CROWNS
A dental crown is a tooth-shaped “cap” that is placed over a tooth to cover the tooth to restore its shape and size, strength and improve its appearance.
The crowns, when cemented into place, fully encase the entire visible portion of a tooth that lies at and above the gum line.
WHY IS A DENTAL CROWN NEEDED?
A dental crown may be needed in the following situations:
- To protect a weak tooth (for instance, from decay)
from breaking or to hold together parts of a cracked tooth. - To restore an already broken tooth or a tooth that
has been severely worn down. - To cover and support a tooth with a large filling when
there isn’t a lot of tooth left. - To hold a dental bridge in place.
- To cover misshapened or severely discolored teeth.
- To cover a dental implant.
- To make a cosmetic modification.
WHAT TYPES OF CROWNS ARE AVAILABLE?
Permanent crowns can be made from all resin, all ceramic or zirconia.
All-resin dental crowns are less expensive than other crown types.
However, they wear down over time and are more prone to fractures than porcelain fused to metal crowns.
All-ceramic or all porcelain dental crowns provide better natural color match than any other crown type and may be more suitable for people with metal allergies. All ceramic crowns can be used for front and back teeth.
Temporary vs. permanent
Temporary crowns can be made in your dentist’s office, whereas most permanent crowns are typically made in a dental laboratory. Typically, temporary crowns are made of an acrylic-based material or stainless steel and can be used as a temporary restoration until a permanent crown is constructed by a lab.
Dental zirconia crowns are a type of dental restoration used to replace damaged or decayed teeth. They are made from zirconia, a strong and biocompatible ceramic material known for its durability and natural appearance. Zirconia crowns offer several advantages, including high resistance to wear, chipping, and cracking. They provide excellent aesthetic results and are often preferred for their strength and long-term durability.
The resistance of zirconia crowns 500MPA, refers to their ability to withstand forces during normal oral function. Zirconia has high flexural strength, which means it can withstand biting and chewing forces without breaking or fracturing. This strength makes zirconia crowns highly resistant to wear, ensuring their longevity and reducing the need for frequent replacements.
