CAD-CAM In Prosthodontics

The advent of computer graphics and CAD-CAM have revolutionized dentistry. It is now possible to provide the equivalent of a cast restoration with a single appointment. Several systems are under development, each providing different characteristics and advantages. Some permit the clinician to be actively involved in the design process; others provide complete automation, freeing the clinician for other tasks. Some use technologies similar to those already used in dentistry; others draw technologies that are state-of-the-art in engineering or manufacturing but not dentistry. Some aspects, like optical "impressions," are fairly technique sensitive. Others like the DentiCAD digitizer are forgiving and easy to use. Some systems are easy to use; others require expert users. Some are initially expensive; others are relatively less so.
