Question 6

articulating pater

Answer 6

1) 0.04 slide in

check margins precementation

Answer 8

1) use explorer
2) master cast and sectional cast
3) drag for no overhand and ledges
- or open margin

Question 9

check occlusion

Answer 9

1) on the mastercast first
- then try it in the mouth (can have small changes)

Question 10

check contours

Answer 10

1) within a quality lab, minimal adjustments necessary
- you can have it reglazed

Question 11

benefits of not numbing patient

Answer 11

1) they will be able to tell if it is fitting right
2) however, they may be uncomfortable during cementation

Question 12

CIMOE

Answer 12

C
- interproximal contact
I
- internal fit
M
- margin
O
- occlusion
E
- esthetics

Question 13

C

Answer 13

1) visual
2) floss intensity
- may not be accurate
- silk, nylon, plastic
- twisted, non twisted, waxed, non waxed
3) articulating paper
- intensity, size, location

• usually contacts prevent seating

Question 14

contact types

Answer 14

1) idea
- waxed floss passes with resistance
2) open
- no resistance with floss
- SEND BACK

- minimal resistance
- may need to send back
4) tight contact
- make adjustments

Question 17

finshing and polishing burs

Answer 17

1) various head sizes and various grids

- PVS is for ceramic crowns (ADJUST THE PREP TO NOT THIN THE RESTORATION)

Question 20

M

Answer 20

1) any discrepancy in the junction of prep and restoration can lead to poor adaptation
- short, over or irregularities

Question 21

acceptable margins

Answer 21

- 017 explorer says its good
2) if open unacceptable
- send to back to lab or reprep and get a new impression
3) if there is closed margin but under extended
- send back to lab
- if it is slight, might be ok to cement
