Porcelain Fused to Captek

Ceramic is fused to 22kt Captek gold, producing esthetics that rival all-ceramic restorations. Captek yields impressively high strength and density, which makes it ideal for long-span bridges and implants.

Indications

Captek is indicated for single-unit crowns and bridges with up to 2 pontics. It may also be prescribed for cantilever bridges, bruxers, and full-arch cases. It is highly esthetic and can be used when reduction of the tooth may be limited.

Benefits for the Patient

  • The 88% gold Captek coping provides a warm lifelike appearance, eliminating dark oxides at the gingival margin. This is because Captek is fired in an oven unlike traditional cast copings.
  • This high gold content also offers high biocompatibility and corrosion resistance because of its unique composite metal alloy construction.
  • Captek ceramic provides a smooth dense surface that resists heavy plaque accumulation and causes less wear on natural opposing dentition.

Prep Requirements

  • 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. For anterior: 2.0 mm incisal reduction, 1.5 mm middle third reduction, ensuring preparation is cut into three planes and that labial and lingual walls are convergent. For posterior: 2.0 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.
