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