CAD – CAM is a short form for Computer-aided design/computer-aided Milling. CAD – CAM technology helps dentists and dental lab technicians to fabricate precise shapes and sizes for dental restorations like crowns and bridges. It can also fabricate inlays and onlays. With this technology it helps to create a durable, esthetic, well-fitted single and multiple tooth restorations in a more efficient manner and also in quick time.
Steps in fabricating CAD/CAM
The first step is tooth preparation. Later, a Digital impression of the dental arch is taken so that sends the prepared tooth’s exact digital measurements to a computer.
Next, the dental lab technician designs the size and shape of the tooth restoration using a computer. The CAD – CAM screen displays a 3-D image of the teeth and dental arch, allowing your dentist to draw a precise design for the required restoration of the tooth. A ceramic block, specific tooth coloured is mounted into the CAD – CAM machine, the milling chamber, crafting the ceramic material into a genuine replica of the tooth to be restored.
Computer Aided Design and Computer Assisted Milling (CAD – CAM) invariably eliminates time delay for the traditional fabricating process and also which occur due to human error.
