E.max Veneers

e.max is a lithium disilicate ceramic. Lithium disilicate is available in low, medium, and high translucency forms and has reported flexural strength of 250 to 400 MPa.

Lithium disilicate has a wider range of anterior indications than leucite-based ceramics. A veneer may be unsuitable when there is clenching, grinding, a deep overbite, decay, or gum disease that has not been treated.

Placing a porcelain veneer can involve removing a small amount of enamel from the front and sides of the tooth. Because enamel is removed, veneer treatment is not reversible.

Ceramics can fracture when excessively flexed, and their hardness can wear opposing teeth. Veneers should not be placed over untreated decay or gum disease because existing problems may worsen.

A veneer may chip, crack, wear down, or loosen as time passes. It may then need repair, replacement, or re-bonding.

A shade is selected, the tooth is prepared, and an impression or 3D model is made. A laboratory makes the custom veneer, then its fit and shape are checked before cleaning and bonding.

A temporary veneer may be used while the laboratory makes the final veneer. The final appointment includes a check of fit and shape, any needed adjustment, cleaning, and bonding.

Zirconia is less translucent than lithium disilicate, while lithium disilicate has reported wear concerns compared with zirconia. Composite veneers are easier to fix when damaged but resist staining and wear less well than porcelain.

The appointment includes choosing a shade that matches natural teeth and checking the custom veneer before it is bonded. A temporary veneer may bridge the time before the laboratory veneer is ready.

Veneers are considered cosmetic dentistry and may not be covered by insurance unless medically necessary. Porcelain veneers tend to be more expensive than composite veneers.
