전신마취 및 깊은 진정

치과가 전신마취 또는 깊은 진정 하의 치료를 문서화하는지 여부 — 환자가 잠들어 아무것도 인지하지 못하는(시술을 느끼지도, 보지도, 듣지도 못하는) «수면 치과 치료». 환자가 깨어 있고 반응하는 일반적인 의식하 진정은 여기에 포함되지 않습니다. 참고용 정보이며 투명성 점수에는 영향을 주지 않습니다.

  • ✓ 전신마취 / 깊은 진정 (수면 치과 치료) — 전신마취 / 깊은 진정 문서화됨 Filled 2026-09-06 from the clinic's own channel, which is what rule (A) requires here: 'sleep dentistry' is one of the site's five service headings, with pages for sedation implants and dental phobia, the home page states (in translation) 'we operate a sleep-anaesthesia system', and the About page states the practice has extended into 'dental treatment for people with disabilities and dental treatment under general anaesthesia'. The Bookimed profile's separate claim that the clinic is KOIHA-accredited is not repeated anywhere on the clinic's own site and was not used. [w1] [w2]

요약

둔산 지구에 위치한 치과의원으로 2007년부터 운영되어 왔으며, 두 곳의 지점을 둔 DIER 그룹의 대전 지점입니다. 다른 지점은 대구 중심가에 있습니다. 외국인 환자에게는 임플란트, 교정, 심미 치과 센터로 소개됩니다.

The site is a single JavaScript-rendered application shared by both DIER branches (dierdg.com/daejeon and dierdg.com/daegu); none of its content was readable without a browser, so treatment lists, dentist names and prices are recorded as unchecked and queued for a manual browser check rather than guessed. The Daegu branch (25 Dongseong-ro, Jung-gu, Daegu, 053-428-5885) is a separate HIRA institution and is not this card.

✓ 작동하는 웹사이트 보유 Updated 2026-09-06. The domain HIRA records, dier.co.kr/daejeon, and the dierdg.com/daejeon it resolved to now both redirect to dier.kr, which is the clinic's current site: its footer publishes Diereu Chigwa-uiwon, business registration 314-27-96299, registered representative Lee Jeong-seong and the card's exact address, 6F Daeil Building, 20 Dunsan-ro, Seo-gu, Daejeon. [w1] [reg1] 4/4
✓ 치과의사 이름 명시 Filled 2026-09-06 from the clinic's own medical-team tab, which the research pass could not render. Four dentists are named with full credentials: head director Lee Jeong-seong, director Lee Wan-jae, director Lee Geon-yeong and director Gu Hyeon-jeong. [w2] 3/3
✓ 치과의사 전문 분야 명시 Filled 2026-09-06. Two of the four carry a named Ministry of Health and Welfare board specialty - Lee Geon-yeong, Ministry of Health and Welfare board-certified oral and maxillofacial surgeon, and Gu Hyeon-jeong, Ministry of Health and Welfare board-certified orthodontist - and the other two publish their fields (Lee Jeong-seong: accredited by the Korean society of temporomandibular joint and occlusion, lingual orthodontics and implant courses, member of the Korean academies of esthetic dentistry and prosthodontics; Lee Wan-jae: implant and endodontic fellowships, member of the Korean Academy of Geriatric Dentistry). [w2] 2/2
? 실제 치과 사진 Still unresolved. The site is built on the QUV platform and delivers its imagery through CSS background rules rather than <img> elements, so no image can be identified by filename or dimensions from the rendered page; nothing was concluded either way. 0/2
✓ 서비스 목록 게시 Filled 2026-09-06. The rendered site publishes a structured service list across five headings - implants, laminates, front-tooth contouring, orthodontics, 'sleep dentistry' (the site's own term for sedation) - each expanding to its own set of pages (full-arch, digital, front-tooth and revision implants; no-prep and front-tooth laminates; diastema, peg lateral and chipped-tooth treatment; clear and lingual aligners; sedation implants, dental phobia and disability dental care). [w1] 3/3
✓ 명확한 연락처 정보 Phone 042-487-7599 and the Dunsan-ro address are published in the HIRA institution register; the clinic-side listing could not be read. [reg1] 2/2
✗ 영어 웹사이트 버전 Filled 2026-09-06. The site was read in a browser across the home page, the About / Medical team / Opening hours tabs, the fee page and several service pages: navigation and content are Korean throughout, there is no language switcher, and no anchor points at an /en path. [w1] [w2] [w3] 0/2
✓ 주소 및 지도 게시 Street address and WGS84 coordinates published in the HIRA national institution register. [reg1] 2/2

가격 투명성

9 / 15

환자가 방문 전에 비용을 가늠할 수 있는지 여부. 게시된 가격 범위도 인정되며, 정확한 가격은 필수가 아닙니다.

