E-max crowns : [Everything you need to know]
should restore back the aesthetic, strength, and functionality as close as possible to
a natural tooth. Crowns are indicated to restore fractured, crooked, stained teeth. They can be single crowns, bridges, or dental implant
of the technological progress in dentistry. However, it was difficult for many decades to find the perfect material that has all the advantages, without any cons and for an affordable cost. With the progress of technology in
dentistry, we are now able to make one of the best dental crowns: the
their affordable price. They result in a poor aesthetic appearance, allergic problems and too much damage for the natural tooth
crowns, both of these types give very pleasing clinical results.
E-max crown system
harvested for its excellent aesthetic
appearance, durability and strength. This makes E-max crowns
very strong and natural. Your dentist needs to remove only a thin layer of your tooth structure, unlike porcelain-metal mix crowns that
needed the removal of a lot of tooth structure.

Types of e-max restorations
With lithium desilicated you can make:
- · Inlays and onlays
- Minimally invasive crowns
- · Implant superstructures
- · Hybrid abutments
- · Three-unit bridges and up
- · Veneers
How are e-max Crowns made?
by removing a very thin dentine layer from the tooth, then a digital impression
using a 3D intra-oral scanner is made, this scan is transferred to a computer.
With the help of artificial intelligence, your future crown will be designed.
disilicate to produce the desired shape of the prosthesis. The shade has been
previously chosen by the dentist.
The advantages of e-max crowns
- Excellent aesthetics: An
important requirement for all dental crowns is that they should match the
natural tooth translucency and shade, e-max crowns have the closest aesthetic appearance
to natural teeth.
- High strength: Lithium
disilicate is a very strong material which makes e-max-crowns very durable.
- Large extensive indication
range: Inlays and onlays, crowns,
Implant superstructures, Hybrid abutments, bridges and Veneers can all be made
from lithium disilicate.
- Minimally invasive
preparation: The ceramic preparation doesn’t require the removal of much tooth structure, which makes e-max and zirconia a very conservative preparation.
- Clinical long-term success
and scientifically proven results: almost 3 decades of researches all showed
successful results in long term efficiency of e-max crowns.
- Large shades choice: the
monolithic block of Lithium disilicate comes in different shades depending on
the shade of the restored tooth and its adjacent.
- Adhesive, self-adhesive or
conventional cementation depending on the indication.
- Ability to be
Milled: Can be quickly fabricated by using CAD-CAM
milling which results in fast fabrication with the highest precision.
of e-max crowns
cost: the cost of e-max crowns is higher than zirconia and porcelain-metal mix
of fracture in the posterior area: e-max crowns are very thin and therefore
break easily in the posterior area, which makes them more suitable for restoring the front teeth.
bridge can be fragile: bridges of 3 and more crowns can be very fragile and
will risk breaking, especially in the posterior area because the masticatory forces in the molar area is higher than the front teeth area.
E-max vs Zirconia crowns
- Lithium Disilicate glass, an
- Better aesthetical results.
- More translucid.
- Larger shade choice.
- Very realistic.
- Great results in front teeth.
- Made of Zirconium Dioxide.
- incredibly strong.
- Difficult to crack.
- Less translucid.
- Opaque shades.
- Great results in posterior teeth.
- lack of capability to bond zirconia.
E-max crowns before and after
|e-max crowns before and after pictures : case n1|
This patient received 10 e-max crowns on his maxillary teeth, the result
is whiter, straighter teeth and symmetrical smile.
|e-max crowns before and after pictures : case n2|
porcelain-metal mix crowns on the central maxillary incisors, the shade is too
opaque and unnatural, the crowns are not well adapted on the gingiva and we can
notice the metal part of the crown which all gives an unsightly appearance. The
laterals and canines are a little bit crooked.
On the after side, the patient
received 6 e-max crowns that are well placed, the shade looks very natural and
is in harmony with the rest of the teeth.
|E-max crowns before and after : case n3|
Before receiving the new crowns, the patient had deep intrinsic stains
on his upper front teeth combined with some bad composite restorations, and 2
opaque zirconia crowns on the laterals. On the after picture, you see how the
e-max crowns succeeded in restoring the form of the teeth, the translucidity is excellent and the bite is so much better.
|e-max crowns before and after : case n4|
The patient here had 2 complains, he desired a brighter teeth shade,
and to correct his occlusion by straightening his teeth ( the patient
refused an orthodontic treatment). The result after putting 10 e-max crowns
was a magnificent occlusion and much more brighter teeth.
The cost of e-max crowns
E-max crowns are one of the
best options out there and this comes with a higher price than the traditional
dental crowns, and as we all know, it is impossible to set one price for e-max
crowns because it depends on the country, dentist, the dental laboratory and
many other things. But we tried to bring you an estimate of e-max crowns price in
different countries this year:
United States: $1000 to $1700
United Kingdom: £450 to £1400
Turkey: £ 229 – £ 400
What’s better than e-max crowns?
IPS e-max ZirPress
is a fluorapatite glass-ceramic
ingot which is pressed onto zirconium oxide, this combination improves the strength of e-max, making it possible to fabricate strong, long dental bridges
with minimized fracture risks. Nut this new technique doesn’t come with long
term efficiency studies yet.
