Dear Alumnus,

The technological advances have revolutionized the practice of dentistry on the whole. More durable, esthetically pleasing dental restorations in a single visit have been made successfully in the recent years by the advent of computer-aided design (CAD)-computer-aided manufacturing (CAM) design instead of sending the impressions out to a laboratory and temporary while waiting for the results. The dentist can now perform many common restorations including crowns and onlays. These are much more convenient for both the patient and the dentist.

CAD is defined as the application of computer and graphics software to aid the product design from conceptualization to documentation. CAM is defined as the effective use of the computer in manufacturing planning and control. CAD–CAM systems are generally comprised three parts: a scanner, a design software package, and a milling machine. All these components are used together in the digital process of creating tooth restorations like dental crowns. The digital impression of the patient's teeth is captured using an intraoral wand that is moved over the surface area of the teeth to be restored. The design software also facilitates the creation of the tooth replacement. The data are then passed on to the milling system so that the dental crown or bridge can be fabricated. This takes a few minutes to create a tooth restoration that is ready to be applied. Till date, CAD-CAM restorations have shown more than 6 years of good clinical performance. The limitations include the high cost of the machine and requirement of special skill. Despite these limitations, CAD-CAM systems will dictate the suitability of this type of restorations on an individual basis in the future.

As there is a saying that “Change always provides opportunities---to learn new things, to rethink, and to improve the way to work… Hence, it is the right time to change from conventional to digital dentistry.”
