When a tooth is damaged to the extent that it is not possible to do a filling, inlay or onlay, a crown is the alternative. Old crown techniques often used a metal base with a porcelain material on top for aesthetics. Today, we use strong ceramic materials instead of metal. The only exception is a golden crown, if requested.
Using strong, enamel-like ceramic materials we can most often (depending on the case) fabricate a crown in a day or two. Thanks to our advanced digital scanners, there is no discomfort while we make dental impressions. A two-minute scan gives us all the information we need, in full detail and the highest resolution. The crown is then crafted and cemented to the tooth – aesthetic, durable and strong.
The quality and lifespan of the ceramic crown depends on technique and time spent on the treatment.
A crown can look and feel right, but still have quality concerns. At Snö, we always document our procedures in order to ensure our high-quality standard. When a crown is suggested, you get a two-year warranty, irrespective of what happens to the filling. This can be extended to five years if you follow our maintenance instructions.
A damaged front tooth that had old composite fillings. Teeth were bleached before making the new ceramic crown.
The old technique to make a crown (at Snö we do not do this) with an inner shell of metal/gold.
The metal blocks out the light (left) and often discolours the tooth towards the gum. To the right, we have replaced it with a modern, biological, ceramic crown.
Front tooth fractured. The tooth (root filled many years ago) could, in this case, be lengthened with a ceramic post in order to place the full ceramic crown on top of the post.
Schematic drawing (cross section) of a healthy tooth (left) with enamel (white) dentine (more yellow) and the pulp anchored in the jaw bone and gums (red).
To the right, the tooth has been root filled and a ceramic post (white) has been cemented to the root and a crown (white with lines) placed on top of the post.
Ceramic crowns can also as this case be made on implants.
