midrerm cAD CAM

The very first scanner was manufactured by - Nobel

Biocare (non-chariside)

a. First in office chairside scanner was Sirona

2. CAM refers to - CNC where software dictates the movement of a factory tool and machinery**

3. How does rapid prototyping help DT - all above: each case is unique, no mass production, unique, specific design match to specific patient, more efficient

4. Which of the following is not a finishing tech required for CAD/CAM - printing

a. Polishing, glazing, staining, and fitting are finishing techniques

5. Which restoration can be fabricated using milled/printed

PMMA - temporary restoration **

a. You can mill or print a temp crown out of resin or a block of PMMA

6. Ceramic layering is completely eliminated with the use of CAD/CAD - false (never will be completely eliminated)

7. In CAD/CAM dentistry, which of the following is not an indication for using milled zirconia - models

a. Zirconia can be used for single unit crowns, implants, substructures, and bridges

8. Which of the following is considered an advantages of chairside CAD/CAM technology - no physical impression taking required

9. When considering scanning in a lab, which light do current scanners use - structured light

10. In CAD/CAM day to day C&B manufacturing requires a scanner with an accuracy level of - 10 microns (higher detail/accuracy needed for margins and etc)

11. Intraoral scanners are becoming more common in dental office, its likely because - digital impression is more accurate

12. Lab scanners are differentiated by varying feature/factor, which is not considered a differentiating factor - the size

13. Partial denture frameworks can be - all above: milled, printed, and done with analogy techniques

14. Which material cannot be used for FC single crown restoration in CAD/CAM dentistry - wax

a. Can be made of alloys, zirconia and lithium disilicate

15. Which of the following best describes the digital workflow in CAD/CAM dentistry - Scan designed, mill finish deliver
