Checkpoints for a Beautiful Face

Two-Jaw Orthodontics, Non-Surgical Two-Jaw Treatment

Beauty Created Through Small Facial Shape Changes

A butterfly’s small flap of its wings

can even cause a typhoon on the other side of the world,

as the saying “the butterfly effect” goes.

It means that tiny changes, small differences, and minor events

can bring about unexpectedly huge results or ripple effects.

Even a small change in facial shape

can sometimes produce a big effect, like the butterfly effect.

Protruding mouth

Underbite

Receding chin

For people with these facial types,

what kind of small changes can be made?

✿ Checkpoint ✿ Two-jaw surgery? Two-jaw orthodontics?

Non-surgical two-jaw treatment refers to

orthodontic treatment that can be received at a dental clinic,

and it can induce changes in facial shape

by guiding changes in the position of the mandibular condyle.

Of course, it cannot create the same dramatic change

as two-jaw surgery performed by a plastic surgery clinic.

Because non-surgical two-jaw treatment induces only positional changes in the skeleton

without changing skeletal size,

if the skeletal structure itself is large

and its position is significantly deviated from the normal position,

functional improvement may be difficult

even with non-surgical two-jaw treatment alone.

This type of non-surgical two-jaw treatment is suitable for cases in which

the problem lies more in the teeth and oral structure than in the skeleton itself,

and where the condition is considered too much for surgery,

such as a protruding mouth, underbite, or receding chin.

A protruding mouth is usually

classified as Class 1 malocclusion.

A protruding mouth caused by protruding teeth

creates facial shape changes by moving only the anterior teeth backward

into the available space in the dental arch (extractions may be performed if there is insufficient space).

A protruding mouth caused by protruding gums

creates facial shape changes by using mini implants called screws

to move both the anterior teeth and the gum bone backward together.

Non-surgical two-jaw treatment for a protruding mouth

can make the mouth that was jutting forward because of the teeth or gums

move inward,

which may create the effect of a slimmer face.

✿ Checkpoint ✿ Class 3 malocclusion correction

An underbite is usually

classified as Class 3 malocclusion.

An underbite, also called reverse occlusion,

as the name suggests, is a condition in which

the lower jaw teeth are positioned ahead of the upper jaw teeth.

By applying the maxillary retraction used in protruding-mouth correction

in reverse to mandibular retraction,

it creates changes in facial shape.

Non-surgical two-jaw treatment for an underbite

may make the jaw appear shorter

as the mouth posture changes from one where the lower teeth covered the upper teeth.

✿ Checkpoint ✿ Class 2 malocclusion correction

A receding chin is usually

classified as Class 2 malocclusion.

A receding chin, also called deep bite,

occurs when the lower jaw is excessively retruded

or the upper jaw is excessively protruded,

and it may also be accompanied by snoring or teeth grinding.

By appropriately applying maxillary retraction used in protruding-mouth correction

and mandibular retraction used in underbite correction,

or by applying them differently depending on the cause of the receding chin,

it creates changes in facial shape.

Non-surgical two-jaw treatment for a receding chin

can create the effect of revealing the jawline

as the mouth posture changes from one where the upper teeth excessively covered the lower teeth.

As you can see, to carry out two-jaw orthodontics without surgery,

accurate diagnosis and cause analysis by the medical team,

along with a perfectly tailored treatment plan,

must come first in order to lead to beautiful results.

Just as malocclusions that can be improved with non-surgical treatment should not be forced into surgery,

the opposite is also true: malocclusions that can only be improved with surgery

should not be forced into non-surgical treatment.

Convincing predictions of facial shape changes,

a direction that considers the patient's facial proportions,

a pursuit of beauty through comprehensive analysis,

the attending orthodontic doctor for celebrities, including famous idols,

the expertise and rich know-how to prevent unwanted facial shape changes,

From Director Jeon Jae-min of Gangnam Saero Dental Clinic,

a new smile

a new beginning

I hope you achieve beauty through small changes in facial shape.
