FACIAL ANALYSIS
1. FACIAL TYPE:
Mesofacial Dolicofacial Brachyfacial

There are two reference lines: the horizontal line corresponds to the greatest width of the zygomatic region,
and the vertical line is the line that passes through the lowest point of the chin and the midpoint between the
eyebrows.

2. CONVEXITY:

Recto

Concave

Convex

The angle is formed by connecting the glabella, subnasale and pogonion. The proposed
normative value is 140.2º ± 4.9º for males and 138.9º ± 6.2º for females.

3. PROPORTION OF FACIAL THIRDS

Presents

Not present, increased third medium

Not present, diminished third

Superior Inferior Middle

The ratio between the middle and lower facial thirds — measured from subnasale to glabella and
from subnasale to soft menton — is 1 ± 0.08 in the normal standard.

1. 4. LIP SEAL:

Presents

Not Present interlabial

space

With the lips relaxed, there is a 1 to 3 mm space between the lower border of the upper lip and
the upper border of the lower lip.

 5. ANTEROPOSTERIOR LIP RELATIONSHIP:
Upper and lower
Upper lip in front of lip on the same Lower lip in front of
the lower lip line the upper lip

Measured by the line formed by the subnasale and soft pogonion points, the subnasale-
pogonion line (Sn-Pg’), Upper lip in front of the Sn-Pog’ line: 3.5 mm + - 1.4 mm. Lower lip in front
of the Sn-Pog’ line: 2.2 mm + - 1.6 mm.

1. 6. FACIAL SYMMETRY AT REST:

Present
Right Left
Not Present

It is the horizontal and vertical balance between the two sides,

True
i.e. proportions of size of the lateral structures to the true vertical horizontal line
line. The asymmetrical side must be indicated.

1. 7. FACIAL SYMMETRY IN MOUTH OPENING

Presents
Right Left
Not Present

It refers to the horizontal and vertical balance between the two

sides of the face, that is, the proportional sizes of the lateral
structures relative to the true vertical line. Any asymmetrical side
should be identified.

8. NASOLABIAL ANGLE

Normal Open Diminished

The angle is formed by the intersection of the base of the nose and the
upper lip. The normative values are 111.9° ± 8.4° for females and
111.4° ± 11.7° for males.

4
 9. MENTOLABIAL GROOVE

Normal

Deep

Shallow

The angle formed between the lower lip and the anterior projection of the chin. Its proposed
normative value is 124º ± 10º.

10. ZYGOMATIC PROJECTION:

Decreased Normal Increased

IIt requires simultaneous frontal and profile examination. Evaluation is performed using the
nasal implantation line, which extends from the lowest point of the orbit to the nasal wing.
Diagnosis is based on the infraorbital depression: it appears deficient in cases of maxillary
hypoplasia (resulting in a straighter line) and increased in cases of maxillary protrusion (resulting
in a line with greater angulation).

11. CHIN-NECK LINE:

Normal Increased Decreased

It is defined as the distance from the chin-neck junction to the soft tissue
of the chin. Although no precise measurement is required, a
morphological assessment of normality, excess, or deficiency is
necessary.

12. CHIN-NECK ANGLE:

Normal Open Closed

It is the angle formed between the chin and the neck. Patients with
exaggerated clockwise rotation of the mandibular joint present a closed
chin-neck angle, while counterclockwise rotation increases this angle.
