Key facts - E-max veneers are thin shells of lithium disilicate glass-ceramic (IPS e.max, made by Ivoclar), typically 0.3–0.6 mm thick, bonded to the front of the teeth. - They are stronger and more consistent than hand-layered feldspathic porcelain, which makes them a good choice for patients with a normal-to-firm bite. - Long-term studies report survival of around 95% at 10 years and 87% at 20 years for pressed lithium disilicate veneers. - Plan on 7–10 days in Turkey; e-max veneers usually cost £200–£450 each there.
Why Choose Lithium Disilicate?
E-max veneers in Turkey are often advertised as a separate product from "porcelain veneers", but they are a type of porcelain veneer. What makes them distinct is the material. Lithium disilicate is a glass-ceramic reinforced with needle-shaped crystals, giving it a flexural strength of roughly 400–500 MPa. Traditional feldspathic porcelain sits at around 70–120 MPa.
That strength has practical consequences. E-max veneers tolerate a slightly firmer bite, resist chipping at thin incisal edges better, and come out of the laboratory more consistently, because pressing or milling depends less on an individual ceramist's layering skill. The evidence is reassuring. A Turkish retrospective study of 364 pressed lithium disilicate veneers found 97.4% survival after 10 years, with very few fractures or debonds.1 A separate long-term series of 413 veneers reported survival of 95% at 10 years and 87% at 20 years.2
The trade-off is subtle. The best hand-layered feldspathic porcelain can achieve slightly more depth, translucency and individual character, especially on very thin, no-prep cases. For most patients, the difference is small. For patients with a heavier bite, or who want a predictable result across many teeth, e-max is often the safer choice.
The veneer-versus-crown question applies here as it does to every veneer. A veneer covers the front surface only, and the preparation should stay in enamel. If a clinic quotes "e-max veneers" but plans to reduce your teeth all the way round, you are being quoted e-max crowns instead.
Preparation and Bonding
Facial enamel is roughly 0.3–0.5 mm thick near the gum line and around 1.0 mm or more towards the biting edge. Pressed e-max veneers can be made as thin as about 0.3 mm, so the preparation can usually stay within enamel: typically 0.3–0.6 mm on the front surface, graded from the gum line to the edge.
Keeping the preparation in enamel is the single most important factor in how long veneers last. In a 12-year study of 580 porcelain veneers, those with preparations confined to enamel had 99% survival. Veneers bonded to dentine, or with margins in dentine, were about ten times more likely to fail.3
Preparation is guided by a mock-up of the approved design (see digital smile design). Teeth that already sit behind the planned outline may need little or no reduction. Crowded or rotated teeth may need clear aligners first to avoid bulky results.
E-max veneers are bonded rather than cemented: the ceramic is etched with weak hydrofluoric acid and primed with silane, then seated on etched enamel in a light-cure resin cement. Our adhesive bonding guide explains why e-max should never be sandblasted.
How E-max Veneers Are Made
E-max veneers are produced in one of two ways.
IPS e.max Press. The veneer is waxed up, invested and pressed from a ceramic ingot at around 915–920°C. Pressing produces very fine margins and is the preferred method for thin veneers.
IPS e.max CAD. The veneer is milled from a blue, partially crystallised block, then fired at around 840–850°C to reach full strength and its final shade. Milling extremely thin margins without chipping is more difficult, so CAD veneers are usually slightly thicker.
Ingots and blocks come in several translucency grades. High-translucency grades suit thin veneers on light teeth. Medium- and low-translucency grades give more body. Medium- and high-opacity grades help mask darker teeth, although severely discoloured teeth may need zirconium veneers or a thicker design.
The finish can also vary:
- Monolithic (stained and glazed): the strongest option, well suited to back teeth and firmer bites.
- Cut-back and layered: the incisal third is reduced and rebuilt with layering ceramic, adding depth and opalescence at the edge at a small cost in strength.
Your Treatment, Day by Day
Day 1: assessment and design. Photographs, scans and a clinical examination confirm which teeth need veneers, and whether whitening or orthodontics should come first. A digital design and wax-up follow.
Day 2: mock-up. A resin mock-up is placed over your teeth. You approve the length, shape and speech before anything is prepared.
