midterm review

Question 1

zirconia framework are fabricated by

Answer 1

CAD/CAM

Question 2

pressed on zirconia ceramics means

- general

Answer 2

zirconia framework then pressed on ceramics to that

Question 3

when fabricating an FPD from 3-X-X-6, this FPD should…

Answer 3

CANINE GUIDANCE
- b/c reasons why they are best at accpeting forces

only time not doing this is if they are implants

Question 4

why canine guidance

Answer 4

accept horizontal forces that ocur during eccentric movemetns in addition to disarticulating the posterior teeth

longest and largest that are surrounded by dense compact bone – tolerates forces better

fewer muscles are active when canines contact – lower levels of muscular activity - will decrease the forces to the dental and joint structures

Question 5

pt has class II div II who is missing 4 and 5 the FPD that is designed from 3-x-x-6 can …

Answer 5

TALLER CUSPS THAT will not cause pre mature contacts due to steep anterior guidance

deep bite
steep anterior guidance

Question 6

group functio harder to restore

Answer 6

yes

Question 7

limited missing teeth and sending to lab for fabrication what does not need to be included in rx

Answer 7

CR wax recrd – because they have MIP!!

DOESNT WANT THE WHOLE ARCH SENT

Question 8

Once something is between the teeth in occlusion

Answer 8

no longer MIP - no longer the best fit of occlusion

Question 9

when pt. protrudes mandible, the potential for disclusion of the posteiror teeth will INCREASE with:

Answer 9

steeper anterior guidance

steeper condylar guidance
- separate even more

Question 10

steep curve of spee implication?

Answer 10

higher in back – like compensating curve
