Q

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.

A

underlying skeletal

18
Q

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

A

•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.

19
Q

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

A
  • Glabella.
  • Sub-nasale.
  • Pog.
20
Q

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

A

disproportion

21
Q

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?

A

Does not indicate which is issue

22
Q

What are the 3 terminologies used to describe profile type?

A

Convex
Straight
Concave

23
Q

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.

A

convex

24
Q

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.

A

concave

25
Q 
•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)
A

Facial type

26
Q

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

A

perpendicular

27
Q

What are the 3 facial types?

A
  • Orthognathic. (Mesognathic)
  • Retrognathic.
  • Prognathic.
28
Q

Most of the time lips get their support from the _______

A

incisor teeth

29
Q

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

A

relaxed.

30
Q

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

A

True

31
Q

______ 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)

A

Lip prominence

32
Q

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

A

prominent; retrusive.

33
Q 
Because lip prominence is in the 
context of the relationship of the lips to 
the nose and chin, it can be helpful to 
draw the \_\_\_\_\_\_ from the 
Pro-nasale to Pog.
A

E-line (esthetic line)

34
Q

Because lip prominence is in the
context of the relationship of the lips to
the nose and chin, it can be helpful to
draw the E-line (esthetic line) from the
____ to _______.

A

Pro-nasale to Pog

35
Q

The guideline is that the lips should be _____ or _______ of the E-line.

A

on

or slightly in front

36
Q

In the extreme case, ________ can produce ideal alignment of the teeth
instead of severely crowded incisors, at the expense of lips that protrude and
are difficult to bring into function over the protruding teeth.

A

incisor protrusion

37
Q

In the extreme case, incisor protrusion can produce ideal alignment of the teeth
instead of severely crowded incisors, at the expense of lips that ______ and
are difficult to bring into function over the protruding teeth.

A

protrude

38
Q

In the extreme case, incisor protrusion can produce ideal alignment of the teeth
instead of severely crowded incisors, at the expense of lips that protrude and
are difficult to bring into function over the protruding teeth.

-This called _______ meaning simply that in both
jaws the teeth are protruded

A

bimaxillary dentoalveolar protrusion,

39
Q

What 3 facial appearances are seen in bimaxillary dentoalveolar protrusion?

A
  • Excessive separation, more than 3-4mm, of the lips at rest (lip incompetence).
  • Excessive effort to bring the lips into closure (lip strain).
  • Prominence of lips in the profile view (E-Line).
40
Q

The inclination of the _______ to the
true horizontal can determine the lower anterior
facial height and posterior facial height.

A

mandibular plane
