Traditional Fixed

Arcari’s conventional restorations are fabricated using the most advanced materials and techniques available on the market today. Utilizing rapid wax prototyping combined with CAD/CAM technology and over 30 years in the dental lab profession, our Certified Dental Technicians provide a high-quality restoration with excellent fit, function and esthetics.

In porcelain fused to metal restorations, porcelain is typically fused to semi-precious, white or yellow high noble alloy. An ideal restoration for your most demanding patients.

Arcari traditional PFM’s are fabricated using the most advanced materials available. With over 40 years in the dental lab profession, Arcari Certified Dental Technicians have substantial expertise in many techniques. This ensures a high-quality restoration critically focused on both function and esthetics.

Special attention is taken in trimming the dies, and your case is quality-controlled every step of the way from model work, wax, metal to ceramic-finished crown or bridge.

Though Arcari offers a full range of alloys for the creation of esthetic restorations, gold remains the perfect choice for many leading clinicians due to its longevity and functional success.

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).

Ceramic fused to a 22k Captek substructure produces esthetics that rival all ceramic restorations. Captek has been proven to reduce harmful bacteria and plaque deposits by as much as 71%, resulting in incredible compatibility with surrounding tissue. In fact, Captek™ has been shown to exhibit less bacterial accumulation than natural teeth in the same mouth!

The Captek™ substructure is not cast, but pressed utilizing the APP SYSTEM. This allows Arcari technicians to create each coping in a precise and consistent manner. Captek provides a warm, lifelike appearance at the gingival margin.

Captek™ from Arcari will give your patients a natural, beautiful smile with greater confidence.

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).

Codes

  • D2750 Single Crown PFG
  • D6999 Captek Inlays

PD Attachment

This is our economical means of fabricating semi-precision particles and precision rests using pre-made plastic precision male & female dowels that are interchangeable.

ERA Attachment

This is one of the most popular dental attachments prescribed today due to its proven performance and versatility of use. Our ERA attachments consist of a metal female component, which is fixed intraorally, and a replaceable, high density nylon male anchored in the denture base.

Surveyed Crown

Our prosthetic crown yields more ideal contours than natural teeth and is used to support and retain extracoronal, clasp-type removable partial dentures.

Gold continues to be the preferred choice for many leading clinicians. This is due to its longevity, functional success, biocompatibility and exceptional fit. The Arcari laboratory full cast team is trained in the five step quality control process: Contacts, Occlusion, Margins, Anatomy and Finish.

Gold crowns are resistant to oxidation, corrosion and plaque accumulation. Full cast restorations are fabricated from alloys specially formulated for all gold crowns, bridges, inlays and onlays. These alloys deliver the biocompatibility and long-term durability for which gold is historically known.

All Arcari full cast yellow gold alloys meet ADA specifications for “high noble” and exhibit a beautiful, rich gold color.

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.
