This article from Henry Schein has a very good outline of the CAD CAM process and an interesting and I think realistic look at ROI for this very exciting and yet admittedly very expensive technology. Whetever else can be said about the technology the simple fact a patient does not have to return for a second appointment is HUGE.
Practice overhead typically 60%–70% makes up the majority of “costs” of any dental procedure and being able to complete a procedure in one appointment that previously took two appointments, with about the same amount of chairtime, automatically saves the practice time and money. With no second appointment, there is no expense for greeting, seating, patient preparation, operatory turnover or the possibility of second-visit cancellations
