Standard Metal-Ceramic Crowns (3-Year Warranty)
Service Detail – Standard Metal-Ceramic Crowns (3-Year Warranty)
If you have missing teeth, broken or chipped teeth, pitted enamel, or severe discoloration due to antibiotic use, your dentist may recommend porcelain crowns.
There are various types of porcelain crowns available, including all-ceramic crowns, precious metal-ceramic crowns, and titanium-based ceramic crowns.
Porcelain crowns consist of two layers:
- An inner framework (core) for strength.
- An outer porcelain layer for aesthetics and durability.
Porcelain crowns are classified into two main types:
- Metal-Ceramic Crowns – These have a metal core with a porcelain coating.
- All-Ceramic Crowns – These have a full ceramic structure for a more natural appearance.
What Are Metal-Ceramic Crowns?
When a metal framework is tightly fitted around the tooth core, a layer of porcelain is applied over this metal. Metal-ceramic crowns can be used for both front and back teeth. These crowns are strong enough to withstand heavy chewing forces while also offering good aesthetics.
However, there are some drawbacks to metal-ceramic crowns:
- While they provide good aesthetics, they may not be as visually pleasing as full-ceramic crowns.
- The porcelain layer may crack, chip, or break over time.
The metal framework underneath the porcelain can sometimes appear as a dark line along the gum line. Dentists typically place this line below the gum, but if the gums recede, the dark edge may become visible, affecting the overall appearance of the tooth
What Are Standard Metal-Ceramic Crowns?
Standard metal-ceramic crowns are often referred to as Nickel-Chromium (Ni-Cr) metal-ceramic crowns. This type of crown has the longest history of use and was one of the first to be developed.
However, due to its aesthetic limitations and the emergence of higher-quality, more aesthetic porcelain options, standard metal-ceramic crowns are now less commonly used for cosmetic dental restorations.
