- Hours and registrations can change. Confirm the current schedule, treating dentist, and treatment plan directly before booking.
For people who cannot leave work during the day, the first practical question is often not which clinic has the strongest advertising claim, but whether repeat appointments are possible after work. Many clinics in Seosan mention evening care, yet their actual closing times vary by day and are not always easy to compare.
We therefore checked the day-by-day hours published on Kakao Map first. Only clinics with at least one weekday closing time of 7 PM or later remained. Their HIRA specialist and cone-beam CT registrations, Naver visitor-review volume, and Google review sample were then compared. Implant care normally involves consultation, surgery, restoration, and follow-up, so a usable schedule matters across several visits rather than on the first appointment alone.
All 5 qualifying clinics in Seosan
Exactly 5 clinics met the mandatory filter, so this is the complete qualifying set found in the current review scope rather than a shortened top list.
The order uses one reproducible public-evidence score: registered specialists up to 5 points, simultaneous oral-surgery and prosthodontics registration, cone-beam CT registration, and visitor-review sample. “Open at 7 PM or later” is an entry requirement and does not add points.

How the order is calculated
One published formula determines the order. No clinic can pay to move upward, and editors do not rearrange the list by preference. The clinic cards display the same inputs used in the calculation.
- Mandatory filter
- A clinic must list at least one weekday closing time of 7 PM or later on Kakao Map. Clinics that do not meet this requirement are excluded regardless of score. The filter is applied before any score is calculated.
- Scoring formula
- Registered specialists: 1 point each, capped at 5; both oral surgery and prosthodontics registered: 3 points; cone-beam CT registered: 1 point; visitor-review sample: logarithmic value capped at 3. Blog-post volume is excluded because it can reflect marketing activity. The specialist cap prevents a university dental hospital with many specialists from dominating every other public indicator.
- Tie-breaks
- Naver visitor-review count, then Google review count, then clinic name.
- Conflicting hours
- Clinics with conflicting Kakao and Google hours are removed from time-based lists.
Anyone applying the displayed specialist, cone-beam CT, and review figures to the formula should reproduce the same order. Hours came from Kakao Map and were checked on 2026-08-01. Naver visitor-review excerpts remain in their original Korean so that wording is not altered by translation.
Which check should come first for you?
Start with clinics that list evening hours on several weekdays, then confirm the last check-in time for the exact day you plan to visit.
Compare the Sunday and Saturday-afternoon lists for the same area before deciding which schedule is sustainable.
Check whether oral and maxillofacial surgery and prosthodontics specialists are both registered, then ask who handles each stage.
Questions to confirm before consultation
Frequently asked questions
QHow were evening hours verified?
⌄
We collected the weekday hours published on Kakao Map on the stated data date and included only clinics with at least one closing time of 7 PM or later. A clinic was excluded when its Kakao and Google hours conflicted.
QWhich clinic on this list has the most registered specialists?
⌄
더센트럴치과의원 has the largest HIRA-registered specialist count on this list, with 1. The count is a public indicator of registered fields, not a guarantee of treatment outcome.
QWhich clinic has the largest visitor-review sample?
⌄
더센트럴치과의원 has 1,000 Naver visitor reviews, the largest sample among the clinics shown here. Review volume indicates sample size, not clinical quality.
QIs this a ranking of the best clinical outcomes?
⌄
No. The order reflects only publicly checkable evidence: registered specialists, registered equipment, and review-sample size. The formula and clinic-level inputs are displayed so the order can be reproduced.
QDoes a clinic missing from this page fail the “Open at 7 PM or later” condition?
⌄
Not necessarily. It may be outside the current review scope or the required information may not be publicly available. Confirm current registration and hours directly with the clinic before booking.
