TECHNICAL 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).

INDICATIONS / CONTRAINDICATIONS
Captek can be used for all single-unit crowns & 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.
Captek should not be used when a tooth preparation is not built back up to preparation form or there is over 3 mm 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. For 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. For 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.
