Reading for 10-3

Question 1

At the wax try-in appt it is easier to make adjustments why?

Answer 1

• teeth are still in wax

- after they are set, it is nearly impossible to correct

Question 2

If retention is a problem during the try-in appt, what can you use to make sure the try-in will stay?

Answer 2

-adhesive

Question 3

If there is contact when in VDR, how do you decrease VDO?

Answer 3

-remove posterior teeth and create new CR record if desired decrease is greater than 2mm

Question 4

If you have to create a new CR record in order to get correct reduction of VDO how does your mounting need to change??

Answer 4

-remount on articulator

Question 5

If there is too much interocclusal distance, what is the next step?

Answer 5

-create new CR record, no need to remove teeth

Question 6

If you are within 2mm of being correct, can you make the correction on the articulator?

Answer 6

• yes

- studies have show a negligible error would be present from making this minor change

Question 7

How may a class II skeletal relationship affect the clearance of the try-ins?

Answer 7

-may have what seems to be excessive vertical and horizontal clearance due to normal relationships of the residual ridges in that skeletal position

Question 8

How may a class III skeletal relationship affect the clearance of the try-ins?

Answer 8

• may exhibit almost no interocclusal distance during speech

- this must be taken into account when evaluating function of the prostheses

Question 9

If using wax to take verification record, what temp must the denture be heated in water to soften the wax?

Answer 9

-130*F

Question 10

What is the verification record used for?

Answer 10

-to determine that the horizontal position of the mounted dentures are correct

Question 11

What kinds of occlusal schemes require eccentric records?

Answer 11

-complex occlusal schemes

Question 12

What are eccentric records?

Answer 12

• protrusive position records
• lateral position records
• captures relative angle of the articular eminence as the condyle travels down the slope

Question 13

Lateral position records are best taken at what stage?

Answer 13

• when teeth are present
• allows for adjustments to be made before processing and also will provide for proper articulator setting for the insertion or placement appt.

Question 14

Midline, shade and other esthetic factors, such as individual tooth position preferences, diastemas and personalized esthetic concers should be evaluated and corrected before what?

Answer 14

-patient review of wax trial insertion

Question 15

What other considerations need to be done at the try-in appt.?

Answer 15

• custom gingival denture base shade selection

- sign consent form

Question 16

If the new verification record does not match the original record, what do you do?

Answer 16

• make a third (as a tie breaker)
• remount to either the second or first CR record based off of whether or not the third matched the first or second CR record
