Hello
This is Apgujeong Invisalign Dental Clinic.
During orthodontic consultations, we often hear questions like, “Other dental clinics say Invisalign extraction treatment can’t be done, so why do you say it can?”
This post is for those who are curious about that.
Invisalign extraction orthodontics is possible, and it works well.
Of course, not every extraction case works well with Invisalign.
If you consider factors such as tooth length, the condition of the gum bone, the angle at which the molars have tipped over, the angle of the front teeth, and skeletal analysis, you can determine whether extraction orthodontics with Invisalign will go well or whether it will not work well and you will eventually need fixed appliances.
In other words, cases in which Invisalign extraction orthodontics works well and cases in which it does not are clearly distinguished during the initial detailed diagnosis.
We do not recommend Invisalign to every patient who needs extractions.
There are also many cases where we say, “Please do Clippy-C instead of Invisalign.”
However, if a patient says during the initial consultation, “Invisalign extraction orthodontics will work well for me,” then it does work well.
Of course, the appliance has to be worn properly.
2022.12
This patient visited in December 2022 with protrusive mouth as the chief complaint.
The midline of the front teeth was off, and the front teeth were tilted.
2022.12
The front teeth were quite protruded. The protrusion and protrusive mouth were severe, making it difficult to close the lips, and skeletal analysis also showed a skeletal Class II malocclusion (recessed chin).
2022.12
Severe protrusive mouth with prominent front teeth clearly requires extraction orthodontics.
The patient chose Invisalign treatment, and treatment began.
Nine months after starting treatment, about one-third of the extraction space had closed.
This was a patient with excellent appliance compliance.
During treatment, as the front teeth showed deeper overbite, we placed an orthodontic mini screw in the front teeth area and used elastics to try to control the vertical position of the front teeth.
Even if it was not part of the original treatment plan, additional appliances or elastics may be needed after monitoring during treatment.
By March 2024, after wearing all 70 aligners at one-week intervals over 1 year and 3 months, this is the result.
24.03
The midline improved a lot, but a slight mismatch remains.
24.03
Even though only the first set was completed, the bite is fairly good.
There is a gap between the front teeth.
24.03
About 1 mm of extraction space remains.
To improve these areas further, we moved on to remaking the aligners.
From June 2024 to November 2024, after wearing all 20 additional aligners, this is the result.
24.11
The gap between the front teeth is gone, and the midline is exact.
24.11
The bite is also perfect.
If we only look at the intraoral photos, treatment could be finished here. But
24.11
When viewed as a whole face, the tilt of the front teeth is noticeable.
You cannot tell this from intraoral photos alone. This is something that needs to be checked by taking facial photos from time to time.
The patient did not particularly notice it, but for a better result, we proceeded with a second remake.
Even if the patient may not realize it, I am doing my best to achieve a perfect result.
From December 2024 to April 2025, after wearing all 16 aligners of the second additional set, this is the result.
25.05
If the bite is not good, we do not finish treatment.
Now, let’s look at the before-and-after comparison.
The total treatment period was 2 years and 6 months, and there were two remakes in total.
2022.12~2025.05
The extraction spaces were neatly closed.
2022.12~2025.05
Improvement in the midline and canting
2022.12~2025.05
Improvement in front-tooth protrusion and proper front-tooth angle
2022.12~2025.05
With the second remake, the occlusal plane regained a level position.
2022.12~2025.05
Proper front-tooth angle, neither protruded nor excessively upright
2022.12~2025.05
2022.12~2025.05
At last, the lips close comfortably.
Because the front teeth were moved backward by a large amount, slight root resorption is visible in the front teeth.
Root parallelism is good.
Molars tipping over is the biggest challenge in Invisalign extraction orthodontics.
Only when this part is well controlled can we say the result is good even on X-rays.
I hope this was helpful for those wondering whether protrusive mouth extraction orthodontics can be treated with Invisalign.
