Types of orthopedic products made from E-max
Thin ceramic plates - veneers - are used to cover the front teeth. They are especially relevant when:
- Microcracks
- Chipped
- Significant distances between teeth
Inlays are an alternative to traditional fillings: they are intended for the restoration of teeth that are damaged by approximately 30-40%. Such products are usually used in the upper part of the chewing element, after caries has been eliminated.
Crowns and standard fixed dentures help restore teeth damaged by more than 60%.
Characteristics
Emax dental crowns are made of pressed ceramics based on lithium disilicate. Unlike traditional metal-ceramic structures, such prostheses do not contain a metal frame. This allows them to accurately reproduce the shade and transparency of natural enamel.
Dentures can withstand significant chewing loads. This feature allows them to be used even in the lateral parts of the jaw. Despite their strength, E-Max crowns are lightweight. Due to this, significant changes to the supporting teeth are not required when installing the structure.
The surface of the crowns is less susceptible to the formation of plaque and deposits. This helps prevent caries on adjacent teeth.
Advantages of E-Max crowns
Zirconium crowns are made using CAD/CAM computer design technology, converting impressions into digital format. Ceramic crowns are formed using the pressed casting method, which makes them more stable and suitable for the restoration of chewing teeth.
E-max ceramics can be used to make prostheses of various shapes - from lumineers (extremely thin overlays on teeth) and veneers (plates fixed to the outer side of the tooth) to regular crowns and bridges (structures replacing one or more teeth). The main disadvantage of E-max ceramic crowns is their high price.
Ceramic crowns e max have a number of advantages:
- Wear resistance The product can be used without fear of chipping or cracking
- Light weight and minimal thickness The absence of a metal base makes the structure lighter and thinner
- Natural appearance The material is highly transparent and has natural light reflectivity, which allows them to imitate natural teeth as accurately as possible
- Hypoallergenic properties The material does not interact with oral tissues, which eliminates any allergic reactions to the components
- Reliable fixation E-Max is well compatible with adhesive cements, which ensures strong installation
- Minimal tooth preparation Installation requires less grinding of healthy dental tissue, unlike traditional metal structures
Indications and contraindications
E-Max ceramic crowns are the optimal choice in a number of clinical situations. In particular, they are recommended for use in the following cases:
- Changing the color of the enamel. When teeth lose their natural color, the design effectively restores their appearance
- Aesthetic defects. Crowns help remove chips, cracks and stains on teeth
- The need for restoration. Such structures are intended to restore severely damaged or destroyed chewing elements
- Prosthetics after implantation. E-Max crowns can be used for implant prosthetics in any area of the oral cavity
There are also certain contraindications to installing Imax crowns. In particular, they should be abandoned against the background of high tooth wear, bruxism and the development of serious bite pathologies. They are not installed even if the central incisors are severely damaged.

Manufacturing technologies
In the process of creating emax crowns, 2 technologies are used - pressing and 3D milling.
The pressing method begins with wax modeling and taking an impression. The resulting model is sent to a special oven, where the final shape of the prosthesis is formed under the influence of pressure and temperature. Then, depending on the requirements for restoration, additional decoration is carried out (veneering, painting, glazing).
3D milling technology involves the use of CAD/CAM systems. They are essential for precise and automated production. After an intraoral scan of the patient, a computer program generates a 3D projection of the future prosthesis, which is then implemented on a milling machine. This method virtually eliminates errors in production, and the use of high-quality materials allows you to achieve high strength and aesthetic appeal of the product.
