Computer-Aided Design (CAD) involves creating computer models defined by geometrical parameters. These models typically appear on a computer monitor as a three-dimensional representation of a part or a system of parts, which can be readily altered by changing relevant parameters. CAD systems enable designers to view objects under a wide variety of representations and to test these objects by simulating real-world conditions.
Computer-Aided Manufacturing (CAM) uses geometrical design data to control automated machinery. CAM systems are associated with computer numerical control (CNC) or direct numerical control (DNC) systems. These systems differ from older forms of numerical control (NC) in that geometrical data are encoded mechanically. Since both CAD and CAM use computer-based methods for encoding geometrical data, it is possible for the processes of design and manufacture to be highly integrated. Computer-aided design and manufacturing systems are commonly referred to as CAD/CAM.
Unique Service Point(USP)
The development of CAD and CAM and particularly the linkage between the two overcame traditional NC shortcomings in expense, ease of use, and speed by enabling the design. Just as important, CAD/CAM gave the designer much more direct control over the production process, creating the possibility of completely integrated design and manufacturing processes.
There are basically two types of systems; acquisition only and scan and mill. Acquisition only systems allow the user to take a digital impression and send the file to a center where a model is made for a laboratory technician to make a final restoration. Alternatively, a scan and mill system allows for a restoration to be fabricated and stained and glazed in the office. This type of system provides a benefit to the patient in that only one appointment is necessary. It does however require skilled team members and additional chair time the day the restoration is made.
As with any new technology, training and a good implementation plan are critical. Each system has a unique learning curve, from the impression taking process, to the uploading of the scan, and the design of the restoration. Stepping into the digital age requires minimal computer skill and the systems are very user friendly.
It will be advisable that you have or develop drawing fundamentals and Mechanical or Minimum Know about Civil Basics.
