4. Make sure occlusal rim is parallel with the Ala tragal pain

Question 3

What do we check for when we are recording the occlusion of the lower rim

Answer 3

Adjust height for correct oVD

Question 4

What do we check for when we are recording the occlusion of both occlusal rims together

Answer 4

1. Mark on the mid line and premolar lines

2. Guide patietn to retruded position and seal with blu mousse

Question 5

State the ideal nano labial angle

Answer 5

90-110 degrees

Question 6

What can we do to increase lip support on an upper occlusal rim

Answer 6

Use was

Question 7

Use fox occlusal plane guide

Question 10

How do we ensure the upper occlusal rim is parallel to the alar tarsal plane

Answer 10

Use fox occlusal plane to compare the line running between the trigs and widest part of nostril with the denture
(can use a wax knife to visualise the alar tragal plane )

Question 11

How do we change the ordination of the upper record rim if it is not parallel with the alar tragal line

Answer 11

Add or remove wax from the poster part of the rim in a wedge shape
(we want to retain a flat base to the rim)

Question 12

What should the free way space be

Answer 12

2-4mm

Question 13

What is OVD

Answer 13

Occlusal vertical dimension

Question 14

What is RVD

Answer 14

Retruded vertical dimension

Question 15

How do we measure OVD and RVD

Answer 15

Using willis gauge

Question 16

When do we seal the registration with blu mousse

Answer 16

At the end wehn both upper and lower model are in the mouth and patent is in the rtetruded position

Question 17
