Captek™

Standard in-lab turn-time: 7 Days

With the strength and biocompatibility of traditional PFM, Captek™ restorations feature substructures crafted from proprietary blend of high-noble metals. This base better mimics natural pulp and dentin, allowing porcelain crowns a more natural, reflective surface. With highly reflective copings, Captek restorations also provide improved marginal esthetics should gingiva recede after seating.

Conventional Crowns

Indications

Captek can be used for all single unit crowns and bridges with up to 2 pontics. Captek can be used when reduction of the tooth may be limited. Captek can be used when periodontal health is a concern and when biocompatibility is a concern.

Contraindications

Captek should not be used when a tooth preparation is not built back up to preparation form or there is over 3 millimeters of clearance. Captek should not be used when adapting to a future or existing partial, or when a metal occlusal is prescribed.

Preparation

The ideal preparation for PFMs is a chamfer margin preparation. If a porcelain labial margin is prescribed, then a shoulder margin preparation of 1.25 mm is required.

Anterior: 2 mm incisal reduction, 1.5 mm middle third reduction, ensuring preparation is cut into three planes and that labial and lingual walls are convergent.

Posterior: 2 mm occlusal reduction; 1.5 mm middle third reduction; 1.25 mm gingival reduction on the buccal; buccal and lingual walls must be convergent. Feather-edge margin preparations are indicated for full-cast restorations.

Cementation

  • Panavia 21 (Must be tinplated)
  • Glass ionomer cement (GC Fuji, GC America)
  • Zinc Phosphate
  • Polycarboxylate
  • Resin Ionomer cement (RelyX, 3M ESPE)

Tech Notes

We use capillary attraction forces to create the Captek copings. It is the only way to combine the hard, thermally stable particles of platinum/palladium and the resilient, vibration absorbing, esthetic enhancing particles of the high purity gold without sacrificing strength. If we were to take gold, platinum and palladium in similar amounts and melt them together similar to traditional casting methods we would have a soft, weak, silver unstable coping. Just like the way the water and sponge exist, the gold and platinum/palladium exist. We have created an “alloy composite”. Captek is strong (in a sense reinforced), high gold and high temperature stable for accurate margins during porcelain firings.

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 Gold

Standard in-lab turn-time: 7 Days

Full cast restorations remain an industry standard for a simple reason: No other restoration functions as well. Our 54% and 78% percent alloys resist bacteria and they’re the most biocompatible restorations available. Gold alloys are also the gentlest material on opposing dentition, making it a perfect material for bruxers.

Conventional Crowns

Indications

Full-cast restorations are indicated for single crowns as well as bridges anywhere in the mouth.

Inlays and onlays can also be fabricated as a full-cast restoration.

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)
  • Zinc Phosphate Polycarboxylate Resin Ionomer cement (RelyX, 3M ESPE)

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.

PFM

Standard in-lab turn-time: 7 Days

The original cosmetic restoration, porcelain fused to metal restorations offer a cost-efficient way for patients to receive lifelike crowns. With ceramic crowns offering esthetics with translucency and shading that approach that of natural dentin reinforced by metal copings, PFM restorations are as versatile as they are sturdy.

Conventional Crowns

Indications

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

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).
