A dental crown, also known as porcelain crown or ceramic crown is a dental restoration fabricated outside of patients in the laboratory settings by a technician. A dental crown can be made out of different materials like gold, ceramic, or porcelain fused to metal.
The dental crown procedure, however, is performed by a licensed dentist and requires significant skills. During the preparation process, the dentist will remove some of the tooth structure across the entire tooth to accommodate the new dental crown. Any compromised tooth structure, like decay or cracks, is also removed during dental crown prep.
Types of dental crowns
• All ceramic crowns, like eMax press
• Zirconia crowns
• Porcelain fused to metal crowns
• Gold crowns
The types of the dental crowns, in reality, describe the types of materials used to fabricate the crown but the concept and the process from the patient’s stand point is the same.
“Tooth Enamel is a translucent surface that can transmit up to 70% of light. Dentin can also transmit some of the light” as described in the Open Dentistry Journal. So when a dental crown is diagnosed, the position of the tooth, the bite and aesthetics have to be considered when choosing the right type of dental crown. The most popular type of dental crowns currently are Zirconia, and Emax Press crowns. They are metal free caps that have beautiful aesthetics and longevity.
A bridge is a special dental apparatus that spans, or bridges, the gap made by one or more teeth that have fallen out or been extracted. Bridges rest on the teeth on either side of the gap, which are usually protected by strong dental crowns, coverings that surround an entire tooth to provide strength.
While in the past dental bridges and removable dentures were the only option to replace missing teeth with progress in implant dentistry now patients and dentists have many options including implant crowns and implant bridges to replace a single missing tooth to multiple teeth, and implant dentures for a full mouth reconstruction.
What should I expect during a bridge procedure?
Bridges usually take two visits to complete. In the first visit, the teeth on either side of the gap will be shaped to make room for crowns, and an impression will be made of the gap so the bridge can be made to fit. Temporary crowns will be placed on the teeth to protect them while your bridge and crowns are being made.
At the second visit, the crowns will be placed on your teeth using a strong adhesive and the bridge will be attached as well. Fixed bridges are permanently attached to the crowns using a bonding adhesive while removable bridges attach using clips.
