E-max crowns

At the Kiadent Author Prosthetics Dental Clinic, you can have E-max ceramic crowns installed at a price below the average cost in Odessa.

IPS e.max is a monolithic ceramic system from the company Ivoclar Vivadent (Liechtenstein).

It is intended both for single restorations in the anterior section and for highly aesthetic bridge prostheses from 3 to 12 units.

Since its market introduction in 2005, E-max ceramics have earned the trust of prosthodontists and dental technicians worldwide, including in Ukraine. It consists of 70% lithium disilicate crystals, whose light-transmitting characteristics match natural enamel.

Indications

• the tooth is affected by caries by more than 50%;
• significant non-carious destruction of the tooth (wedge-shaped defect, chip, enamel wear);
• restoration of one front tooth;
• restoration of several consecutive missing units in the smile zone (with single crowns or a bridge prosthesis );
• allergy to metal.

Contraindications

• bruxism;
• presence of a large number of composite fillings.

Ivoclar Vivadent produces the following range of materials from which highly aesthetic metal-free crowns can be made.

Press

Pressable blanks made of lithium disilicate (LS2) glass-ceramic, possessing a strength of 470 MPa. The use of adhesive fixation techniques allows making crowns with a thickness of only 1 mm.

Press Multi

An improved version of the IPS E-max Press material, whose main difference is polychromy. The gradation of shades and translucency matches natural enamel—a transition of shade from white at the cutting edge to yellowish in the cervical zone. Restorations made from IPS e.max Press Multi offer the best aesthetics.

CAD

The crown is milled from a solid block of E-max ceramic on a milling machine using CAD/CAM technology. The resulting products are slightly inferior in strength to prostheses made from pressed e.max Press ceramics and have fewer shade selection options. This technology is used to make single metal-free constructions.

ZirCAD

High-strength zirconia oxide blocks (from 850 to 1200 MPa), from which restorations with increased mechanical stability, thin walls, and an aesthetic appearance can be made. Prosthetic constructions from E-max ZirCAD require minimal tooth preparation.

ZirPress

Fluorapatite glass-ceramic blocks are pressed onto IPS e.max ZirCAD frameworks. This type of glass-ceramic is in demand for bridge prostheses longer than 5 crowns. There are blanks in three opacity variants of A-D colors and four bleached BL colors.

IPS e.max Ceram

Nano-fluorapatite ceramic designed for layering onto any material from the IPS e.max range. It allows the prosthodontist to achieve a flawless aesthetic result with the effect of natural light scattering.

Advantages

• Flawless aesthetics. Thanks to the ability to transmit light, E-max crowns are indistinguishable from natural teeth and do not alter the color of the gum contour.
• Minimal preparation. Imax crowns are thin, requiring minimal enamel preparation and no depulpation of the supporting tooth.
• Hypoallergenic. Lithium disilicate is a biocompatible material that does not cause allergies, unlike metal and metal-ceramic prostheses.
• High strength. E-max ceramics are not inferior to metal in terms of strength indicators and are practically not susceptible to chipping, while offering high aesthetics.
• Adhesive fixation. They are fixed to the tooth according to a special protocol that prevents decementation.

Disadvantages

• Cost. The only disadvantage of metal-free Imax crowns is the relatively high price (1.5 times more expensive than metal-ceramic ones).

Aesthetics

In terms of aesthetics, E-max crowns are definitely better, as they have no framework and closely match the optical properties of a natural tooth.

Strength

Solid zirconia products are slightly stronger than E-max prostheses. However, if comparing zirconia dioxide crowns with ceramic veneering to prostheses made from E-max, the latter are stronger.

Biocompatibility

Both materials are absolutely hypoallergenic and do not cause allergic reactions.
