Hello,
This is Apgujeong Yonsei Baro Dental Clinic, an orthodontic clinic in Gangnam.
The combination of double-jaw surgery and Invisalign treatment is effective and advantageous in terms of treatment time.
This post shows the Invisalign treatment process after surgery-first treatment for a patient who required double-jaw surgery due not only to facial asymmetry but also to a protruding lower jaw.

23.01
This patient visited us for surgery-first orthodontic treatment with double-jaw surgery and Invisalign.
There was facial asymmetry, as shown by the misaligned dental midline.

23.01
Because the front teeth as well as the molars were in a reverse bite, the patient was diagnosed with a skeletal Class III malocclusion.
The patient visited us hoping to receive postoperative orthodontic treatment with Invisalign after deciding to undergo surgery-first treatment at a hospital performing double-jaw surgery.
Determining whether surgery-first treatment is possible requires the judgment of both the surgeon performing the double-jaw surgery and the orthodontist.
This photograph was taken one month after the patient underwent double-jaw surgery as the first procedure.

23.02
Severe open bite can be observed.
This was not because the surgery had gone wrong; it was because the patient was still undergoing physical therapy.
It is necessary to stabilize the jaw position by attaching rubber bands to screws placed in the gums.
Depending on the surgical method, such as IVRO or SSRO, and the surgical outcome, this process may take several months.
We decided to begin orthodontic treatment after the jaw position had stabilized and continued physical therapy for several more months.

23.05
After approximately three months of physical therapy, the open bite had significantly decreased when the patient returned.
The remaining open bite now needed to be addressed through orthodontic treatment.

23.05
At this stage, we performed an Invisalign scan and began the process of manufacturing the aligners.
After waiting one and a half months for the aligners to be manufactured and delivered, the patient began wearing the first aligner in June 2023.
A total of 23 aligners were manufactured for the first set. This photograph was taken after the patient had worn all the aligners over five months.

23.10
The dental midlines were aligned, and the open bite had been resolved.

23.10
However, there were areas that could be improved in terms of the bite and alignment, so we proceeded with a refinement.

23.11
A month is also needed to manufacture the aligners for a refinement.
After waiting one month, the patient received and began wearing the second set of aligners.

23.11
The second set included rubber bands to establish the proper molar bite relationship.

23.07
The treatment is finally complete.

This photograph shows the fixed wire retainer in place.

23.01~24.07
The combination of Invisalign clear aligners and double-jaw surgery consistently produces good results.
Orthodontic treatment usually takes around one year. For this patient, it took a total of one year and one month, from wearing the first aligner in June 2023 through July 2024. Excluding the one-month wait for the aligners during the refinement process, the actual treatment period was one year.
Frequently Asked Questions About Double-Jaw Surgery and Invisalign
Is Invisalign treatment possible after double-jaw surgery?
Yes, it is possible. However, it does not apply to every patient, and the surgical and orthodontic plans must be established together.
What is surgery-first treatment?
It is a treatment approach in which double-jaw surgery is performed first, followed by orthodontic treatment after recovery and physical therapy.
Why does an open bite occur immediately after surgery?
It may temporarily appear while the jaw position is stabilizing, and it can be improved through physical therapy and subsequent orthodontic treatment.
Is refinement necessary after double-jaw surgery?
Yes. Additional aligners may be manufactured to adjust the bite and tooth alignment more precisely.
If you are concerned about needing double-jaw surgery but feel that traditional braces with wires would be burdensome, we hope this post was helpful.
