Angel Aligner Clear Aligners in Seoul
Quick answer
Angel Aligner is a clear, removable aligner system offered at Isu Yonsei Baro Orthodontics as an alternative to Invisalign. It works on the same principle: a sequence of custom trays that move teeth gradually. Dr. Sally Lee, an orthodontic specialist, designs and checks the plan herself and helps you decide which aligner brand fits your case after examination.
What Angel Aligner is
Angel Aligner is a clear aligner system that, like other aligner brands, uses a series of thin custom trays to move teeth in small, planned steps. Attachments bonded to some teeth help the trays grip, and elastics are sometimes added to adjust the bite.
From the patient's side, daily life looks very similar to other aligners: you remove the trays to eat and brush, then put them back. Results depend far more on the treatment plan and on how consistently you wear the trays than on the brand name.
Angel Aligner or Invisalign?
Isu Yonsei Baro offers both systems. Rather than pushing one, Dr. Lee looks at your case and your priorities and explains the trade-offs. Factors she typically discusses include:
- The type and amount of tooth movement you need
- Material and fit preferences, and how the trays feel to you
- Your timeline, travel plans and how many refinements may be needed
- Cost, which is quoted in writing after the exam for either option
For some patients the systems are interchangeable; for others one has a practical advantage. The point is that the choice is made with a specialist after records, not from an advertisement.
Who it may suit
- Adults with crowding, spacing or relapse after earlier treatment
- Teens who can commit to full-time wear
- Professionals who prefer an appliance that is hard to notice in meetings
- Patients comparing aligner options and wanting a second brand to consider
What to expect at Isu Yonsei Baro
At the first visit, which takes about 60 minutes, we capture your teeth with an intraoral digital scanner (no impression putty), take X-rays or a RAY Quantum 5D CT, and record a 3D face scan. Dr. Lee examines your bite and jaw, then talks you through suitable options, an estimated timeline and a written estimate in English.
If you choose Angel Aligner, Dr. Lee adjusts the digital setup tooth by tooth before approving manufacture. In Dr. Lee's practice, the same planning standard is applied whichever aligner brand is used: roots are checked on the CT, and the final position is judged against your lips and facial profile, not just against the teeth on screen.
Check-ins are usually spaced several weeks apart. Evening hours on Mondays and Thursdays and Saturday mornings help working patients keep appointments, and the clinic is a one-minute walk from Isu Station Exit 2.
Living with aligners
- Wear trays almost all day; time out of the mouth slows progress
- Brush before putting trays back to protect enamel
- Drink only water while wearing them
- Keep your previous set as a backup when traveling
- Store trays in their case, never in a napkin, to avoid losing them
If you will be traveling for longer than your usual check-in interval, let us know in advance so the aligner sequence and any spare sets can be planned around the trip.
Individual results and side effects vary; treatment is decided after examination.

Frequently asked questions
Is Angel Aligner as effective as Invisalign?
Both systems move teeth with custom clear trays, and outcomes depend mainly on the orthodontist's plan and your daily wear. Some cases may suit one system better for practical reasons. Dr. Lee explains which she would recommend for your specific case after examining you and reviewing your scans, rather than making a general claim.
Can I switch from Invisalign to Angel Aligner?
In some situations a case can be re-planned on a different system, for example during re-treatment or refinement, but this needs fresh scans and a new plan. Dr. Lee would assess where your teeth are now and explain whether a switch makes clinical sense and what it would involve.
How often do I need to visit with Angel Aligner?
Many patients are seen every several weeks so Dr. Lee can check fit, tracking and attachments. The schedule is adjusted to your case and travel plans. Evening and Saturday hours are available, and the clinic is a one-minute walk from Isu Station Exit 2.
Do I get English documents for insurance?
Yes. Isu Yonsei Baro provides English receipts, itemized statements, medical certificates and doctor's letters that you can submit to overseas insurers. Coverage depends entirely on your own policy, so it is worth checking your plan's orthodontic benefits before treatment starts.
