F-Units (fact ledger)

Each entry states the source, confidence, basis, period, geo, and caveat. Basis hierarchy: law > official_statement > clinical_guideline > peer_reviewed > textbook.

• F1｜confidence: high｜basis: internal_dataset (S23; not a medical claim)｜period: GSC retention window (from 2025-03-22)｜geo: TW｜Topic-selection basis = reconciliation of search data from 14 clinic sites, 14 query terms across 4 sites, item-by-item reconcilable｜caveat: internal data; not included in the visible layer at publication.
• F2｜confidence: n/a｜basis: structural synthesis (editorial framework, S24; not a factual claim)｜geo: universal｜The “six-part cost breakdown” framework, the boundary with the fixed-denture cost card (this card = one crown with the root remaining; the three routes and bridges = KM-DENTAL-03), and the narrative structure of “two common clinical situations” are this site's editorial definitions, not external facts.
• F3｜confidence: n/a｜basis: evidence-gap statement (editorial; not awaiting verification)｜geo: universal｜This search did not obtain citable evidence for the following, so this card does not state: ① any monetary amount, range, or market price; ② an individual forecast of how long a crown can be used; ③ Taiwan-local crown-survival statistics; or ④ the content and effect of warranty terms (a contractual matter, not a medical question; this site gives no legal opinion).
• F4｜confidence: medium｜basis: peer_reviewed (retrospective cohort study, PMID 11941351)｜period: treatment data from 1985–1996; published 2002｜geo: universal｜span: 「When tooth type and radiographic evidence of caries at access were controlled, the final Cox model showed that endodontically treated teeth not crowned after obturation were lost at a 6.0 times greater rate than teeth crowned after obturation (95% confidence interval: 3.2 to 11.3).」「Kaplan-Meier survival estimates were generated for the 203 teeth that satisfied study inclusion criteria.」「Within the limitations of this study, a strong association between crown placement and the survival of endodontically treated teeth was observed.」｜caveat: retrospective, single university institution, non-random allocation; association does not equal causation; data are old.
• F5｜confidence: high｜basis: peer_reviewed (Cochrane systematic review, PMID 26403154)｜period: 2015 update (pub3), searched to 2015-03-26｜geo: universal｜span: 「We included one trial, which was judged to be at high risk of performance, detection and attrition bias.」「There was no clear difference between the crown and composite group and the composite only group for non-catastrophic failures of the restoration」「The quality of the evidence for these outcomes is very low.」「There is insufficient evidence to assess the effects of crowns compared to conventional fillings for the restoration of root-filled teeth.」｜caveat: Version-currency check (2026-08-06): a PubMed search using the original title returned 3 records: the 2012 first edition (pub2), the 2015 update (pub3), and a 2016 commentary; no update was found. This card cites the current version, but its search window ends in 2015 and must be read with the newer reviews in F6 and F10.
• F6｜confidence: high｜basis: peer_reviewed (systematic review・meta-analysis, PMID 38949036)｜period: searched to 2023-01; published 2024｜geo: universal｜span: 「The pooled survival rates at 4-7 years and 8-20 years of root-filled posterior teeth regardless of tooth type was 91% (95% CI, 0.85; 0.95) and 87% (95% CI, 0.77; 0.93), respectively.」「The prognostic tooth-related factors mentioned in the included studies were (i) remaining coronal tooth structure, (ii) ferrule, (iii) crown-to-root ratio (iv) tooth type and location (v) periodontal disease (vi) proximal contacts and (vii) cracks.」「However, there is a paucity of evidence, and more research is needed in this area.」｜caveat: 20 studies in the meta-analysis, mostly retrospective; the prognostic-factor portion is a narrative synthesis, not a pooled estimate; a 2026-08-06 search found no updated survival meta-analysis for this question.
• F7｜confidence: medium｜basis: peer_reviewed (systematic review・meta-analysis, PMID 34530058)｜period: searched 2021-07-13; published 2021｜geo: universal｜span: 「The random effects model for subgroup meta-analysis revealed failures for posterior RFT increased with decreasing numbers of remaining walls.」「Failures for 0 remaining walls were 23% (95% CI = 10% - 36%) and for one remaining wall 15% (CI: 3% -26%), irrespective of follow-up times.」｜caveat: population restricted to root-canal-treated teeth restored with a fibre post and a single crown; only 5 studies were included. It cannot be generalised to all crowns or cases without a post and core; a 2026-08-06 search found no update.
