Restorations
Crown
A dental crown is a tooth-shaped cap placed over a damaged, decayed, or aesthetically poor tooth to restore its shape, size, strength, and appearance.
Crowns are typically made from porcelain, zirconia, gold alloy, or metal-fused-to-porcelain. Modern CAD/CAM systems allow same-day ceramic crowns milled in-office, often using intraoral scanners such as the Primescan 2.
When a crown is needed
- After a root canal treatment
- To protect a tooth weakened by a large filling
- To cover a dental implant
- For cosmetic improvement of misshapen or discoloured teeth
How long do crowns last?
With good oral hygiene, modern crowns typically last 10–15 years; high-quality zirconia crowns can last considerably longer.
