A crown is a fixed prosthodontic unit which is commonly referred to as a cap. The purpose of this cap, as the name suggests, is to cover a structurally compromised tooth, restore its functionality in the oral cavity and protect it from further damage.
A crown may be fabricated using a number of materials based on the location of the tooth in the oral cavity, the patient’s aesthetic preferences, and budget. The three types of crowns that are widely used around the world include porcelain, metal and, porcelain fused to metal. Porcelain crowns are ideally suited for the restoration of anterior tooth, whereas the use of metal crowns is mostly restricted to the posterior dentition. Porcelain fused to metal, or PFM crowns are highly versatile, possess excellent properties of both materials and therefore can be used to restore any tooth in the oral cavity without chances of fracture or compromised aesthetics.
These units are indicated in a number of cases including:
- Root canal procedures
- Tooth fractures
- Permanently discolored tooth
- Natural or congenital discrepancies in the size or shape of teeth
Crown placement is a fairly simple, painless procedure. The tooth is first prepared by slightly cutting down margins and exposed surfaces to allow for better seating of the unit. An impression is then taken of the tooth to record fine anatomical details critical for crown design. Simultaneously, a shade is selected to match the color of the natural teeth present in the oral cavity. The crown is then fabricated in a laboratory using the impression and selected shade. Following a trial to check for proper fit, the crown is permanently fixed on top of the tooth using dental cements.
Crowns not only restore the functional aspect of the tooth, but also help the smile look more natural. Porcelain crowns are made to match the nature shade and texture of the teeth giving then high aesthetic value. Covering a tooth following extensive damage is essential in order to prevent complete loss of structure. Call today for a free Consultation
