• inter pupillary line
• ala tragus line
• canthus tragus line
• naso labial sulcus
• vermillion border
• labio mental sulcus

Question 19

Ala-tragus line 👃

Answer 19

• It is an imaginary line extending

• which is used for determining the occlusal plane of the denture. (Post. part)

Question 20

Naso labial sulcus 👄

Answer 20

It is a depression, which extends from the side of the nose downwards and backwards.

# It becomes deeper with age and with the loss of teeth especially the canines.
# It can be restored through
- proper positioning of ant teeth of denture
- proper contouring of upper denture flange.

Question 21

Philtrum

Answer 21

• a diamond shaped area located at the center of the upper lip
• w/ anterior teeth loss it becomes flattened
• replacement of missing teeth should restore its normal shape.

Question 22

Vermillion border

Answer 22

• after extraction of ant teeth, supporting alveolar bone is resorbed
• amount of vermilion border of upper lip is reduced.

Answer 23

• Inflammation + drooping of saliva from the angle of mouth Is cld “Angular Cheilitis”
which may be due to:

2. Denture with low vertical dimension
3. Vitamin B12 deficiency

Question 24

Modiolous

Answer 24

• a depression below + D to corner of mouth
• with loss of teeth it will become flattened.
• replacement of teeth should restore its normal shape.

Answer 25

• Class 1 (Normal Condition)

curvature shows acute angle, mand retruded
• Class 3

Question 31

Preservation of the remaining tissue structure:

Answer 31

• The alveolar process that developed w/ the teeth for the purpose of supporting them, resorbs to a varying extent after their loss.

• W/ loss of teeth, the TMJ r subjected to continuous strains bc the mandible closes in abnormal positions.

Question 32
