What is CAD/CAM Dentistry?
CAD/CAM Dentistry is short for “Computer-Aided Design and Computer-Aided Manufacturing” in dentistry. This area of dentistry utilizes CAD/CAM technologies to produce different types of dental restorations with precise shapes and sizes for dental restorations, including crowns, crownlays, veneers, inlays and onlays, fixed bridges, dental implant restorations and orthodontic appliances.
Dentists use CAD/CAM technology to provide patients with durable, well-fitted single and multiple tooth restorations in a more efficient manner than traditional lab-fabricated restorations. This technology allows a typical two-visit tooth restoration to be accomplished in just one visit.
CAD/CAM dentistry designs the specific anatomical features, size and shape of a tooth restoration, which is unique for each patient, on a computer. The CAD/CAM computer screen displays a 3-D custom image of your teeth and gums, allowing your dentist to use a cursor to draw the precise design of the tooth restoration. This machine creates the restoration through a milling chamber that makes the tooth-like ceramic material into a precise replica of the drawing.
The Advantages of CAD/CAM Technology
There are a number of advantages of using the CAD/CAM technology in the dentist’s office. Each advantage is designed to give the patient the quickest and most precise treatment possible, to minimize the time and discomfort normally associated with certain dental procedures.
No more molded teeth impressions needed. If the CAD/CAM technology is located in your dentist’s office, dental technicians no longer need to make uncomfortable molds of your mouth and teeth. The computer aided dentistry cuts this step out since measurements are made with the CAD/CAM technology. This also frequently eliminates the need for a return visit to the office for a permanent restoration.
Decreased risk of infection, disease, and shifting teeth with crowns. Accuracy is important in creating the initial tooth preparation and impression for creating the crown. A crown that fits poorly can create both a higher rate of infection and disease because debris may lodge in open spaces and cause problems. Teeth also shift easier when a crown is not fitted properly. CAD/CAM technology creates a precise a fit for crowns that minimize these issues.
Porcelain tooth restoration offers natural looking tooth repair. In the past, providing a type of stable tooth restoration was nearly impossible without some form of metal material. Today's porcelain ceramics work very well in the CAD/CAM milling chamber, providing strength, durability, and a more natural, attractive look.
Biogeneric Engineering in CAD/CAM
Biogeneric engineering creates a custom fit crown that looks at your other teeth to make as precise a fit as possible. This is used on a tooth that is either broken or has a large filling. This technology takes multiple measurings and calculations of a good tooth and creates dimensions and calculations for a tooth needing a crown. This helps create a tooth that is very similar to your other teeth. In the end, you are left with a crown that is as much like your other teeth as possible.
Dental technology and the introduction of CAD/CAM has changed the way dentistry is done today. Routine dental procedures, such as crowns, are done in a fraction of the time with a better fit than ever. Not only does this cut down on time spent in the dentist’s chair, it also reduces dental complications, such as infection and shifting teeth. CAD/CAM dental technology is the future of a quicker and more precise dental experience.
