An E-max crown is a dental restoration made from a single block of lithium disilicate, strong and aesthetically pleasing all-ceramic material. They are mostly used for front teeth restoration.
The E-max system uses lithium disilicate glass, which includes quartz, lithium dioxide, phosphorus oxide, aluminum oxide, potassium oxide, and trace elements. Crowns are milled from a single ceramic block; thus, they possess great strength and durability. It can be fabricated using CAD/CAM technology in a single dental visit.
E-max crowns have become very popular to be used in aesthetic dentistry because they offer excellent aesthetics, strength, and durability. They are used in anterior crowns, veneers, and short span bridges for front teeth restoration.
Best Fitting and Appearance: E-max crowns are more translucent; thus, they are closer to a natural tooth in appearance; therefore, they are perfect in front teeth restoration. They are more transparent than zirconia crowns.
Fully Ceramic Prosthesis: E-max prostheses do not contain any metal alloys; thus, it gets rid of the unsightly gray line often left at the gum line by metal-based crowns.
Robustness: E-max crowns are made from lithium disilicate, making them highly resistant to cracks and breaks, with fewer fragments than zirconia crowns.
Fast Production: E-max crowns can be produced rapidly using CAD/CAM milling from high-quality monolithic blocks. The dentist prepares the tooth, takes a digital impression, and the crown is ready to be cemented in a single session.
Preservation of Tooth Structure: The strength of E-max crowns allows them to be made with thin sections requiring minimal removal of the natural tooth structure—a blessing for oral health.
Many Restoration Options: The E-max system can be used not only in crowns but also in veneers, inlays, onlays, overlays, and short span bridges for front teeth.
Crooked teeth: Restores the structure and shape; more to the front teeth
Teeth with root canal treatment: Provides strength and beauty to brittle teeth
Broken teeth: Restores teeth broken by decay or trauma
E-max crowns can be made in a dental lab or made directly in the clinic. For same-day crowns:
The dentist removes a thin layer of the tooth.
Digital impressions are taken via an intraoral camera.
The impression is processed via computer for milling.
A milling machine shapes the crown from a lithium disilicate block.
The dentist fits and bonds the crown to the tooth. This can usually happen within 1-2 hours.
Yes, E-max crowns are durable, natural-looking, and require minimal tooth removal. Consult your dentist to determine if they are suitable for your dental needs.
With proper care, E-max crowns can last significantly longer than the average 5-15 years.
No, they do not stain easily. However, superficial discoloration from foods like coffee or red wine can be removed with professional cleaning.
No, crowns cannot be whitened. Professional cleaning and teeth whitening should be done prior to selecting a crown shade.
