Compare
Every sub-score, printed as is
The ranking is the plain sum of the numbers in this table — you can check it without a calculator. Specialists and cone-beam CT units follow HIRA registration; visitor review counts come from Naver Place.
Google ratings are collected from Google Maps and shown for reference only — they never enter the score. Clinics with no rating collected are left blank.

FAQ
Frequently asked
How was this ranking of orthodontic clinics in Seongdong-gu, Seoul decided?＋
We add up published facts on a 20-point scale: years open, how many visitor reviews have accumulated on Naver and online information on the clinic's website for every treatment, plus treatment-specific HIRA records such as registered specialists and cone-beam CT units. Every sub-score is printed in the comparison table so anyone can recalculate it, and no clinic can pay to move up.
Does this ranking measure clinical skill?＋
No. It ranks how much public evidence can be verified, not treatment outcomes. The right clinic depends on your own condition, so confirm the details in person at a consultation.
Which clinic in Seongdong-gu, Seoul has registered the most cone-beam CT units?＋
장미치과의원 has 1, the most among the 10 clinics listed. A cone-beam CT scans bone thickness and nerve canal position in three dimensions; unit counts are as registered with HIRA.
Which clinic has the most registered specialists by field?＋
박플란트치과의원, with 2 in total. The breakdown is Advanced General Dentistry (2).
Which clinic has the most Naver visitor reviews?＋
연세고마운 치과의원, with 885. These are reviews left by people whose visit was recorded. The count reflects how much visit experience has accumulated, not how good the treatment is.
Are any of these 10 clinics a dental hospital rather than a clinic?＋
All 10 candidates in Seongdong-gu, Seoul are dental clinics. A clinic can make it easier to stay with one dentist through the whole course of treatment, but check what procedures it handles before your first visit.
Which clinic in Seongdong-gu, Seoul has been open the longest?＋
이병준치과의원, established in 1989. Opening dates follow HIRA registration.
Which clinics have a registered orthodontist?＋
4 of them — 장미치과의원 (1), 국윤아한마음부부치과의원 (1), 강치과의원 (1), 서울유치과교정과치과의원 (1). For orthodontics, whether an orthodontic specialist is registered is the key published signal: each one scores 2 points, up to 4.
What should I ask at an orthodontic consultation?＋
Ask for the expected duration and cost per appliance type, whether monthly adjustment fees are included, the price of retainers, and the refund rule if you transfer mid-treatment — in writing. Also see whether the plan is explained from diagnostic records such as a cone-beam CT and a lateral cephalometric X-ray.
Why is 장미치과의원 listed first?＋
It scores 15 points, the highest here. That comes from 1 registered specialists, 1 cone-beam CT units and 487 Naver visitor reviews. The sub-scores are shown in the comparison table.
Where does the information on this page come from?＋
Specialists, cone-beam CT units, opening dates and facility category come from Health Insurance Review and Assessment Service (HIRA) open data; visitor and blog review counts come from Naver Place. We have no partnership with any clinic, and the collection period is printed at the bottom of the page.
How this page was built, and what it cannot tell you
Specialist mix, cone-beam CT units, opening dates and facility category come from Health Insurance Review and Assessment Service (HIRA) open data; visitor and blog review counts come from Naver Place. Data was collected between 2026-09-24 and 2026-09-26, and a clinic that changes its filing can differ from what is shown here.
Implant brands, the extra cost of a bone graft, which dentist actually performs the surgery, and warranty terms are not in any public record. Those belong in a consultation, in writing. This ranking orders how much published evidence can be verified — not how good the treatment is.
