Crown appointments are scheduled for 2 hours. This involves 30 minutes of actual work inside your mouth. This 30 minutes includes pre-operative and post-operative procedures. After the tooth’s nerve and bone has been diagnosed, preoperative topical and local anesthesia are administered to provide numbness so the tooth preparation can be completed. A tooth preparation is completed with a electric hand piece specifically used for efficient removal of tooth and filling structures. After the tooth preparation, retraction cord and paste are used to create a clean space for accurate 3 D scanning. These are gently packed (pushed) between the tooth and gum tissue. A rubber mouth prop is recommended at this point for comfort and working stability. Once a clear field has been established, a 1 minute scan is made of the tooth and surrounding structures. The scanning machine has built-in music or noises that provide guidance for scanning. Once the scan is completed the machine is disinfected and removed from the room for the design and manufacturing of your crown. This typically will take 45 minutes. During this time you are encouraged to remain in the operatory chair with limited talking and movement. This helps maintain the local anesthesia and moisture control provided at the beginning of the procedure. Once the crown is ready an assistant carefully rinses your mouth in preparation of inserting the crown. Prior to cementing the crown, your gums are inspected for cleanliness and the crown is inserted checking for proper fit. At times minor adjustments are made chair-side for proper fit upon the tooth and against the neighboring teeth. When a proper fit is confirmed, a clear field is established by the assistant by retracting your cheeks, lips and tongue. We specifically use Relyx Ultimate cement which is made for ceramic crowns. This requires bonding agent application to the tooth and inside of the crown. Air is used to thin the coats of bonding agent. Cement is syringed into the crown, then inserted upon the tooth. A blue light is used to harden the cement prior to removal. Floss and dental scaling instruments are used for cement removal. Once the cement is removed and confirmed with a radiograph (x-ray), tooth contacts are checked. Your bite is adjusted until comfortable and stable contacts have been achieved. Lastly, polishing is performed with a hand piece to create smoot, functional and cleansable surfaces. For teeth with healthy nerves and bone you can expect some temperature sensitivity during drinking and eating for a up to 7 days. Typically this resolves within days. For younger people, this may take longer. If spontaneous aching or discomfort is experience contact us immediately for an evaluation.
