Don’t give up on adult prognathism just because it’s late

Examples of non-surgical correction possible without surgery

Non-surgical adult prognathism

Prognathism refers to a condition in which the lower jaw extends

forward compared to the upper jaw.

If it is a child in the growth period, it may be controlled without surgery through early treatment,

but after someone has already become an adult,

surgery is often the clearest option.

That said, surgery is not the only answer in every case.

Under certain conditions, adults can also be treated for prognathism

with orthodontics alone.

Types of adult prognathism

Adult prognathism also has different treatment directions depending on the cause.

Maxillary undergrowth crossbite:

This occurs when the upper jaw has not developed enough. An upper jaw expansion device is used to widen the upper jaw and restore balance.

Mandibular overgrowth crossbite:

This is when the lower jaw has grown excessively. Because it is a bone issue, surgery is recommended in principle, but in some cases improvement is possible with orthodontic treatment using mini-screws.

Upper and lower dental arch imbalance:

If it is a tooth alignment problem rather than a skeletal issue, it can be sufficiently improved with orthodontics alone.

Adult prognathism correction method

If non-surgical prognathism treatment is possible,

orthodontic appliances are used

to induce improvement by rotating the lower jaw clockwise.

This does not actually shorten the jawbone itself,

but rather adjusts the position to achieve harmony.

Therefore, if the jawbone itself is excessively long,

surgery is necessary,

but if that is not the case,

orthodontics alone can improve both function and aesthetics.

Adult prognathism treatment process

The treatment plan varies depending on the individual’s condition.

Most crossbites involve the lower jaw protruding forward,

so creating space for backward movement is the first priority.

If the teeth are large or the lack of space is severe,

extraction orthodontics is needed,

and if the lack of space is not significant,

interproximal reduction is used to create about 0.25 mm of space,

while in cases where the maxilla is narrow,

an expansion device is used to secure space.

Through a plan tailored to the situation,

the position of the lower jaw is corrected.

Reviews before and after adult prognathism correction

Reviews before and after adult prognathism correction can change the idea that non-surgical prognathism treatment is too late!

Even as an adult, if you receive the proper diagnosis and treatment,

you can expect noticeable changes by adjusting the position of the lower jaw.

However, this does not apply to every case,

so consultation with a specialist is essential.

Choosing a clinic for adult prognathism

Adult prognathism treatment is highly difficult,

and case-by-case judgment is important.

Therefore, choosing medical staff with experience and expertise

is key.

Gangnam Saero Dental Clinic

offers direct treatment from medical staff recognized for their expertise,

including experience as the attending orthodontist for celebrities,

a publication on non-extraction orthodontics, the only one of its kind in Korea,

a paper published in the American Journal of Orthodontics,

and advisory work for Trinity.

There is no need to give up on prognathism correction just because you are an adult!

Early treatment is ideal,

but there are certainly cases where improvement is possible without surgery even if it is late.

Both adult prognathism and non-surgical prognathism

can lead to a new smile and a new beginning

at Gangnam Saero Dental Clinic.
