Adult prognathism treatment

Even if it is late, it can still be treated without surgery

Adult non-surgical prognathism

What is commonly called prognathism is

a condition where the lower jaw protrudes slightly more than the upper jaw,

and it is best treated early during childhood growth,

but if you have already become an adult

and are considering treatment,

surgery is in fact the clearest method,

but in certain cases, orthodontic treatment alone is enough

for non-surgical prognathism.

As mentioned when explaining non-surgical prognathism correction methods for children,

prognathism treatment varies depending on the cause and type.

The same applies to

adult non-surgical prognathism correction methods.

Maxillary undergrowth with anterior crossbite

An anterior crossbite caused by undergrowth of the upper jaw,

using an arch expansion device

to widen the left and right sides of the alveolar bone and balance it with the lower jaw

Mandibular overgrowth with anterior crossbite

An anterior crossbite caused by overgrowth of the lower jaw,

surgery is recommended because it has a skeletal cause

Possible non-surgical cases use mini screws

Upper and lower bite imbalance

An anterior crossbite in which the lower dental arch

protrudes forward more than the upper dental arch,

and because the cause is dental,

non-surgical treatment is possible

Under the dentist’s judgment,

if it is diagnosed as a non-surgical prognathism case that can be sufficiently corrected with orthodontic treatment,

orthodontic appliances can be used

to improve prognathism by inducing clockwise rotation of the lower jaw.

In this case, the actual length of the jawbone does not become shorter;

rather, changes in the position of the jawbone are induced.

Therefore, when the jawbone is long and the anterior crossbite is skeletal in nature,

surgery is needed

to clearly restore function and esthetics,

while anterior crossbites that are not of that type can

restore proper function and esthetics

through orthodontic treatment.

If non-surgical prognathism is possible,

an individualized treatment plan will be established according to each person’s condition.

Because anterior crossbite is mostly a form in which

the lower jaw protrudes forward,

to move the lower jaw backward,

extraction is performed to secure space for tooth movement.

If the teeth are large

and the lack of space is not severe,

tooth separation within 0.25 mm of enamel is performed

for non-extraction orthodontics,

and if the transverse width of the maxilla is narrow,

space for movement is secured through a maxillary expansion device.

Even if it is late, if you visit for a diagnosis now

and proceed with non-surgical prognathism orthodontic treatment,

adults can also have the lower jaw guided to the correct position,

allowing you to see before-and-after results for adult prognathism.

(Eligibility varies by individual, so consultation with a medical professional is essential.)

A choice for the years ahead,

if you want to receive non-surgical prognathism orthodontic treatment,

it is most important to get a consultation from medical professionals with strong expertise.
