CAD/CAM Crowns - Digital Impressions
Our office has invested in the PlanScan system for the in-house fabrication of all-ceramic dental crowns. This is a CAD/CAM (computer aided design/computer aided manufacturing) system that allows us to take digital impressions of the prepared tooth and then use computer software to create a customized crown that is exactly right for the specific tooth in that particular patient's mouth. The crown is then milled (cut) out of a block of ceramic in our PlanScan mill, followed by the application of stains and glazes to further customize the crown, and finally fired in a very hot oven (like a kiln) to finish the crown and make it shiny, tooth-colored, and strong.
For your crown visit, there is typically no need for any gooey impression materials to ever be placed in your mouth. Our educated staff will use a digital scanner (small wand) to obtain the digital impression which gives the computer all of the necessary information of the prepared tooth, the opposing teeth, and the way that your teeth bite together. The scanner uses LED technology to capture the anatomy and you can even watch the scan appear in real-time on the computer screen. Most patients agree that digital impressions are significantly more comfortable than the typical methods of gathering dental information with bad-tasting impression materials!
