Do's and Don'ts of Porcelain Laminate Veneers
Types of Veneers

Veneers can be placed directly or indirectly. Composites are used for directly placed veneers, and a variety of materials can be used for indirectly placed veneers. These include:

1. Conventional powder-slurry ceramic (feldspathic porcelain). This type of porcelain is layered on the refractory die by the lab technician.
2. Heat-pressed ceramic. These products are melted at high temperatures and pressed into a mold created using the lost-wax technique (e.g., IPS Empress 1 and 2, OPC).
3. Machineable (CAD/CAM) ceramics (e.g., CEREC, E4D).
