A porcelain crown (or cap) is a covering that encases the entire tooth surface restoring it to its original shape and size. A crown protects and strengthens tooth structure that cannot be restored with fillings or other types of restorations.
Although there are several types of crowns, porcelain (tooth colored crown) are the most popular, because they resemble your natural teeth. They are highly durable and will last many years, but like most dental restorations, they may eventually need to be replaced. Porcelain crowns are made to match the shape, size, and color or your teeth giving you a natural, long-lasting beautiful smile.
A crown procedure usually requires two appointments. Your first appointment will include taking several highly accurate molds (or impressions) that will be used to create your custom crown. A mold will also be used to create a temporary crown which will stay on your tooth for approximately two weeks until your new crown is fabricated by a dental laboratory.
While the tooth is numb, Dr. Florin Arhiri will prepare the tooth by removing any decay and shaping the surface to properly fit the crown. Once these details are accomplished, your temporary crown will be placed with temporary cement and your bite will be checked to ensure you are biting properly.
At your second appointment your temporary crown will be removed, the tooth will be cleaned, and your new crown will be carefully placed to ensure the spacing and bite are accurate.
Chairside Economical Restorations of Esthetic Ceramic (CEREC) has revolutionized dental procedures. Traditionally, if crowns, onlays, inlays or dental veneers were required to restore damaged teeth, multiple procedures and a great deal of waiting time in-between would be inevitable. CEREC creates these ceramic restorations within minutes in the dental office. This means that many treatments can be completed in just a single visit.
CEREC is comprised of several computer-assisted design (CAD) tools and a milling machine that creates custom ceramic restorative devices. CEREC can benefit almost anyone needing a ceramic restoration. This is of great benefit to nervous patients, and it can also reduce the cost of treatment.
CEREC can benefit almost anyone needing a ceramic restoration. Exceptions include patients who have a prior history of breaking ceramic devices and those with a deep bite. CEREC devices are proven to last for over 5 years, but recent research indicates that most CEREC-created restorations last for more than 10 years.
Additional advantages associated with CEREC include:
The first step in the procedure is preparing the tooth for the restoration. Depending on your particular case, the dentist will take photos of your affected teeth using one of CEREC’s two imaging solutions. If using CEREC Omnicam, the dentist will take several images of the tooth, sending a three-dimensional, colored model to the CEREC machine. If using CEREC Bluecam, the dentist will coat the teeth with a contrasting agent before taking images of your teeth.
These images are transposed onto the computer screen, where the dentist will view the tooth from every angle and design the final restoration. When the design is complete, it will be transmitted to the milling unit. The dentist will insert a block of ceramic, matching your tooth color, into the milling machine which will then create the full crown, onlay, inlay, or veneer. Before affixing the restoration to the tooth, the dentist will perform a dry fit to ensure comfort. Once a perfect fit is established, the restoration will be polished and affixed to the tooth with dental cement.
