Smile Line:

Question 16

________ is the space between upper posterior

teeth and the cheeks.

Answer 16

Question 17

A careful examination of the facial profile yields the same
information, in less detail for the _______________
relationships, as that obtained from analysis of lateral
cephalometric radiographs.

Answer 17

underlying skeletal

Question 18

The three goals of facial profile analysis are approached in three
clear and distinct steps:

Answer 18

•Establishing whether the jaws are proportionately positioned in the
anteroposterior plane of space.
•Evaluation of lip posture and incisor prominence.
•Reevaluation of vertical facial proportions and evaluation of
mandibular plane angle.

Question 19

Connecting what 3 landmarks on the face creates the profile of
that person?

Answer 19

• Glabella.
• Sub-nasale.
• Pog.

Question 20

Profile convexity or concavity results from a ______ in
the size of the jaws, but does not by itself indicate which jaw
is at fault.

Answer 20

disproportion

Question 21

Profile convexity or concavity results from a disproportion in
the size of the jaws, but does or does not by itself indicate which jaw
is at fault?

Answer 21

Does not indicate which is issue

Question 22

What are the 3 terminologies used to describe profile type?

Answer 22

Convex
Straight
Concave

Question 23

A ______ profile:
•Indicates a Class ll jaw relationship, which can result from either a maxilla
that projects too far forward or a mandible too far back or combinations.

Answer 23

convex

Question 24

A ______ profile:
•Indicates a Class lll relationship, which can result from either a maxilla that
is too far back or a mandible that protrudes forward or combinations.

Answer 24

concave

Question 25

``` •A line that passing through the soft tissue Nasion to measure the position of the chin. •This line is perpendicular to FH and ideally should passes through the soft tissue Pog. (0 +2mm) ```

Answer 25

Facial type

Question 26

This facial profile line is ______ to FH and ideally should passes through the soft tissue Pog. (0 +2mm)

Answer 26

perpendicular

Question 28

Most of the time lips get their support from the _______

Answer 28

incisor teeth

Question 29

Lip posture and incisor prominence should be evaluated by viewing the profile with the patient’s lips _____

Answer 29

relaxed.

Question 30

T/F: In evaluating lip protrusion and retrusion, it is important to keep in mind that everything is relative. •Nose. •Chin. •lips.

Answer 30

True

Question 31

______ is evaluated by observing the distance that each lip projects forward from a true vertical line through the depth of the concavity at its base (soft tissue points A and B)

Lip prominence

Question 32

If the lip is significantly forward from this line, it can be judged to be ______; if the lip falls behind the line, it is ______

Answer 32
