Study of facial beauty for a mouth rehabilitation

Beauty is a subjective concept that depends on many factors such as ideology, age, culture or religion, ethnicity or media, among others. Still, the Egyptians introduced the study of facial beauty based on lines of horizontal and vertical reference, which determine the symmetry and harmony of a face.

Thus, analyzing the proportions of the face is very important to fix a mouth, both dental veneers and crowns, as these reference lines allow you to have a certain space so that the mouth is well with the rest of the face from view of dental aesthetics.

Proportions facial beauty

To analyze the patient 's face from a front view, three horizontal lines are drawn:

• Interpupilar: passing through the center of the pupil and is the horizontal reference line, ie, the other horizontal lines should be parallel to this.
• Intercommissure: passes through the corners of her mouth.
• Interorbital: it goes through eyebrows.

From the vertical point of view, the midline passes through the glabella ( the space between the eyebrows), the nose, philtrum (space between the upper lip and nose) and the tip of the chin. The dental specialists say that the more focused and is perpendicular to the interpupillary line, the greater the proportion in the face.

Proportion into a smile

To get a nice harmony in the patient's smile, the most important thing is that there is a parallel between the bite plane, the contour of the gum and pupillary line.

Another important to get a nice smile and proportionate with the rest of the face factor is that the lower third of the face, ie, mouth, be divided into three equal parts:

• Superior lip
• lower lip
• Chin

In addition, the lower third should be the same size as the other two thirds of the face to make it more proportionate.
