About esthetic appearance from the side face

- Orthodontic dentistry column -

There are esthetic lines and nasolabial angles as representative features to evaluate beauty of an appearance from the side face.

1.Esthetic line

The esthetic line is a line to connect from the tip of the nose to the protruding point of the lower jaw when looking from the side face.

For Japanese, it is said that it would be esthetic if the upper lip and lower lip are located 2mm inside from the esthetic line, but typical Japanese lips touch the E-line. The Westerners have higher noses compared to Japanese, the location of lips is 5 - 6 mm, or as the case may be, about 10mm in side of the line.

Mongoroid Negroid Caucasoid

E-line does not look good in the case of having a low nose but protruding teeth or jaw deformity.

2.Nasolabial angle

Nasolabial angle means the angle to be made from the line of the tip to the base of the nose, and to connect with the extended line from the base of the nose to the upper lip.

Typically, it is said that the angle for Japanese is 90 to 100 degrees, and 90 to 120 degrees for the Caucasoid. The angle may not look esthetic becoming large or small depending on the protruding teeth or anterior cross-bite.

Caucasoid Harf Mongoroid Mongoroid

The treatment of teeth alignment enables to improve the esthetic line and nasolabial angle.

3.Mental region

Mental region is a part of the lower jaw tip, looking from aside. It is said that the line from the lower lip to the mental region (lower jaw tip) would be more esthetic if it shapes smooth S-line rather than a liner.
