Veneers can be fabricated using 3 different techniques:

  1. Refractory die technique
  2. Platinum foil technique
  3. Press technique

Refractory die technique

When using the refractory die technique very high aesthetics can be achieved by using feldspatic porcelains. It involve stratification techniques where internal color build up and layering of different layers of dentin, enamels and internal colors are placed by an experienced technician to achieve an excellent result. The technique is cumbersome and once the refractory material was removed no corrections can be made.

Platinum foil technique

This technique requires the use of a very thin layer of platinum foil to be folded over the prepared die. There is a specific way to fold he foil so it keeps its shape and Vitalab use theTanaka press to ensure the close adaptation of the foil to the die for accuracy. The stratification technique is the same as with the refractory die technique. Once the foil is removed no modifications that require additional firings can be made since it will distort the porcelain.

Press technique

The press technique is much more forgiving as far as changes are concerned. The technique requires a wax-up of the restoration and pressing with a monochromatic pressing material that usually have the desired basic shade. The veneer is then cut back labial/incisally and layered with porcelain. One of the biggest advantages is that very thin “no prep” veneers can be done with this technique using only opalescent or high translucent material. High aesthetics can be achieved as well as the added advantage that alterations can be done at any time.
