Why is our clinic using CAD-CAM? It is an exciting area of dentistry that is growing in different areas every day. It offers many advantages to the dentist and the patient. The process is very precise and can reduce adjustment time. There are no temporaries and no need for a second visit.
CAD/CAM is an acronym for computer-aided design/computer-aided manufacturing. The CAD portion of the process involves the use of a scanner to create a digital model of the preparation. Once the model has been generated on a computer workstation, the restoration can be designed by the doctor, an assistant, or a lab technician.
The computer program displays 3-D custom images of teeth and gums, allowing dentists to precisely design the tooth restoration with functional and esthetic characteristics in mind. Once the restoration has been designed by the computer and cosmetic dentist, the information is sent to a sculpting machine (milling), which creates the restoration to the exact specifications of the design through CAM. There is no need for impression taking, temporaries or unnecessary reduction of healthy tooth structure. It means that in just 2 hours you can have a crown!
The technology is so precise that dental restorations made by CAD/CAM often fit better than those made by hand in a dental lab. Patient satisfaction is being increased simply because you can have your tooth repaired in a single day, instead of having to return for repeat appointments. Spending time in the dentist’s chair is low on most people’s priority lists, and CAD/CAM dentistry technology is helping you move on faster than ever before.
Main advantages of CAD/CAM technology:
- Positive patient experience
- Accuracy of shape prevents gapping between tooth crowns and surrounding teeth
- Immediate 3D images remove the need for taking time-consuming impressions of teeth
- Allow dentists to scrutinise their preparations carefully
- Offers instant display and feedback
- Cuts the number of the patient’s visits to one
- Eliminates these steps: tray selection, mixing/dispensing materials, disinfection, mailing impression to/from laboratory
- CAD/CAM restorations are better-fitting, more durable and more natural looking (multi-coloured and translucent, similar to natural teeth) than previously machined restorations.
- Environmentally friendly
