Layered Vs Solid Zirconia: Everything you need to know.

Layered zirconia restorations help overcome both the highest aesthetics and the strength and flexibility you need for all anterior and rear cases. Its fabrication consists of Zirconia ribs inside and is covered with a layer of porcelain outside. With the multi-layered zirconia crown, you can imitate the shade gradient seen in natural teeth. Various grades of such zirconia are recommended for a variety of indirect dental restorative applications, in accordance with their unique properties. Layered zirconia restoration is flexible and offers alternatives for full mouth restorations, crowns, bridges for both front and rear regions of the mouth. Because of its durability and aesthetics layered zirconia crown cost has the best value possible.

Benefits of layered zirconia crowns

• Suitable for both front and rear crowns and bridges
• Offers the highest level of aesthetics
• No limitation on the design of size or length of restoration
• No dull black lines at the gingival margins
• Metal free restoration
• Can easily be adjusted to chair-side
• Hypoallergenic
• Biocompatible
• Translucent Porcelain

Solid zirconia is suitable if you need a crown that requires minimal clearance or if you suffer from severe bruxism. This restoration is a possible alternative for rear crowns and bridges. Full-solid zirconia may not have the same aesthetics as the layered version, but it allows fully customized size, shaping and shading with sheer strength. Fabricated out of 100% monolithic medical-grade zirconia, it is much stronger than porcelain/ metal fused restorations. They are virtually unbreakable meaning even patients having the most severe form of bruxism won’t have fracturing issues.

Benefits of solid zirconia crowns

• Long lasting reliability
• Ideal for extreme bruxers who have destroyed their natural teeth or previous restorations
• Glazed to a smooth surface resulting in reduction of plaque accumulation
• Customizable size, shape and color
• Minimal tooth removal or lower labor requirements
• Aesthetic replacement for precious alloys
• Low thermal conductivity
• Avoids grinding and wear down on opposing teeth

Applications of layered zirconia and solid zirconia

The applications of layered zirconia substructure generally have a flexural strength of 1200 MPa, comparing fairly to traditional porcelain fused to metal crowns. The fracture toughness and flexural strength of layered zirconia are extensively higher in comparison to alumina or any other all-ceramic materials. Designed and milled using CAD/CAM technology, full-solid zirconia restorations are forged for over six hours at 1,500 °C.

Layered and solid zirconia- Which one is best for tooth restoration?

Both types of zirconia restoration possess equally good quality. Depending on your oral health condition and location of the restoration, the doctor will recommend which type of tooth is suitable for you. Choosing between layered Vs solid zirconia for molars and premolars full-solid zirconia restoration will be ideal as it has super high durability. The strength, flexural strength, and load capacity may be weaker compared to the original zirconia crown, however layered Zirconia can satisfy both the highest aesthetics and the durability. For the position of the 2nd teeth, incisors, canines, doctors can recommend you choose from solid or layered Zirconia.
