Direct composite or bonded porcelain: a clinical choice for anterior aesthetics.

Choosing between direct composite resins and bonded porcelain veneers to restore permanent anterior teeth requires the dentist to evaluate both the aesthetic potential and the functional reliability of available bonding procedures. Direct composites are aesthetic, conservative and reliable, but demand technical and artistic skills, and have limited longevity. Bonded porcelain veneers can have excellent aesthetics, but require additional tooth preparation, exacting technique and laboratory support, and have an unknown life expectancy.
