A dental crown is a tooth-shaped "cap" that is placed over a tooth – covering the tooth to restore its shape and size, strength, and/or to 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. |

Types of Dental Crowns |
|
|
|
|
| |
There are three basic types of materials for dental crowns: |
|
|
|
|
| |
- Porcelain fused to metal (PFM) dental crowns
- All porcelain dental crowns
- All metal dental crowns
|
|
|
|
|
| |
Course of treatment |
|
|
|
|
| |
In the best case, the new crown is installed in two dentist visits in one week's time. The inconvenience and after-effects will be minimal. |
|
| |
|
|
|
|
|
| |
1. Before procedure |
|
|
|
|
| |
The dentist makes a first evaluation and makes an impression of the existing crown. The impression is used as the prototype for the new crown. |
|
|
|
|
|
 |
|
|
|
|
| |
2. Preparing the old tooth |
|
|
|
|
| |
The natural tooth is given minor preparation or adjustments. A temporary crown is attached. |
|
|
|
|
|
 |
|
|
|
|
| |
3. Placing the new crown |
|
|
|
|
| |
A week or so after the first visit, the permanent crown is securely fitted. Normally, it will serve its owner for life.. |
|
|
|
|
|
 |
|
|
|
|
| |
4. End result |
|
|
|
|
| |
The end result is a new tooth that should blend in perfectly with the others. Brush and floss as recommended by your dentist or dental hygienist. |

Alternative to an all-ceramic crown :
|
|
|
|
|
| |
Simply put, a new all-ceramic Procera crown is esthetically superior to any other type of crown. You just can't get the same finish and natural, living look with a traditional metal core crown. However, the latter is an established and well-known solution. This is probably why it is still commonly used, even though function, installation and price are normally equal to that of a ceramic crown. |
