Today, Xiaobian chewed beef jerky.

After biting half of it, I learned that the mandible can grow to 40 years old?

The beef jerky in my hand suddenly doesn't smell

Then I began to think of Pearl Ozawa.

In the comments, a large group of people shouted that the fat is not the face, but the mandible has grown up.

Some even asked, "Why cut bones, cheeks?".

So is the mandible crazy? Why can it grow so long? The older you are, the shorter and wider your face will be. Is it because the mandible eats too well?

Today, I will solve the mystery of mandible and its role in facial contour

Before we begin, let's ask a question. Why do many online celebrities not look so good on the screen?

The facial features are the same, but I always feel something is wrong. A large part of the reason is that the outline has changed.

In fact, the adjustment of the filter contour and the adjustment of the facial features are much larger. It can shrink the face and accept the chin, but most of the time, I only care about whether the eyes are big enough.

The superior contour is also the reason why even if the model does not pursue more bleaching, the photos still make people feel comfortable and do not lack beauty.

The influence of the face on the contour is greater than that of the lower part of the face.

The male guest of the Korean plastic reality show changed his face, which was totally different.

Although the nose and eyes are fine tuned, it can be seen that the jaw changes have a great impact.

This is because the upper part and middle part of the face are relatively stable, and the lower part of the face is easy to change the position of the face

Many child stars look cute when they are young, but their temperament is completely different when they grow up, mainly due to the development of their faces.

The artists who grow up in the same proportion are praised. The lower part of his face is relatively large, and has not changed much when he was young.

It can be said that the lower part of the face is the influential part of the side.

The shape and bone phase of the mandible are mainly determined by the mandible and chin. The skin stage was affected by masticatory muscles and mandibular chin fat.

Generally speaking, the length, angle and soft tissue adhesion of the mandible will affect the length and width of the face, as well as the smoothness of the lower part of the face.

Chin from lip edge to chin edge

It affects not only the length and width of the lower part of the face, but also the depth of the nose and lips

Today, I will discuss how the mandible affects facial contour

Factors affecting facial mandible

When it comes to the broad impact, the first thing to think about is the hypertrophy of the masseter muscle.

This is indeed a more important factor, especially in adolescence, which may be due to chewing more bubble gum.

But for my oriental people, masseter hypertrophy is not the main reason. More likely, this is due to excessive valgus of mandibular angle.

So how to judge whether the mandibular angle has valgus mainly depends on the width of the mandibular angle.

Conversation is the distance between two mandibular angles

Some time ago, I raised my chin to take photos and measure the folding degree of the face. In fact, it can help you see the width of your chin.

The average width of the mandible is 9.5~11.5 cm.

If you don't exceed this distance in the future, it's hard to say your face is wide.

Mandibular factors that determine facial length

What you may not have expected is that the factors that affect the length of the lower part of the face also have the shadow of the masseter muscle

The influence of masseter muscle is mainly to change the angle of mandibular angle

The masseter and medial pterygoid muscles pull the mandible through muscle contraction.

The stronger the masseter muscle, the greater the strength to tighten the mandible, and the smaller the mandibular angle

Once the mandibular angle is reduced, the height of the chin will be limited.

To put it bluntly, the jaw angle is small and the chin is low.

The ideal mandibular angle should be greater than 110 degrees. If it is less than this degree, the face may be short and wide.

This depends on the height of the mandibular ramus.

The height of the mandibular branch, that is, from the ear root to the mandibular angle, the length of the vertical line is 1-2 cm. Too long or too short will lead to the problem of long face.

Generally speaking, the development of mandible in late adolescence is generally stable. In other words, when I was 17 or 18 years old, the length and width of my face were almost fixed.

Is it true that the mandible can grow to 40 years old?

This is true, but the situation is different.

After entering the stable period, the mandibular development reaches the adult stage, almost between 17 and 25 years old.

The mandible grows 3~6 mm in males and less than 1 mm in females.

Especially for women, if family members do not have sustained jaw growth.

Therefore, rather than worrying about the continuous growth of the mandible, it is better to worry about the absorption of the mandible.

Yes, as we grow older, we lose calcium.

The height and length of the mandible will be shortened. The lower part of the face becomes shorter, the mandibular edge is unclear, and the mandibular angle increases.
