N&V Tips
Helpful tips for pressable ceramics

Pressable ceramics have become a top choice of many clinicians because of their ability to create such esthetically pleasing restorations. With Universal Z4 Investment and Disposable Plungers being great choices for improving pressing results, we've had an opportunity to help many dental laboratories troubleshoot different types of problems.

Many of the newer all-ceramic materials can be tricky to use at first and users must often make adjustments to "dial in" their results. With that in mind we thought we would share a few of the problems and solutions we commonly see… Soon

Question: After sandblasting, I have a couple of edgy rough spots on the casting

Answer: In this case it is perhaps not bad to have a look at your wax pattern under microscope before investing. Sometimes one is surprised to see how many dust particles are on the surface of the pattern. It may be gypsum dust, grains of sand blasting material or any other scrap sticking to the wax. By using Z4, a very fine flowing investment that reproduces every detail, the scrap will be perfectly cast and visible on the surface of the casting. Cleaning the wax before investing with dry air or water may be the solution here. Better still is to work in a clean environment for waxing up. Ideal is to not wax up on the same spot as where you finish the metal!

Question: The casting comes a bit rough out of the investment and I have a hard time sand blasting the metal

Answer: This is an indication of overheated metal. The metal may not be burned but it is overheated. The best way to check if the metal was cast at the right time is to just pass your finger over the button or cone of the casting. If the edge feels sharp, the metal was heated too much. The edge should be rounded as a clear indication of the right casting temperature. As a result of casting at the right temperature the castings will come clean of investment with just some oxidizing on the metal depending on the kind of metal used.