• F8｜confidence: medium｜basis: peer_reviewed (systematic review・meta-analysis, PMID 41601347)｜period: published 2026｜geo: universal｜span: 「To systematically review and meta-analyze clinical, in vitro, and finite-element studies assessing how ferrule height, width, and circumferential extent influence fracture resistance and survival of endodontically treated teeth.」「Thirty-three primary studies (6 clinical, 18 in vitro, 9 finite-element) were included.」「Ferrule height ≥ 2 mm significantly improved fracture resistance (MD +165 N; 95% CI: 110-215). Ferrule presence increased clinical survival (RR 1.34; 95% CI: 1.12-1.59). Dentin thickness ≥ 1 mm and complete 360° ferrules provided the most favorable reinforcement, while partial ferrules with ≥ 2 opposing walls remained beneficial.」「These findings should be interpreted within the context of variation in study designs and reporting quality.」｜caveat: Version-currency check (2026-08-06): this paper is later than F9 (2024). A 2026-08-06 PubMed search for ferrule + SR/MA found no later review on the same question. But only 6 of its 33 included studies were clinical; the rest were in-vitro experiments and finite-element analyses, so clinical extrapolation must be cautious. This card therefore also retains F9, which includes clinical studies only.
• F9｜confidence: medium｜basis: peer_reviewed (systematic review・meta-analysis, clinical studies only, PMID 38216376)｜period: published 2024｜geo: universal｜span: 「Direct analysis of success rates (2 studies, 123 teeth) showed a significant increase in success when a uniform circumferential ferrule was present (RR=1.28, 95% CI: 1.06, 1.54, P<.05).」「However, indirect analysis of survival and success rates (8 studies, 407 teeth) indicated no significant differences in outcomes between the ferrule and no ferrule groups (P>.05).」｜caveat: direct comparison includes only 2 studies and 123 teeth; the authors explicitly call for more high-quality research. Same anchor as KM-DENTAL-03.
• F10｜confidence: medium｜basis: peer_reviewed (clinical literature review, PMID 33128279)｜period: searched to 2020-07; published 2021｜geo: universal｜span: 「Whilst there is established consensus on the importance of the ferrule effect on the predictable restoration of root filled teeth, other factors, such as residual tooth volume, tooth location, number of proximal contacts, timing of the definitive restoration and the presence of cracks, have been reported to influence restoration and tooth survival.」｜caveat: narrative literature review, not a meta-analysis.
• F11｜confidence: medium｜basis: clinical_guideline (society position statement, PMID 34378217)｜period: published 2021｜geo: universal｜span: 「This position statement on the restoration of root filled teeth represents the consensus of an expert committee, convened by the European Society of Endodontology (ESE).」「The scientific basis of the recommendations made in this paper can be found in a recently published review article」｜caveat: Full text could not be retrieved (paywall). This card only uses the abstract to state the existence and position of the statement and cites none of its individual clinical recommendations. Its underlying scientific review is F10.
• F12｜confidence: medium｜basis: peer_reviewed (systematic review; no meta-analysis, PMID 37549135)｜period: searched 1946 to 2022-04; published 2024｜geo: universal｜span: 「A total of eleven studies met all predetermined search criteria.」「Survival results for full veneer crowns were reported at 87.8% at over two years, 95.1% at three years, and 84% - 97.73% at five to ten years.」「The data suggest that the use of onlays instead of full veneer crowns in the restoration of endodontically treated posterior teeth is favourable in the short to midterm.」｜caveat: different study results are listed as ranges; no pooled estimate was made, and follow-up periods and outcome definitions vary. The lower range bounds for two- and three-year onlay survival (95%, 90.7%) are cited in the body; the upper bound is complete survival in an individual study and is not repeated word for word here.
