Anon. asks:
What does it mean when a veneer is ‘pressed’? How does this differ from other kinds of veneer materials? In the past, when I did veneers I just sent the impressions to the lab and they sent back porcelain veneers. I never knew there were choices of materials to use. I have never used the veneers made out of composite material. I have had great success with veneers over the years. But I want to learn about new materials which may even be better. Any comments?

    Hi:
    A pressed ceramic means that the lab makes a pattern of the venner and then uses a similar procedure to the lost wax for casting. after that they put the mold in a machine that heats up a porcelain ingot (a little cube usually made of leucite ceramic) and after its hot enough it gets prssed into the mold by a pushing rod at a continuous high pressur(hence pressed ceramic) and you get a very similar thing to a casted metal , normally its single colour so it needs colour retoching and translucent placement if needed. That is pretty much it.

    For years we only did layered veneers known as refractory or foil veneers. A while back companies like Ivoclar and several others came out with a pressable ceramic that seemed to take over the veneer industry. So today you can have a veneers pressed and stained, pressed and layered,refractory or foil ( both also known as feldspathic to) veneers as well. Labs like the pressed veneers because it is not as time consuming as the refractory veneer method. The materials are basically the same about the only differance you will see is based on the lab doing the case. Some believe refractory can be more translucent which is probably true. In the right hands both materials can give a great result.
