Ceramic crown E.max in Warsaw – a premium solution for your smile
E.max is a crown made of lithium disilicate ceramics, the strength of which exceeds ordinary enamel by 3-4 times. It withstands loads comparable to biting nuts and crackers. The thickness of the crown is 0.3 mm, so during grinding a minimum layer of the tooth’s own tissues is removed. The material has high transparency, which allows us to recreate a natural shade and make the crown invisible in daylight.
Dental restoration at Astra Dent is carried out using CAD/CAM technologies, which ensure the fit of the ceramic crown E.max with an accuracy of up to 20 microns – this is several times thinner than a human hair. Each stage is monitored under a dental microscope, which allows us to detect the smallest microcracks and guarantees a fit without gaps.
Why do patients choose Astra Dent Warsaw for the installation of an E.max ceramic crown?
The choice of dentistry for prosthetics is crucial, because the durability of the result depends on the quality of the work of the doctor and the dental laboratory. It is the accuracy of the fit of the crown that determines its service life. Therefore, it is important that the medical institution has modern equipment and works with reliable materials.

What is an E.max ceramic crown?
E.max refers to modern metal-free structures based on lithium disilicate ceramics. According to the Ivoclar Vivadent manufacturer, the material has a strength of up to 400 MPa, which is almost twice as strong as traditional ceramics and composite materials.
The main characteristics of E.max ceramic crowns:
- Composition. The base is made of lithium disilicate glass, which contains crystals that strengthen the structure of ceramics without the need for a metal framework.
- Thickness. The minimum thickness is 0.3-0.5 mm, so a thin layer of enamel and dentin is removed during preparation, while the natural structure of the tooth is preserved.
- Transparency. The properties of the material allow you to imitate natural enamel, repeating its light transmission. The color of the crown is easily selected according to the Vita scale, due to which the restoration is almost invisible.
- Manufacturing method. Crowns are created using CAD/CAM technology. After digital scanning, a 3D model is formed, which is milled from a monolithic ceramic blank.
The E.max crown is suitable for restoring anterior and posterior teeth, veneers, onlays, overlays, small bridge-like prostheses in the frontal area. It is equally effective for single restorations and combined structures.
The process of manufacturing and installing an E.max ceramic crown
Modern prosthetics methods allow us to restore a tooth with minimal intervention in healthy tissues. For this, Astra Dent specialists use digital diagnostic technologies and CAD/CAM systems, which ensure accurate fitting and a stable result. Installing a ceramic crown takes place in several stages:
- Consultation and diagnostics. At the first appointment, the doctor conducts a clinical examination, takes a digital X-ray or CT scan to assess the roots and tissue condition. They determine the indications for installing the crown and draw up an individual treatment plan.
- Digital impression. Astra Dent uses an intraoral scanner that creates a 3D model of the dentition with an accuracy of a few microns. The method replaces classic silicone impressions and provides comfort.
- CAD/CAM manufacturing. Using software, the specialist designs the shape of the future crown, after which it is milled from a monolithic block of E.max lithium disilicate ceramic. At the final stage, crystallization is carried out in the oven, which adds strength to the material.
- Fitting and fixation. The doctor checks the finished crown for accuracy of fit, bite and aesthetics. After correction, it is fixed with adhesive cement, which ensures tightness and reliability of fixation.
Thanks to the consistent actions of specialists, the patient receives a crown that accurately reproduces the shape and color of the tooth and fits without microcracks. This improves the aesthetics of the smile and protects against repeated caries.
Advantages of E.max for patients
Studies show the stability of lithium disilicate ceramics in the long term. According to the Journal of Prosthodontics, the survival rate of crowns for 10 years was 86.1%, while other authors note even higher figures – over 96-99% in the Malament study. In addition, they have a number of features that are important for patients in everyday life:
- Aesthetics. The material is highly transparent and has the ability to imitate enamel, so the color and shine of the crown does not differ from the neighboring teeth in natural light.
- Biocompatibility. Lithium disilicate ceramics do not cause allergic reactions and do not oxidize, so the gums retain a healthy color and do not darken at the edge of the restoration.
- Strength. Average bending strength indicators reach 360-400 MPa, which provides resistance to cracks and chips during chewing.
- Durability. Studies confirm that more than 9 out of 10 crowns serve without replacement for at least a decade, provided that proper hygiene and control by the dentist are maintained.
- Color stability. Ceramics do not change shade over time, do not absorb dyes from coffee, tea or wine, which is important for patients with high aesthetic requirements.
- Comfort in use. The smooth surface of the crown does not accumulate plaque and provides a natural feeling when chewing.
The combination of the above characteristics makes E.max one of the most predictable and durable solutions in aesthetic dentistry in Warsaw. Patients get a good result immediately after fixation and a stable effect for many years.
Comparison with other crowns
The material for a crown is selected depending on the clinical situation, aesthetic requirements and budget. Each type has its own advantages and limitations. The long-term survival of ceramic structures is on average >90% at 10 years, while metal-ceramics retain similar strength indicators, but lose transparency and naturalness of color.
The table shows the main differences between common types of crowns:
| Material | Strength and flexibility | Aesthetics | Biocompatibility | Thickness/ tooth preparation | Durability | Peculiarities |
| E.max | 360-400 MPa | High transparency and natural colour | Excellent | 0,3-0,5 mm | >90% 10-year survival | Optimal choice for the frontal area with the possibility of use for veneers and onlays |
| Metal-ceramics | 600-800 MPa | A dark edge near the gums is possible | Possible allergies to metal | 1,5-2 mm | >90% 10-15 -year survival | Reliable for chewing teeth |
| Zirconium (monolithic) | 900-1200 MPa | Unnatural white colour | High | 0,8-1 mm | >95% 10-year survival | Ideal for bridges and the occlusal region, but not for the anterior region due to low translucency |
| Monolithic ceramics | 100-160 MPa | The best aesthetics | Excellent | 0,5-0,7 mm | 70-80% 10-year survival | Used primarily for veneers and restorations in the anterior region |