✓ 가격 또는 가격 범위 게시 Filled 2026-09-06. The clinic publishes a non-insured treatment information page under the statutory heading (in translation) 'Non-covered treatment fees are disclosed under Article 45 of the Medical Service Act and Article 42-2 of its Enforcement Rule', and the schedule itself is four images that carry a full itemised table: crowns, core & post, inlays, resin fillings, tooth whitening, document issue, dentures, implants and bone grafting, orthodontics, paediatric, and TMJ & Botox, with a won figure against every line. The research pass could not see it because the site is a JavaScript application and the tables are images. [w3] 3/3
✗ 스케일링 가격 명시 The fee table was read in full and has no scaling line. Scaling is a covered benefit in Korea, so its absence from a non-covered schedule is expected. [w3] 0/2
✓ 충전 가격 명시 Resin filling: anterior 1 surface 100,000; 2 surfaces 150,000; 3 or more surfaces 200,000; posterior 1 surface 80,000; 2 surfaces 150,000; 3 or more surfaces 300,000 won. [w3] 2/2
✓ 크라운 가격 명시 Crowns: Gold 600,000; PFM 350,000; zirconia 500,000 anterior / 450,000 posterior; all-ceramic 500,000 won. Inlays and onlays are listed separately (gold inlay 450,000, ceramic inlay 300,000). [w3] 2/2
✓ 임플란트 가격 명시 Implants and bone grafting: DIO PFM 750,000; DIO zirconia 800,000; Osstem zirconia 1,000,000; DIO all-ceramic 900,000; Osstem all-ceramic 1,100,000; DIO Full Arch 8,000,000 per arch; Osstem All-On-X 8,500,000 per arch; standard bone graft 300,000; maxillary sinus bone graft 500,000 won. [w3] 2/2
✗ 상담 가격 명시 The fee table was read in full and carries no consultation or examination line. The nearest entry, orthodontic diagnosis 100,000, is a fee for orthodontic diagnostic records rather than for an appointment. [w3] 0/2
✗ 엑스레이 / 영상 촬영 가격 명시 The fee table was read in full and carries no imaging line. The document issue section prices copies of existing records (medical record images on CD 10,000, DVD 20,000), which is the fee for a copy, not the price of taking a scan. [w3] 0/2

평판 및 리뷰

공개된 리뷰 신호. Google 평점은 베이즈 사전확률(평점 4.0, 가중치 25)로 보정되어, 소수 리뷰의 5.0점이 수백 건 리뷰의 4.8점을 앞서지 않도록 합니다.

◐ Google 평점(베이즈 보정) Star histogram read live on 2026-09-06 from the place page: 4 five-star, 0 four-star, 0 three-star, 0 two-star, 0 one-star. The buckets sum to 4, matching the 4 in the place-page header exactly, and the weighted mean 5.000 reproduces the published 5. [gmp1] 4/6
◐ Google 리뷰 규모 as of 2026-09-26; previously 4 [dier-dental-daejeon-gbp-2026-09-26] 0.5/3
✓ 리뷰 최신성 The newest review visible is 2 months old, which proves the within-3-months bucket and no better. Sample: the 3 reviews Google Maps renders on the place page in its own relevance order. A newest-first sort was not available; a re-check on the Reviews tab returned the same three reviews, so no fresher slice is available. [gmp1] 3/3
✗ 치과가 리뷰에 응답 The Google listing is unclaimed (it offers "Claim this business"), so no owner replies to reviews (read 2026-09-26). [dier-dental-daejeon-gbp-2026-09-26] 0/2
✓ 반복되는 불만 없음 No low ratings to repeat a complaint: 1★ 0 / 2★ 0 / 3★ 0 / 4★ 0 / 5★ 19 on Google. [dier-dental-daejeon-deepen] 2/2

✗ 활성 Facebook 존재 The clinic's Facebook page has had no post since December 2015 and has one review; the clinic's website dier.kr is its working channel. [dier-dental-daejeon-presence] 0/1
✗ TripAdvisor 존재 No TripAdvisor listing found via its search for "DIER Dental Clinic Daejeon" and "DIER Dental"; the clinic's site does not link to TripAdvisor (checked 2026-10-05). [dier-dental-daejeon-tripadvisor] [dier-dental-daejeon-tripadvisor-2] 0/0.5
✓ 기타 리뷰 플랫폼 Has its own place page on Naver Place, South Korea's main local review platform (551 visitor reviews, 173 blog reviews). [dier-dental-daejeon-platforms] 0.5/0.5

✓ 교정치과 The site publishes orthodontics with pages for clear aligners, lingual, partial, protrusion and crowded-tooth treatment; the roster names a Ministry of Health and Welfare board-certified orthodontist, Gu Hyeon-jeong; and the fee table prices full ceramic, full lingual, partial and retention treatment. [w1] [w2] [w3] 2/2

Each service has its own page setting out what the treatment is, who it suits, how the process runs and a frequently-asked-questions block - for example the full-arch implant page explains the digital CT and simulated-surgery planning and the same-day fixed temporary bridge. [w1] 1/1
