Hello.
It is not possible to correct skeletal prognathism and asymmetry with orthodontics alone.
Double-jaw surgery is needed.
However, orthodontics alone can make anterior crossbite and a deviated midline into a normal bite.
Treatment that normalizes the bite while leaving the bone problem unchanged, without double-jaw surgery, is called compensatory treatment.
23.12~25.03
Today, I will show you how prognathism and asymmetry were treated with Invisalign without double-jaw surgery.
The total treatment period was 1 year and 3 months. There was 1 remaking.
23.12
This is a patient in their 40s who visited in December 2023 for prognathism treatment.
In addition to skeletal prognathism, there is also asymmetry with the lower jaw shifted to the left.
23.12
The front teeth are completely in reverse occlusion.

The teeth are relatively well aligned, but after living for a long time with an anterior crossbite, the upper front teeth show severe wear from hitting the lower front teeth.
Non-extraction treatment with Invisalign was recommended. The plan was to push the entire lower arch backward into the wisdom tooth space to resolve the anterior crossbite and midline discrepancy.

The treatment is being carried out with two mini-screws, which are orthodontic anchors, placed in the lower jaw, and Class III elastics are being used.
This is what it looked like after wearing all the appliances from the first set at 10 months into treatment.
24.10
The major work is done, but some unfinished parts remain.
The anterior crossbite has been resolved, but the midline is still slightly off.
24.10
There is still an area where the molar bite is open, so remaking began in October 2024.
After wearing all the additional appliances for 4 months until March 2025, the treatment was completed.
25.03
The midline is well aligned.
25.03
The molar bite is good.
25.03
This is what it looks like with the retainers attached.
At first, the expected treatment period was explained as 1 year and 6 months, but the treatment was successfully completed in 1 year and 3 months.
Let's look at the before-and-after comparison.

On the post-treatment panoramic X-ray, there is no root resorption, and the root alignment is good.
The reason this seemingly difficult non-surgical prognathism and asymmetry treatment, even though it was done with Invisalign, finished quickly and well is bite force.
When the biting force is strong, Invisalign treatment often finishes quickly and well. If your usual biting force is strong, the clear aligners stay firmly attached to the teeth, which helps transmit force effectively.
That is why close fit of the Invisalign appliance is so important.
