Hello.
I am Director Jo Hyuk-chan of Cleor Clinic Uijeongbu Branch.
Many people visit us after being told at the dentist that their molars are unusually worn down.
When they hear that they might have a habit of clenching their teeth at night,
it may not feel real at first, but upon reflection, they recall mornings when their jaw felt heavy
and they found themselves pressing on that area with their hands.
Teeth clenching and grinding are activities that are difficult to be aware of yourself.
You are not conscious of them while sleeping, and even when awake, you may find yourself
unconsciously clenching your jaw while focusing on a screen or driving.
As time passes with this habit, the muscles on the side of the jaw are essentially being constantly trained,
and many people discover this habit while looking for the reason why their face looks wide in photos.
Today, I will summarize what Uijeongbu Square Jaw Botox is, which muscles involved in chewing are targeted,
what its strengths are, and what you should know in advance.
What is Uijeongbu Square Jaw Botox?
👉 Uijeongbu Square Jaw Botox is a treatment that temporarily reduces the contraction intensity of the masseter muscles used for chewing and clenching,
addressing both the angular side profile and the heaviness of the jaw.
The masseter muscle starts below the cheekbone and attaches to the outer side of the angular part of the lower jawbone.
Since the attachment point is the most prominent area on the side of the face,
the thickness of this muscle is easily perceived as the width of the side profile.
If you place your hand on the side of your jaw and clench your teeth, you can immediately
confirm its location and thickness through the sensation of it bulging firmly.
There is not just one reason why a jaw looks angular.
It varies depending on whether it stems from the shape of the lower jawbone itself, an increase in masseter muscle thickness,
or a combination of changes in the skin and fat layers.
Since Botulinum toxin deals with the muscle part, the approach is different from when bone or fat is the main factor.
The Botulinum toxin used here is a protein component that blocks the release of neurotransmitters
that send contraction commands from nerve endings to muscles.
It is accurate to understand it not as a method of melting or cutting the muscle, but as a way of reducing
the amount of signal arriving at the point where the muscle receives commands.
Strengths of Uijeongbu Square Jaw Botox
👉 It approaches based on the structure where multiple muscles share the chewing motion.
It targets activities you are not conscious of, and the thickness is distributed by checking with eyes and hands.
First, the chewing motion is not handled by the masseter muscle alone.
The motion of pulling the lower jaw upward is shared by the temporalis muscle spread wide on the temple,
and the medial pterygoid muscle located inside the lower jaw, along with the masseter muscle.
The three muscles pull in different directions to create the chewing motion together.
Therefore, even if the amount of signal arriving at the masseter muscle is reduced, the entire chewing motion
does not disappear at once, and the share handled by the remaining muscles remains intact.
The basis for being able to selectively reduce the intensity of only the muscle that most significantly affects the side profile impression lies in this shared structure.
Second, it targets activities that are difficult to control consciously.
Even if you decide not to clench your jaw, that resolve does not reach you while you are sleeping.
This is why efforts to break the habit often do not succeed,and what we deal with here is not the mindset, but the physical stage where commands pass from nerves to muscles.
Since the state of reduced signal arriving at the muscle is maintained even during times when you are not conscious,
the magnitude of the force applied changes even in moments when you were clenching without realizing it.
Third, you can directly check and distribute the thickness.
The masseter muscle is just below the skin, so you can touch and confirm the range of bulging when clenching
and the difference in thickness between the left and right sides on the spot.
If you have a habit of chewing on only one side, it is common for the left and right thicknesses to be uneven,and the ability to divide and distribute based on the range confirmed by eyes and hands
is what makes it different from dealing with deep tissues inside the face.
This is also why a significant portion of the consultation time is spent on palpation.
Procedure Method and Composition
👉 At the Uijeongbu branch, Square Jaw Botox is grouped as jaw area Botox,
and the composition varies depending on the number of units placed on the left and right and which agent is used.
Since the masseter muscle is used every time you chew, the left and right thickness and strength are often different.
Therefore, even for the same jaw Botox, we do not set the same number of units for the left and right,
but divide and set them according to the left and right while checking through palpation.
Items with different target layers are placed together around the jaw.
There are separate compositions for looking at shallow facial expression muscles, looking just below the skin,
and looking at large muscles of the torso and limbs.
Square jaw is placed in the position of looking at the deep chewing muscles among these.
The thickness of the side of the jaw and chewing habits vary from person to person,
so the number of units and injection points are not fixed to one.
The timing of the next session is also determined by checking the degree to which the thickness returns.
