The criteria of facial harmony
For Julien Philippe, facial beauty comes from the combination of three elements:
Form (harmony of proportions)
Smooth surface: no wrinkles, scars
The expression: sensuality and intelligence.
Our assessment is made on a face at rest, very relaxed.
From the front:
The face should be essentially symmetrical about the median sagittal plane which passes through:
The middle of the forehead
The root of the nose
The base of the nose
The philtrum
The middle of the mouth
The middle of the chin.
In the vertical direction, the lines:
Ophryaca
Bipupillary
Bicommissural
Bitragualle
Bigoniaque
Must be parallel to each other and perpendicular to this symmetrical plane.
The frontal, nasal and buccal floors should be equal.
However, slight variations in the transverse and vertical direction remain acceptable and do not change the beauty of the face.
In a balanced face the face can be long and narrow, short and wide or somewhere in between.
In profile:
The profile is the most characteristic aspect of the facial complex. Izard standardizes the study of the skin profile from photographs.
He suggests drawing horizontal and vertical reference lines. The location of the chin protrusion, in relation to these lines, determines the general shape of the profile. This will be orthofrontal, cisfrontal or transfrontal.
It is a question of appreciating the relationship of the aesthetic line with the integuments: nose, lips, chin.
The labiomental package must be located between the Simon and Izard planes.
Ricketts uses an aesthetic line which is the E line connecting the tip of the nose to the tip of the chin. The upper lip is located 2 mm behind this line and the lower lip should touch this line.
So we can have a straight, convex or concave profile.
Lips:
Their thickness tends to increase if the growth of the nose is significant.
Their length, that is to say the bicommissural width for ricketts, must be located halfway between the vertical of the wing of the nose and the vertical of the center of the pupil.
At rest, the lips are usually in contact in order to:
Protect teeth and gums.
Assist swallowing.
Retain the anterior teeth.
Smile aesthetics:
It should only reveal the free gum. If the upper lip reveals too much of the gum, we speak in this case of a gummy smile.
The teeth:
The position, shape and appearance of the anterior teeth are important in the harmony of the dentition.
For example, they will be pushed back or intruded if they are unsightly rather than if they are pretty.
The chin:
In harmony with the nose and lips. It can be flat, prominent or receding, rounded, oval or square in shape.
The aesthetic objectives of orthodontic treatment :
To proportion the floors or at least not to aggravate an existing disproportion.
Move the maxilla back or move the mandible forward or vice versa.
Place the incisors according to the patient ‘s aesthetic interest .
The criteria of facial harmony
Early cavities in children need to be treated promptly.
Dental veneers cover imperfections such as stains or cracks.
Misaligned teeth can cause difficulty chewing.
Dental implants provide a stable solution to replace missing teeth.
Antiseptic mouthwashes reduce bacteria that cause bad breath.
Decayed baby teeth can affect the health of permanent teeth.
A soft-bristled toothbrush preserves enamel and gums.
