The term CAD/CAM dentistry is literally a shortening of Computer-Aided Design (CAD) and Computer-Aided Manufacturing (CAM) aka "one-visit-crown," in dentistry. The CAD/CAM machine provides the dentist with dental crowns, which are milled from blocks of white composite resin or porcelain, matching the shade of the restored tooth. Once the treated tooth is shaped and prepared, an image is taken of this defected tooth. The image then provides the data for a computer and the software is used to create a porcelain or resin composite piece for the defect, essentially creating a virtual dental crown.
The CAD/CAM dentistry software then sends this virtual data to a milling chamber in the lab where the dental crown is carved out of a solid block of composite resin or porcelain. Our standard of quality, here at Kneib Dentistry, is the highly esthetic, high strength e.Max porcelain ceramic crown. The resultant dental crown can then be adjusted in the patient's mouth and cured/bonded in place. Following acid etching of both the underside of the crown and the topside of the tooth itself (which increases the surface area on both opposing surfaces), composite resin materials are then used to fuse the resultant crown to the tooth, completing the dental crown procedure.
What is a porcelain ceramic crown?
These dental crowns are made of both porcelain and ceramic materials, which provide a very close match to the color of your natural teeth. They are also a great choice for patients who have allergies or general sensitivity to metal.
How is CAD/CAM used in dentistry?
CAD and CAM refer to Computer Aided Design and Computer Aided Manufacturing, respectfully. This type of dental technology allows dentists to make custom-fitting dental crowns that will perfectly adhere to your teeth. These crowns are made of resin, ceramic, and porcelain.
What are the benefits of CAD/CAM technology in dentistry?
CAD/CAM technology gives patients the benefit of faster dental service for tooth restorations. With this technology, dentists can create highly accurate copies of dental crowns right in the office! Otherwise, patients may have to wait weeks while this process is performed in an external lab.
What is dental milling?
Dental milling machines are included in CAD/CAM technology. These machines take digital scans and impressions in order to mill, or "grind", resin and porcelain materials into dental fixtures, such as dental crowns.
Can you change the color of a dental crown?
You cannot change the color of an existing crown. You also should refrain from bleaching or whitening your crown in any way. If you do desire a crown with an updated or enhanced color, visit your dentist to talk about installing a new crown with a whiter color.
