How veneers are made
Making porcelain veneers starts with a model (Figure 1) which has a removable refractory die (Figure 2), on top fo which the ceramist layers different porcelains using a pointy brush. Different layers are built progressively and then baked in an oven at over 900 degrees celsius (Figure 3, 4, 5).
After contouring and refining the surface with diamond burs and abrasives, a final bake is run to give the porcelain the final gloss and seal the surface. Afterwards, a final polishing is done with silicones to match the luster of the existing dentition (Figure 6).

After the completion of the ceramic layering and finishing, the veneer needs to be retrieved from the supporting material where the porcelain has been baked upon, using air abrasion (Figure 1) and verify that it will adapt flawlessly in the mouth. A contact paste (Figure 2 and 3) is used to detect any interference (Figure 4 and 5) which is released using a diamond bur if necessary to ensure a intimate seating of the restoration. At this point the veneer is ready to be tried intra-orally. (Figure 6)
