Preparation:
- Eliminate sharp edges, undercuts, and grooves.
- Provide suffi cient reduction (1.2 mm to 1.5 mm).
- Provide adequate space for the coping and dental ceramic porcelain.
- Avoid sharp angles on the occlusal surface.
- Avoid creating a deep fossa/cavity.
- Provide suffi cient (1.5 mm to 2 mm) occlusal/incisal reduction.
- Avoid preparations that are excessively tapered or too close to parallel. The ideal total occlusal convergence is 6–10°.
Impression
Make an ordinary crown and bridge impression using your preferred impression material and method. Send the impression to the laboratory.
Laboratory Procedures
A model is made from the impression and scanned for producing a NobelProcera Crown. After production, the crown is veneered with dental ceramics.
Cementation
Gently seat the restoration on the tooth and check both the occlusion and the interproximal contacts. The restoration should be in light occlusion. Excursive contact should be minimal.
Note: Do not use temporary cement due to an increased risk of fracturing all-ceramic crowns.

Improving Existing Teeth
If a tooth is damaged or of poor quality, a new ceramic crown is probably the best solution. Installation is fast. The end result is fantastic.
The all-ceramic NobelProcera™ crown has many advantages over traditional crowns. Besides its high esthetic qualities, the function and longevity of the crown is excellent as well.
Benefits of a new Procera crown:
- Superior esthetic result, compared to traditional crowns
- Easy installation, quick results
- Short and convenient treatment
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.
Course of Treatment
Placing a new crown step-by-step
The course of treatment described here is one of several options available. Consult your dentist to find out what the best solution is for you, given your specific condition.

|
|
|
1. Before the 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.

Alternatives to an All-Ceramic Crown
 |
Porcelain fused to metal
Simply put, a new all-ceramic NobelProcera 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.
