If a porcelain labial margin is prescribed, then a shoulder margin preparation is required.

  • Panavia 21 – tin plated
  • Glass ionomer cement (GC Fuji, GC America)
  • Zinc Phosphate Polycarboxylate
  • Resin Ionomer cement (RelyX, 3M ESPE)

If an adjustment is required on the ceramic, use a fine diamond with water and air to keep the crown cool. To contour the ceramic, polish with a pink rubber wheel and diamond polishing paste (Brasseler, Shofu, Vident).
