The laminates are extremely thin (thinner than finger nails) veneers of porcelain. They are held in place by a bonding resin cement. The word “bonding” is somewhat of a misnomer as there is very little true adhesion involved. The enamel surfaces of the teeth and the inside surface of the porcelain are etched with an acid solution. This creates microscopic crevasses in those surfaces. A liquid plastic is flowed over these areas and filters down into the tiny crevasses. The plastic is then hardened with the rest of the cement with an intense light source. A silanating agent that has double bonds for porcelain and the resin cement will provide some mild adhesion for that interface and the new generation dentin bonding agents will also help adhere to areas where the dentin , the inner layer of the tooth, shows through. The resin cement can also help with the color of the tooth. The cement is naturally translucent, however, different agents can be added that can change the color and the opacity of the laminate, thus masking any problems with the underlying teeth.
