Artisan Z High-Translucent Zirconia

The next generation of full-contour zirconia, Artisan Z is the ideal crossover between strength and esthetics. Its 769 MPa flexural strength ensures it’s durable enough for any indication. Its translucency rivals that of lithium disilicate restorations, making it esthetic enough for anterior restorations.

Indications

The next generation of full-contour zirconia, Artisan Z is the ideal crossover between strength and esthetics. Its 769 MPa flexural strength ensures it’s durable enough for any indication. Its translucency rivals that of lithium disilicate restorations, making it esthetic enough for anterior restorations.

Contraindications

Bridges over three units, Maryland-style bridges and restorations with dark prep shades

Cementation

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 Zirconia crowns, the interior serface of the corwn needs to be cleaned with Ivoclean (Ivoclar Vivadent;Amherst N.Y.). 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.

HDS has zirconia adjustment kits available.

IPS E.max®

For the ultimate metal-free restoration, Harrison Dental Studio is proud to offer IPS e.max. The superior strength and esthetics of IPS e.max, a sturdy glass-ceramic, will fulfill your patients’ needs for both functionality and appearance. With Harrison Dental Studio and IPS e.max, you get personalized, functional and highly esthetic restorations.

IPS e.max®

E.max® Press

IPS e.max is a monolithic lithium disilacate material with a flexural strength of over 400 MPa. Dies are scanned then cad designed. Wax ups are milled on a 4 axis mill, then pressed for an exact fit.

Layered eMax®

IPS e.max® Layered

IPS e.max layered has all the same characteristics and benefits as an e.max, but the facial is layered with a nano-fluorapatite ceramic for added translucency and internal staining and characterization. E.max press and E.max layered may also be combined together for the same bridgework.

Indications

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.

Contraindications

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

Preparation

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.

Cementation

e.max press and emax 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.

e.max Veneers - use a total etchant like Relyx Veneer or Relyx Ultimate.

e.max Inlays/Onlays—Should also be bonded with resin cement like Relyx Ultimate or Relyx Unicem.

Tech Notes

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.

 

BruxZir®

A full-contour zirconia formulated for strength, BruxZir® is still gentler on opposing dentition than porcelain restorations. One of the most frequently prescribed all-ceramic restorations on the market, BruxZir provides the perfect solution for anterior restorations.

BruxZir

BruxZir®

BruxZir full contour is a monolithic solid zirconia material having a flexural strength of up to 1400 MPa. Using CAD/CAM technology it is designed and milled using a 4 axis mill, then sintered to over 1500°C.

BruxZir Layered

BruxZir® Layered

Bruxzir layered is similar to Bruxzir full contour but is facially cut back and layered with a fluorapatite ceramic for added translucency and characterization. Bruxzir full contour and Bruxzir layered may also be combined together on the same bridgework.

Indications

BruxZir Logo

Bruxzir 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.

Preparation

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 BruxZir 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 BruxZir restorations with the porcelain polishing system of your choice.

Cementation

Bruxzir 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 Bruxzir zirconia crowns, the interior serface of the corwn needs to be cleaned with Ivoclean (Ivoclar Vivadent;Amherst N.Y.). This is critical in assuring maximum bond strength.

PFM

PFM

Harrison Dental Studio offers traditional, high-quality PFM services. We use the Ceramco® 3 porcelain system, and our PFMs are available in high noble, high noble yellow and noble alloys.

Preparation

The ideal preparation for PFMs 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.

Cementation

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

Tech Notes

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 Cast Crown

Full-Cast Crowns

Harrison’s gold restorations are completely bio-compatible. Your patients will enjoy the comfort and function of these crowns, available in high-noble to semi-precious gold.

Preparation

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.

Cementation

  • Panavia 21 (Must be tinplated if precious metal is used)
  • Glass ionomer cement (GC Fuji, GC America)

Tech Notes

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.

Full Cast 40 – Type III – Yellow high noble alloy. Brand name currently used is Argenco 40 HN.

Full Cast 52 HN – Type III – Yellow high noble alloy. Brand name currently used is Argenco 52.

Full Cast 75- Type III – Yellow high noble and is an upgrade from full cast 52. The gold is slightly more yellow in color. Brand name currently used Argenco 75.