• F13｜confidence: medium｜basis: peer_reviewed (systematic review・meta-analysis, PMID 35835608)｜period: published 2022｜geo: universal｜span: 「The overall failure rate that emerges is 0.087 with a ratio of 121/1254, I2 80 % p-value< 0.001.」「Moreover, by meta-regression with covariates the follow-up period reports a coefficient of 0.013 with a P-value< 0.001.」「Besides the survival rates of indirect adhesive restorations on endodontically treated posterior teeth, it was highlighted that the majority of failures appeared restorable.」｜caveat: high heterogeneity (I² 80%); the pooled weighted estimate (0.087) and raw event proportion reported alongside it (121/1254) use different measures and are separately labelled in the body; the time trend comes from a meta-regression coefficient, not direct subgroup comparisons.
• F14｜confidence: high｜basis: peer_reviewed (systematic review・meta-analysis, PMID 41489982)｜period: published 2026; search window 2014–2024; five-year survival estimates｜geo: universal｜span: 「Sixty-four studies met inclusion, reporting on 3,509 metal-ceramic and 8,051 all-ceramic SCs.」「Five-year survival rates were: 98.5% for monolithic lithium-disilicate reinforced glass-ceramic, 97.3% for veneered densely-sintered zirconia, 97.1% for metal-ceramic, 96.8% for monolithic densely-sintered zirconia, 95.7% for veneered leucite/lithium-disilicate reinforced glass-ceramic, 94.5% for densely-sintered alumina, 94.3% for glass-infiltrated alumina, 90.4% for feldspathic/silica-based ceramic.」「Monolithic lithium-disilicate and monolithic zirconia crowns showed significantly fewer ceramic fractures and chipping compared to veneered alternatives.」「Lithium-disilicate and zirconia-based all-ceramic SCs achieve five-year survival rates comparable to metal-ceramic crowns.」｜caveat: population-level estimates with five-year follow-up; not generalisable to an individual prognosis. Same anchor as KM-DENTAL-03. Version-currency check (2026-08-06): a search for single crowns + survival + SR/MA in the 2024–2026 publication period found no later meta-analysis comparing materials for tooth-supported single crowns.
• F15｜confidence: medium｜basis: peer_reviewed (overview of systematic reviews, PMID 40750081)｜period: search updated to 2025-02; published 2025｜geo: universal｜span: 「Ultimately, 28 systematic reviews on approximately 35,000 crowns published between 2007 and 2024 were included in the qualitative analysis.」「However, substantial methodological heterogeneity, limited long-term data (>5 years), and a concentration of studies on a single product」「Nevertheless, careful interpretation is warranted due to methodological variability, material-specific differences, and insufficient long-term data for newer lithium (di)silicate systems.」「practitioners should communicate both the well-documented short- to medium-term benefits and the remaining uncertainties regarding long-term performance」｜caveat: the overview covers systematic reviews, not original studies. This card uses only its conclusion about methodological limitations and does not cite its survival figures.
• F16｜confidence: medium｜basis: peer_reviewed (systematic review・meta-analysis, observational studies, PMID 34516686)｜period: searched to 2021-01; published 2022｜geo: universal｜span: 「Electronic searches provided 10,075 records among which 20 studies were selected for systematic review and 7 studies were selected for meta-analysis.」「The meta-analysis revealed clinical and radiographic success rate ranging between 92% to 98% at different follow up periods ranging between 5 years and 20 years.」「Future high-quality randomized clinical controlled trials with a larger population are required to confirm the evidence as only observational studies were considered in this paper.」｜caveat: observational studies only and high heterogeneity; success is defined by pulpal and periapical status, not crown survival itself.
• F17｜confidence: high｜basis: clinical_guideline (narrative review commissioned by the 2017 World Workshop, PMID 29926939)｜period: published 2018｜geo: universal｜span: 「Placement of restoration margins within the junctional epithelium and supracrestal connective tissue attachment can be associated with gingival inflammation and, potentially, recession.」「Procedures adopted for the fabrication of dental restorations and fixed prostheses have the potential to cause traumatic loss of periodontal supporting tissues.」「Restoration margins located within the gingival sulcus do not cause gingivitis if patients are compliant with self-performed plaque control and periodic maintenance.」「Hypersensitivity reactions can occur to dental materials.」｜caveat: narrative review, not a meta-analysis; same anchor as KM-DENTAL-03.
• F18｜confidence: high｜basis: law (S15)｜period: current text (checked 2026-08-06)｜geo: TW｜Article 21 of Taiwan's Medical Care Act. Verbatim span: 「醫療機構收取醫療費用之標準，由直轄市、縣（市）主管機關核定之。」

