Dental crowns are caps designed to aesthetically and functionally replace the natural crown of a tooth.
A natural tooth crown can become damaged as a result of fracture, decay, or tooth wear.
In addition to restoring function, crowns also correct aesthetic imperfections such as color, shape, and tooth alignment.
Today, patients can choose among various materials for dental crowns, and metal-free crowns represent the most advanced aesthetic solution in modern prosthetic dentistry.
What Are Non-metal Crowns?
Difference Between Metal-Ceramic and Metal-Free Ceramic
In the past, the material most commonly used for crowns and bridges was metal-ceramic.
This type of restoration has a metal base over which layers of ceramic are fused, giving the artificial tooth its shape, color, and size to blend naturally with the dental arch.
Although still widely used, modern dentistry now offers metal-free ceramics as a newer, more aesthetic alternative.
Advantages of Non-metal Ceramics
As the name suggests, metal-free ceramics are made without a metal base. The most commonly used material is zirconium, one of the hardest and most biocompatible materials in dentistry.
Zirconium-based metal-free crowns provide a more natural look, as they allow light to pass through the material, eliminating the artificial or grayish tone typical of metal-ceramic restorations.
They can be made from full zirconia or zirconia layered with ceramic, both resulting in highly aesthetic and natural-looking teeth.
When Are Zirconium Crowns Recommended?
Metal-free (zirconium-ceramic) crowns can be used for individual teeth as well as for bridges that replace missing teeth.
The tooth preparation process is similar to that for other types of crowns.
CAD/CAM Technology in Crown Fabrication
After taking impressions, CAD/CAM technology is used to scan and digitally design the restoration.
This ensures exceptional precision and a perfect fit on the prepared teeth.
Thanks to digital scanning and computer-guided fabrication, the process is faster, and crowns are usually ready for cementation within a few days.
In the meantime, patients wear temporary crowns that allow normal speech and chewing.
Benefits and Indications for Zirconium Crowns
Metal-free crowns are also recommended for patients with metal allergies, since zirconium does not cause any adverse reaction in surrounding tissues.
Research has shown that this material is completely safe and biocompatible.
Preparation Before Crown Placement
As with any prosthetic procedure, a clinical examination and X-ray analysis are required first.
Healthy teeth and gums are essential prerequisites for beginning any aesthetic or restorative treatment, including metal-free zirconium-ceramic crowns.
