Crowns are a type of restoration that covers the entire surface of the tooth. There are a variety of circumstances when you might need a crown. For instance, a crown is necessary for a tooth after a root canal treatment to protect it from fracturing. In other cases, when teeth are cracked or large portions of teeth are missing, a crown is necessary to provide lasting function of the tooth.
Crowns can be made from a variety of different materials, including porcelain, porcelain fused to metal, gold, and zirconia. Most often, porcelain is chosen due to its high strength and beautiful natural aesthetics. However, there are specific instances when other materials need to be utilized. The best suited material for the patient is chosen at the consult appointment.
Our office utilizes CEREC, a technology that allows us to put a porcelain crown on a tooth in one visit. Our new CEREC unit, the Omnicam from SIRONA, is a color 3-D scanning technology that scans prepared teeth for restorations. It also shows decayed and broken teeth in a life-like streaming video. This technology eliminates the need for traditional impressions and multiple appointments for a single crown restoration.
CEREC has over 30 years of clinical research and practical experience to support the success of this technology. More than twenty million restorations have been performed worldwide using CEREC technology.
The process begins by preparing the teeth for the restoration. First, diseased tissue and undermined tooth structure are removed. The prepped area and surrounding structures are then scanned by the acquisition unit, and the design of the crown is made by Dr. Tomenko and the CEREC software. Once the design is complete, Dr. Tomenko chooses the type, size, and proper color for a porcelain block to make your porcelain restoration. The block is inserted into the milling unit, which carves the crown in a matter of minutes. Once the milling is completed, the new beautiful porcelain restoration is ready for fitting. Final shaping is accomplished chairside and glazing or firing may take place before cementation.
Dr. Tomenko has been using CEREC for the last four years to provide excellent service to her patients, and has extensive training in the technology. If you would like to talk to Dr. Tomenko about this service, please call to schedule your free consultation today!