How to find a clinic that provides this service

This site lists no clinics and does not recommend, rate or compare any medical institution.

To find a clinic that provides this service, use the following official lookup channels yourself —

they are maintained by the competent authorities and are more current than any list:

>

- The Ministry of Health and Welfare's medical-institution lookup: search by city or county,

township and specialty (dentistry) for institutions that have completed practice registration.

The results show the institution's name, address and registered specialty. This is the first place

to confirm whether a clinic is lawfully registered.

- The National Health Insurance Administration's contracted-institution lookup: check whether a

clinic is under contract with National Health Insurance. This determines which items are covered

and which are self-paid, and therefore what kind of fee explanation you will be given.

>

Both systems are on the respective authorities' official websites; searching for the

medical-institution lookup or the contracted-institution lookup will find them. This site does not

reproduce the URLs, because they change; use whichever entry point the authority currently publishes.

>

In an emergency, do not spend time looking up lists. If your breathing, swallowing or speech is

affected, or swelling is spreading, go to the nearest emergency department.

Chinese labels to look for on the official pages

These official systems, datasets and files are published in Chinese only. The English names above are this site's renderings; on the page itself you will see the following strings, so search for these:

Compliance note

This is health-education information under Article 87 of Taiwan's Medical Care Act[F24], not medical advertising. It does not recommend a particular institution and gives no monetary amount or price range. A single crown involves irreversible tooth preparation and has medical risks and contraindications; pulpal symptoms, ceramic chipping, loss of retention, and gingival inflammation at the margin can occur. The actual treatment approach and outcomes vary by person and require a dentist's assessment. The decision factors collected in this card are for treatment conversations and cannot replace clinical diagnosis. This card also gives no legal view on insurance claims or contract terms; related questions depend on the policy and contract terms.

Internal citation chain

• Same-family routing card (required reading): How much does one fixed denture cost? First distinguish a crown from a bridge (KM-DENTAL-03, draft). The canonical boundary between the two cards: the other card covers the three-route framework for fixed dentures, survival and complications of bridges (including cantilever and adhesive bridges), the entry point for implant-supported dentures, and clinical trials of temporary-denture loss. This card covers indication assessment for a single crown (after root-canal treatment and with extensive loss), ferrule and remaining-tooth-structure conditions, partial-coverage alternatives, complete five-year material-survival and complication data for single crowns, and the item breakdown for one crown quotation. At overlap, this card retains only one summary sentence and points to the other card rather than repeating the discussion. Both cards use the same Taiwan institutional anchors (Articles 21, 22, and 81 of Taiwan's Medical Care Act and Article 51 of Taiwan's National Health Insurance Act) and F9, F14, and F17 literature anchors. Laws and English spans are verbatim-identical as required for citation-grade work.
• Same-family decision card: Must a cavity be filled? How are fillings done? (KM-DENTAL-12, draft). If your situation is “the cavity is not yet extensive enough to need a crown,” this card covers the restorative-level choices and criteria. The present card begins when tooth structure is extensively lost and a crown has been suggested.
• Preparatory-procedure card: What is crown lengthening? Cost, insurance, and whether it hurts (KM-DENTAL-17, draft). One path mentioned in part 2 of this card's cost components, when an adequate ferrule cannot be achieved, is the procedure discussed there. See that card for indications and cost components.
• Meaning-disambiguation card: How much does a “dental cap” cost? Orthodontic braces and a prosthetic crown are not the same thing (KM-DENTAL-08, draft). Readers searching “brace price” when they actually mean an orthodontic appliance should begin with that card.
