Hello,
This is Apgujeong Yonsei Baro Dental Clinic, specializing in Invisalign in Gangnam and Apgujeong.
Today’s topic is Invisalign extraction treatment for protruding lips.
Do you remember the patient with a gummy smile whom we introduced a while ago?
This is the patient featured in that post, and we would like to introduce the final treatment results as well.
▼▼▼▼▼▼
During Invisalign consultations, patients often ask us about what they were told at other dental clinics.
One of the questions we hear frequently is:
> I was told that Invisalign cannot move the roots.
If the roots cannot be moved, extraction orthodontic treatment cannot be completed properly.
The key to extraction treatment is moving the roots in parallel into the extraction spaces.
Q. Can Invisalign not move the roots?
The answer is no.
Invisalign can also move the roots.
However, this does not happen automatically in every case. The following are required together:
In extraction treatment especially, treatment can only be completed successfully when not just the crowns of the teeth but also the roots are moved in parallel.

The patient wanted to correct two issues:
Protruding lips and a gummy smile, in which a significant amount of gum showed when smiling.
The deep overbite was severe enough that the lower front teeth were not visible because they were covered by the upper teeth.
There are various types of protruding lips. When the gum area appears prominent without the front teeth being flared forward, this is referred to as gum protrusion.
The two upper premolars were extracted, and Invisalign orthodontic treatment began.
22.09
This photo was taken one week after the premolars were extracted, on the day the patient began wearing the first Invisalign aligner.
Many patients worry that the extraction spaces will be very noticeable after premolar extraction.
They are not visible during ordinary speech, and depending on the shape and size of the mouth when smiling broadly, they may or may not be visible.
This patient had good compliance and wore the aligners diligently. However, in May 2023, nine months after starting the first set of aligners, there was a period when the patient was unable to wear them properly due to personal circumstances.
At that point, the molars could be seen tipping into the extraction spaces, so all of the remaining aligners were discarded and the first remake was produced.
After the additional aligners were made, the patient began wearing the second set in July 2023, following the one-month production period.
From this point, miniscrews were placed near the front teeth to actively address the gummy smile, and elastics were attached as well.

At the time of the remake, approximately half of the extraction spaces remained.
This is the result after wearing all of the first set of additional aligners for one year, through July 2024.
24.07
The deep overbite had been corrected, and most of the extraction spaces had disappeared, but the midline was still slightly off.
24.07
A small gap remained in the extraction space.
24.07
There was also an area where the molar occlusion was not fully contacting, so the aligners were remade once more.
After wearing all of the second set of additional aligners from August through December 2024, treatment was completed in December 2024.
24.12
The midline is well aligned.
To correct the gummy smile, the upper front teeth were intruded, which caused the gums to cover more of the teeth and made their visible height appear shorter.
Now that orthodontic treatment is complete, the gum line will be refined with gum contouring.

Treatment is not completed if the occlusion is not satisfactory.

This is the result with the retainers in place.

Let’s look at the before-and-after facial photos.
22.09~24.12
2022.09~2024.12
The improvement in the gummy smile is noticeable.
2022.09~2024.12
The result shows a moderate lip profile with the protrusion reduced, without an overcorrected appearance.

24.12
It can be confirmed that the teeth moved in parallel all the way to the roots, without the molars tipping into the extraction spaces.
Can Invisalign move the roots?
Yes, it can.
Extraction orthodontic treatment is a long-term process that takes about two years.
With treatments such as Invisalign in particular, problems can arise during periods when the aligners are not worn properly, making remakes necessary.
Even so, if the orthodontist responds appropriately to these variables and the patient resumes wearing the aligners diligently, very good results can be achieved.
Extraction Invisalign Treatment: Frequently Asked Questions (FAQ)
Can Invisalign be used for extraction orthodontic treatment?
Yes. Numerous extraction treatment cases are currently being treated with Invisalign worldwide.
Can Invisalign not move the roots?
No. Root movement is possible when an appropriate treatment plan is established.
Are the spaces very noticeable after extraction?
They are barely visible during ordinary activities and may only be partially visible when smiling broadly.
What happens if I do not wear the aligners properly during treatment?
Tooth movement may differ from the treatment plan, and additional aligners may need to be made.
Can protruding lips and a gummy smile be improved at the same time?
This is possible depending on the diagnosis. Auxiliary appliances such as miniscrews may also be used when necessary.
Invisalign Extraction Treatment at Apgujeong Yonsei Baro Dental Clinic
Extraction orthodontic treatment is not simply a treatment to straighten the teeth.
The positions of the tooth roots,
the lip profile,
gum exposure,
and the occlusion
must all be considered together.
In Invisalign extraction treatment especially, experience in responding to unexpected variables during the treatment process is important.
Although this case also required a remake during treatment, appropriate management and the patient’s cooperation allowed us to complete it with good results.
If you are concerned about protruding lips and a gummy smile, consider receiving an accurate diagnosis to determine the treatment method suited to you.
