Microleakage of computer-generated Vita Cerec and Vitadur-N laminate veneers.

Laminate veneers are now used as conservative aesthetic alternatives to full coverage restorations in some cases, especially in young adults and children. With the development of improved restorative resin systems and the acid etch technique, thin preformed plastic laminate veneers were bonded to the labial surfaces of discolored, developmentally deformed or fractured teeth. However, aesthetic failure due to color instability, staining and wear happened. Now, with bonded porcelain veneers it is possible to achieve both an aesthetic result and a veneer preparation while restoring the function of anterior teeth. They are also used to restore fractured incisors. Ceramic veneers hold advantages over composite resin veneers in color stability, were resistance and lifelike aesthetics.
