There are various types of tooth restorations (prostheses) depending on the amount of missing tooth tissue. They can either be intracoronal: fillings and so called inlays and onlays, or extracoronal: crowns and bridges.
If one or more teeth are missing, they can be replaced by dental implants, bridges or removable prostheses. Bridges are for smaller gaps (maximum 3-4 teeth), and are attached by bonding agents. When multiple teeth are missing, bridges cannot cope with the mechanical stress (they might break, and own teeth could loosen and fracture), therefore removable prostheses are made.
None of the materials used in dental care are fully compatible with the hard tissues of human teeth, therefore restorations could be prepared using various materials meeting various requirements (mechanical strength, aesthetics, tissue-friendliness etc.): amalgam, gold, titanium, composite, dental porcelain, metal alloys such as gold-platinum, silver-palladium, nickel-chromium, or metal-free zirconia-oxide fulfilling the most rigorous aesthetic and biocompatibility requirements.
Zirconia restorations are produced with a unique technology. After taking an impression in our dental practice, the sample is scanned and forwarded to Sweden by email. There, they produce the white cap (Nobel Biocare — Procera), the internal structure of the restoration, which is then sent back to the dental technician to have the porcelain layers added. As a result, you get a fully white, artificial tooth restoration, which is not only biocompatible, but also beautiful!
It is translucent, and aesthetically the same as your own teeth. To fit the crown, your tooth is prepared via shoulder preparation. This procedure ensures that the crown edges fit the prepared surface more accurately. The gum “accepts” the restoration without any inflammation, and you will not see any dark crown edges.
Frequently asked questions and answers about tooth restoration
QUESTION: How long does it take to prepare a zirconia crown and how much pressure can it take?
ANSWER: Zirconia tooth restorations are prepared within 1.5-2 weeks. During this period, you will receive a temporary restoration on your tooth. The completed zirconia crown can take pressure similarly to your own tooth.
