TECHNICAL NOTES
What is the CTE for Prismatik ThinPress?
The CTE for Prismatik ThinPress is 13.
What is the flexural strength for Prismatik ThinPress?
The flexural strength is 167 MPa.
What is the ingot size for Prismatik ThinPress?
2 gram ingots; each ingot is 11 mm in diameter.
What is the most translucent ingot I can use?
TP12 is our most translucent Prismatik ThinPress ingot. It is used mostly for shade adjustable veneers, inlays, onlays, and 1 mm or thicker full coverage all-ceramic crowns.
What ingot offers translucency and matches shades A1, A2, B1 and B2?
TP8 matches shades A1, A2, B1 and B2. It is the most popular ingot used on our production floor, as well as the most purchased by other labs.
How many units can you press using only one ingot?
Up to 0.6 g of wax for one ingot (waxed, including sprue).
What size plunger is used for these 2-gram ingots?
The plunger is 12 mm in diameter. It is also disposable.
What investment material can be used to invest the waxed units?
You can use any all-ceramic investment. At Glidewell, we use Microstar® HS™ investment.
What is the water/powder ratio for investment material?
Always follow the investment manufacturer’s instruction for accurate investing.
What is the burnout temperature?
Follow the investment manufacturer’s instruction for burnout. (Using Microstar HS, we burnout at 1652°F for 45 minutes per ring, adding 10 minutes for each additional ring.)
What happens if the investment ring is in burnout oven for a longer time than instructed?
It may result in brittle investment and possibly cracking of the ring during pressing.
What happens if the investment ring is removed from the burnout oven before the instructed time?
It may result in cold casting or cold pressing, not allowing the molten ceramic to reach all the proper areas.
Do Prismatik ThinPress ingots or disposable plungers need to be placed in the burnout oven?
No, do not place the ingots or the plungers in the burnout oven. This will retard the flow ability of the molten porcelain ingots during pressing. Place the ceramic ingots in the investment after burnout is complete and place in the pressing oven.
Can Universal Stain and Glaze be used over Prismatik ThinPress ingots?
Yes.
Which Opal Incisal Layering Powders will work better with most ingots?
The Blue/White is most used. We only have three powders available, but they can be mixed with each other to achieve the translucency desired.
When or why would correction powders be needed?
Correction powders are designed to match the ingots exactly, in case minor corrections are necessary, such as adding contacts, modifying contour, repairing voids and margin.
