In dentistry, a veneer is a thin layer of restorative material placed over a tooth surface, either to improve the aesthetics of a tooth,
or to protect a damaged tooth surface. There are two main types of material used to fabricate a veneer, composite and dental porcelain.
A composite veneer may be directly placed (built-up in the mouth), or indirectly fabricated by a dental technician in a dental laboratory, and later bonded to the tooth, typically using a resin cement . In contrast, a porcelain veneer may only be indirectly fabricated.
Laminates are thin dental veneers that are constructed in dental laboratory by dental technicians and bonded directly on the tooth surface. these are conservative techniques used to either change either shade of tooth or to improve its esthetic appearance.
Dental Lumineers are ULTRA THIN VENEERS which has been recently introduced in market . this technology has become possible by introduction of CAD/CAM machines in dentistry. These are the most conservative porcelain veneers which are only 0.3 -0.8mm thick.
