hello. Director Kim Hyeon-sun of Ceramic Dental Clinic no see.

 

When you say prognathism, many people think
“Doesn’t this absolutely require surgery?”
People often worry about that.

 

but Not everyone with a prognathism needs surgery.
Because the jawbone and teeth are connected and harmonious,
Depending on the cause, there are many cases where sufficient improvement can be achieved with orthodontic treatment alone.

today Why does a prognathism occur? , and In what cases can non-surgical correction be improved? I will guide you step by step.

 

 

 

1. What is a prognathism?

 

“A prognathism is when the lower jaw protrudes further than the upper jaw.
'Overbite (Class III)', where the lower teeth protrude forward of the upper teeth It tells the status.

 

 

 

In this case,

 

• frontal In the jawline, the jawline looks sharp.
• side In , the lower jaw appears to be unusually protruding.

Also, because the upper jaw is often narrow and the lower jaw is wide,
Simply “pushing the chin back” is not an appropriate treatment.

 

The structure of the teeth and jawbone A precisely analyzed correction plan This is very important.

 

 

 

2. Why does a prognathism occur?

 

Cause Type	explanation
Congenital factors (genetics)	Approximately 70-80% of patients with prognathism have a family history of the condition. The developmental pattern of the jawbone is genetically determined.
acquired factors (habits)	Things like jaw clenching, mouth breathing, chewing on one side, and sleeping positions can affect jaw growth.

 

in other words, Jaw structure at birth + growth environment + lifestyle habits All of these affect the chin.

 

 

 

 

3. Cases where correction is possible without surgery

 

Even if it's a spatula chin If the imbalance of the jawbone itself is not severe, ,
Improvement is possible with orthodontic treatment alone.

 

✔️Teaching If it can be improved with sincerity

• Crossbite Teeth alignment problems If it comes from

• of the chin If the difference before and after is minor

• During the growth period (adolescence) Period when growth control is possible

 

✔️Examples of treatment methods

• Miniscrew (fixed) It is used to move the lower teeth backward and guide the upper and lower teeth into a normal occlusion.

 

 

The key is Teeth arrangement + jaw position + facial proportions Considering them together.
It is different from orthodontic treatment that simply straightens teeth.

 

 

 

4. So in what cases is surgery necessary?

 

In the following cases: Surgery + orthodontic treatment This may be necessary.

 

• The lower jaw Protruding significantly forward If it is done

• facial asymmetry If accompanied by this

• When there is a large difference in the growth of the upper, lower, left, and right jawbones

 

in other words, Whether or not surgery is necessary depends on the structural differences in the jawbone. is decided by.

 

 

 

 

5. A prognathism can lead to functional problems.

 

A prognathism is not simply a cosmetic issue.

 

✔️Possible issues

• Difficulty chewing food (decreased masticatory function)

• Inaccurate pronunciation (especially pronunciation of ㅅ and ㅆ)

• Temporomandibular joint discomfort/headache

• Unconscious deterioration of oral habits

 

thus It is recommended to begin diagnosis and treatment as soon as possible.

 

 

 

 

6. Conclusion

 

The prognathism is Surgery, no matter what! Not this,
It is important to choose a treatment that is appropriate for the cause, severity, and age.

 

There are many cases where correction alone can be sufficient to resolve the issue.