Types of Uijeongbu Botox
👉 Since the time of day when force is applied varies for each muscle, we categorize items based on when and how long they endure.
The force of grinding teeth at night is greater and lasts longer than when awake.
Therefore, even for the same face, thickness accumulates differently for those who grind their teeth.
You may want to look into this in these cases:
Those who have been advised at the dentist about teeth grinding or clenching habits
Those whose jaw area feels heavy or firm to the touch in the morning
Those who feel their face looks wider than it actually is in front-facing photos
Those who feel that their weight has decreased but the width of their jaw remains the same
Those who want to look at the range separately from salivary gland Botox or contour injections
The principle of how Square Jaw Botox works
👉 Here, we first lower the contraction intensity. The lowered intensity leads to the thickness of the muscle fibers in turn.
The first step is the magnitude of force.
For a muscle to contract, a neurotransmitter must be released from the nerve ending and reach the receptor on the muscle side,
and toxin blocks the process of this neurotransmitter going out, reducing the amount arriving for a while.
The change where the force unconsciously applied when clenching teeth is lowered comes from here.
The next step is thickness.
The volume of a muscle is created by the cross-sectional area of each muscle fiber,
and this cross-sectional area varies depending on how strongly and how long it is used.
The property that a muscle that frequently receives heavy loads becomes thicker and a muscle that has not been used for a while
becomes thinner applies to the masseter muscle as well.
If the state where the applied force is lowered continues, the reason for the muscle fibers to maintain their thickness decreases,
and the thickness gradually changes over time.
This is the reason why it is a change that appears over a period of time, not a change completed within a few days.
The last is the returning stage.
The nerve endings recover their transmission ability over time, and the chewing force also returns to its original level.
When the usage intensity rises again, the thickness also tends to return.
Therefore, Botox is not an item finished in one go,
but is operated as an item that is continued by setting intervals while observing the condition.
Reactions that may occur and points to note
👉 Reactions reported after injection generally stay within a range that subsides within a few days.
⚠️ Precautions before and after the procedure
❓ Frequently Asked Questions (FAQ)
Q. Does it become difficult to chew food?
A. The chewing motion is shared by the masseter, temporalis, and medial pterygoid muscles, so even if the signal of one muscle is
lowered, the share handled by the remaining muscles remains intact.
Chewy food may feel more burdensome than usual at first, but as time
passes, it tends to return to the original sensation.
Q. How is it different from surgery that deals with bone?
A. The tissue approached is different.
Unlike the method of approaching the shape of the bone, it is a method of lowering the amount of signal arriving at the muscle, so no incision is
involved, and there is room for it to return as muscle function recovers over time.
Q. Does it also involve the habit of clenching teeth at night?
A. Since toxin acts on the stage where commands pass from nerves to muscles, not on the mindset,
the magnitude of the force applied changes even during times when you are not conscious.
However, since it must be distinguished from problems with the temporomandibular joint itself, if pain
persists, we recommend dental treatment as well.
Q. Can the cheeks look sunken after the injection?
A. As the muscle thickness changes, the impression of the side profile can change as well.
This is why we set the distribution more carefully if you have less cheek fat,
and we check the volume status together during the consultation.
Q. How is Square Jaw Botox different from contour injections?
A. The layer being looked at is different.
Botox lowers the contraction intensity of the muscle, and contour injections deal with the fat layer, so the direction
is divided depending on whether the cause of the concern is muscle or fat.
Q. At what intervals is it repeated?
A. We do not apply a fixed interval uniformly.
Since the timing when chewing force and the side profile return varies depending on muscle thickness and lifestyle habits,
it is natural to set the next schedule while observing that timing.
Uijeongbu Square Jaw Botox is a treatment that utilizes the structure where multiple muscles share the chewing motion
to temporarily lower only the contraction intensity of the masseter muscle, which most significantly affects the side profile impression.
Since it acts at the signal stage even during times when you are not conscious,
it can be looked at on the same axis as teeth clenching, which is difficult to be aware of,
and because the muscle is just below the skin, you can touch and confirm the thickness and left-right difference to set the distribution.
Even for the same side profile concern, the proportion occupied by bone shape, muscle thickness,
and volume status varies from person to person, so the range is not fixed to one.
At Cleor Clinic Uijeongbu Branch, we check these parts directly during consultation.
We also operate items that look at the lower face together, such as salivary gland Botox or jaw Botox,
so you can look at the range separately.
If your jaw felt heavy every morning, it would be good to talk about it comfortably.
