Treatments
What we treat
We diagnose whether a bite problem comes from the teeth, the jaw bones, or the jaw joint — and design non-surgical treatment whenever surgery is not strictly necessary.
01
Non-surgical skeletal orthodontics
Underbite (protruding lower jaw), facial asymmetry, lip protrusion, receding chin, gummy smile, deep bite and open bite — assessed with cephalometric analysis to determine whether correction is possible without jaw surgery.

Clear aligners for international patients
Digitally planned aligner treatment with visit schedules built around your trips to Korea. Stages of aligners can be prepared in advance, so monthly visits are not required.
Learn more →03
Growth-stage orthodontics for children
Facemask therapy for childhood underbite, headgear, and habit-control appliances — treatments that guide jaw growth and are only possible during the growth period.

How we practice
1
One doctor, start to finish
Dr. Keun-Hye Lee — a board-certified orthodontic specialist — personally handles diagnosis, every adjustment, and finishing treatment.
2
Non-surgical first
For underbite and facial asymmetry we distinguish skeletal causes from jaw-joint and bite causes. When the cause is functional, correction can often be attempted without surgery.
3
Experience with patients abroad
The clinic was previously registered with the Ministry of Health & Welfare for treating international patients and plans aligner treatment around overseas schedules.
