Prof. Dr. Wolf Dieter Muller from Zurich University came to visit Riyadh Colleges of Dentistry and Pharmacy last November 4, 2014 and gave an extensive lecture on the use of CAD-CAM in dentistry and prosthodontics. CAD-CAM (computer-aided design and computer-aided manufacturing) refers to computer software that is used to both design and manufacture products. CAM software uses the models and assemblies created in CAD software to generate tool paths that drive the machines that turn the designs into physical parts. CAD/CAM software is most often used for machining of prototypes and finished parts.

Dr. Muller, thus, discussed the use of the CAD-CAM technology to improve the design and creation of dental restorations, especially dental prostheses including crowns, crown lays, veneers, inlays and onlays, dental implant restorations, dentures and orthodontic appliances. He explained that CAD/CAM complements earlier technologies used for these purposes by any combination of increasing the speed of design and creation; increasing the convenience or simplicity of the design, creation, and insertion processes; and making possible restorations and appliances that otherwise would not have been feasible. CAD-CAM, he said, is also meant to reduce unit cost and make affordable restorations and appliances that otherwise would have been prohibitively expensive.

Prof. Muller’s three-hour lecture at the auditorium of RCsDP was well-attended. Present at the lecture were the Rector, the deans and faculty of the College of Dentistry, postgraduate students, interns and undergraduate students in dentistry and other guests.
