Making of a Captek Crown
Overview of the Captek Fabrication Process

Step 2: P Application

The Captek P layer is built and fired.

Take the Captek P material and cut a strip that is roughly the mesial distal width of the die.

Cut the strip again in a 60%, 40% proportion. Take the larger piece and place it on the labial surface of the die. It should extend slightly up over the incisal edge and slightly below the margin.

Press the Captek P material in place with your thumb, using even firm pressure so it conforms to the shape of the die. Excessive pressure or pulling of the material will cause it to tear or break. Pick up the smaller piece of Captek P and place it on the lingual side of the die. Note that it should be placed on the die in a diamond shape with one corner pointing up. Place in place with your finger and adapt as before.

Take your knife and trim away any excess material that maybe overlapped from the two pieces you have applied. Fill in any voids with trimmings. Save remaining trimmings of Captek P to fill any voids later on or to make additions to the copings. Carefully trim around the margins by cutting excess material away from the die. In the case of a feather edged margin, Captek P must be cut at the margin with a knife at approximately a 90 degree angle and then adapted at the same angle to avoid making the material to thin and brittle. If the material at the margin becomes too thin or or there is some breakage, add more material in thin strips. The thickness of Captek P on the die. With the flat edge of the Captek tool smooth out all the seams so Captek P uniformly covers the die. When adapting, try to smooth the material in place without pushing or stretching or thinning in place. Gently press it into smooth coverage. Using the flat end of the adapting instrument shear away excess material from the margin, then adapt the material again making sure the margin is completely sealed. Remove any excess material from above the margin and smooth the material on the die. Any excess material that is below the margin should be left until after firing.

The crown is now ready for firing!!!!

Slower is more accurate. Many furnaces can handle the 80 C / 145 F temperature rate of increase without problem but some could not. Reducing the rate to 55 C / 100 F has certainly made it easier for the furnaces to achieve more stability at the high end. Remember to recalibrate the furnace with Captek Calibration Strips at this slower rate before making the adjustment. It is suggested to add another program with the updated values and run a test crown prior to switching completely.

Captek P
is the Platinum/ Palladium/Gold capillary structure. This internal reinforcing skeleton is what separates the Captek technology from any other dental alloy in the world. This layer is smoothened to the die and fired in an automatic porcelain furnace on the recommended Captek cycle.
