Preclinical Course in Computer-Aided Design and Computer-Aided Manufacturing (CAD/CAM) Digital Dentistry:...

Computer-aided design and computer-aided manufacturing (CAD/CAM) technology is an innovative digital system capable of scanning prepared teeth that are intended to receive crowns, bridges, and inlays and then effectively designing and fabricating restorations. Many dental schools are currently implementing this innovative CAD/CAM technology as part of their curricula and at University of Florida College of Dentistry we created a hands-on elective.

The 5-week course requires 2- to 3-hours of time per week for the lectures and labs. The sessions cover an introduction to digital dentistry, technology and systems evaluation, an exercise for scanning, designing, milling, and finishing a single unit ceramic restoration, and a final exam. The students also gave presentations about systems and materials used. The classroom exercises included small-group learning and class debate sessions.

In 2015, two 5-week sessions included a total of 16 participants (8 each). The overall course satisfaction from the combined two rounds was 4.7 out of 5. Comments for the course have been generally positive, indicating that the course was a successful introduction to CAD/CAM technology. Students' comments showed that they were very impressed by the new technology and interested in implementing it in their practices.

This exercise in the comparison between CAD/CAM and conventional technology resulted in a deeper understanding of digital dentistry systems and ensured that students were prepared in their clinical reasoning to apply their education in real-world decision making after graduation. By integrating this new technology in a core curriculum, preclinical, prosthodontic sophomore course and as a junior elective course, students were provided with the hands-on experience needed to utilize CAD/CAM effectively in patient care.