Day 3: preparation. Enamel is reduced through the mock-up, the final scan is taken and the shade recorded. Temporary veneers reproduce the approved design.
Days 4–7: laboratory work. The veneers are pressed or milled, then stained, glazed or layered.
Days 7–8: try-in and bonding. Shade is confirmed with try-in paste, then each veneer is bonded and the bite adjusted.
Days 9–10: review. Gum response, bite and speech are checked, and a night guard is made if you grind.
What to Check in an E-max Veneer Quote
Material substitution. "E-max" is an Ivoclar brand name, not a generic term. Some laboratories use other lithium silicate or unbranded pressable ceramics and still call the result "e-max". Ask for the product (IPS e.max Press or CAD) and the laboratory's material documentation.
Veneers that are really crowns. Ask for the planned preparation depth in millimetres, and confirmation that the back of each tooth will not be touched. Ask to see photographs of the prepared teeth before bonding.
Tooth count. Most smiles need 6–10 veneers. Quotes for 20 or more, based only on photographs, often include teeth that do not show when you smile. In Turkey, expect roughly £200–£450 per veneer; the same treatment typically costs £700–£1,300 or more in the UK.
Is It Right for You?
| Good fit | Think twice |
|---|---|
| Healthy teeth with adequate enamel and a normal to firm bite | Severe crowding (until corrected), heavy grinding without a night guard, little remaining enamel, and active gum disease |
| Discolouration, chips, gaps or shape defects that whitening and bonding cannot resolve | Very dark teeth, which may need more opaque materials or a different restoration |
| Patients who want a predictable, durable result across several teeth | Risks include debonding (especially on dentine), chipping, sensitivity, marginal staining and gum inflammation from overcontoured margins |
E-max or Hand-Layered Porcelain?
Hand-layered feldspathic porcelain veneers can be made extremely thin and give the most lifelike translucency in skilled hands. They depend more on the ceramist and are weaker before bonding.
E-max veneers are stronger, more consistent and better suited to firmer bites, with excellent long-term data. For most patients both perform well when bonded to enamel. Feldspathic porcelain suits very thin, high-aesthetic cases; e-max suits patients who want a little more strength and predictability.
Frequently Asked Questions
Are e-max veneers better than porcelain veneers?
E-max veneers are a type of porcelain veneer, made from lithium disilicate rather than traditional feldspathic porcelain. They are about four times stronger and are made by pressing or milling, which gives more consistent results. Feldspathic porcelain can be layered by hand to be slightly more translucent and lifelike, and it can be made a little thinner. Long-term survival is excellent for both when they are bonded to enamel. E-max is usually preferred for firmer bites or many teeth; feldspathic porcelain for very thin, high-aesthetic cases on small numbers of teeth.
How thin can e-max veneers be?
Pressed e-max veneers can be made as thin as about 0.3 mm in places, with typical thicknesses of 0.3–0.6 mm. Milled versions are usually slightly thicker because extremely thin margins are hard to mill without chipping. Thinner veneers need less enamel reduction, which helps keep the bond in enamel, the most important factor in long-term success. Very thin veneers cannot mask much discolouration, however, so darker teeth may need a thicker or more opaque design. The required thickness should be decided from your mock-up and tooth colour, not from a standard package.
Can e-max veneers be whitened later?
No. Lithium disilicate does not change colour with whitening, so your veneers will keep the shade they were made in. If you want your natural teeth lighter, whiten them before treatment, wait about two weeks for the colour to stabilise and for residual oxygen to clear, and then match the veneers to the new shade. If you whiten later, your natural teeth may become lighter than the veneers. A professional clean and polish can remove surface staining from the veneers themselves, but it will not change their underlying shade.
Will my e-max veneers break if I grind my teeth?
E-max tolerates firmer biting than feldspathic porcelain, but heavy grinding can still chip or fracture any veneer, especially at the biting edges. If you grind or clench, the dentist should design the bite carefully, often with slightly thicker incisal edges or a wrap-around (incisal overlap) design, and make a hard night guard for you to wear every night. Signs of grinding include flattened edges, cracked fillings and morning jaw ache. Tell your dentist about these before treatment, so material choice and protection can be planned.
