Abstract:

Purpose: Teaching pre-doctoral students state of the art technology, using CAD/ CAM dentistryTraditional training in the fabrication of indirect restorations consists of numerous tedious steps, such as learning how to take and pour impressions; trim dies, prepare, invest and burn out wax patterns; cast inlays, onlays and crowns; and finally finish these for placement in patients’ mouths. Every step had the possibility of introducing errors. Even with the introduction of technical advances, errors still persisted. The explosion of computer generated methodologies, and the accompanying new materials, has largely eliminated the tedium and inaccuracies. We at NYUCD successfully introduce our students to one of these technologies (the CEREC® CAD/CAM unit), beginning in their second year as part of an Esthetic Dentistry course.
The CEREC (ceramic reconstruction) system constructs crowns, onlays and inlays out of ceramic or composite blocks. We teach the students to prepare and fabricate indirect restorations on typodont teeth, using the Bluecam impression technique. Each student is trained to take an optical impression and use their own computer to design different types of restorations. Students are required to complete additional assignments using the most recent software available. The students also gain invaluable experience by preparing, designing and cementing CAD/CAM restorations on their patients when indicated.
The NYUCD program introduces its students to a methodology of constructing permanent, high-quality, durable restorations during only one clinic visit. This allows them to complete their clinical requirements. It engages our students in the use of a new technology that results in greater efficiency and less stress to both the patient and the clinician.
