Tooth Appearance and Restorative Treatments
Zirconia and Porcelain Crowns
A dental crown is a restoration that encircles most of the tooth. It may be used in cases of extensive tissue loss, fracture, large fillings, some colour/form problems, or in prostheses on implants.

The difference from a laminate
A laminate mostly covers the front surface, whereas a crown wraps around the tooth more widely. If the tooth has already lost tissue to a large extent, a crown may be more appropriate.
Digital impressions
In suitable cases a digital impression can be taken with an intraoral scan. The gum margin, the quality of the preparation, the bite and the clinical fit of the restoration are also carefully checked by the clinician with the digital method.
Frequently asked questions
Does zirconia look natural?
The optical properties of the material, the thickness, the framework design, the shade selection and the laboratory craftsmanship affect the result.
Is zirconia made on an implant?
Yes, zirconia-based restorations can be used for crowns and bridges on implants. The connection design varies with the case.
Does a crowned tooth necessarily have root canal treatment?
No. Root canal treatment is only carried out when it is necessary for the health of the pulp.
Can decay occur under a crown?
The crown itself does not decay; however, decay can develop in the natural tooth tissue around the margin. Oral hygiene and check-ups are important.
Treatment duration
It includes the preparation, a digital or conventional impression, laboratory production and the try-in and bonding stages; the time varies with the case and the laboratory workflow.
When it may not be suitable
To preserve sound tooth tissue, it is important to avoid a crown preparation that is not necessary. If the tooth has not lost tissue to a large extent, more conservative options are assessed.
