How much does clear-aligner treatment cost, and how is it calculated?

How much does clear-aligner treatment cost, and how is it calculated?

Direct answer: There is no single price. Dental fees in Taiwan are approved by each municipality or county[F1]. The Taipei fee schedule that was checked separates clear-aligner treatment by one or two arches and three difficulty levels, with material fees charged separately[F7]. Match the items first; look at the total second.

Geographic scope: This guide is specific to Taiwan's healthcare system (National Health Insurance and Taiwan's Medical Care Act). The sections on rules, fees, and verification cite Taiwan law, locally approved documents, and the central authority's medical-device classification data; the clinical-evidence sections cite international literature. These are marked separately in the fact ledger.

Taiwan's Medical Care Act is not a rule for the reader's own country. This card uses Taiwan's system throughout.

Before you start: why this card names no brands

km is an industry-neutral knowledge layer. This card uses only the generic terms clear aligners / clear orthodontic appliances: it names no brand, compares no brand, and endorses no system[F29]. If you arrived through a brand-name search, what needs comparing is the content of a treatment plan, not a trademark. The same brand can involve different items in different cases and plans; brand-to-brand price comparison can therefore compare a number unrelated to your teeth[F29].

The Taipei fee schedule treats “Clear Aligner” and “clear orthodontic treatment” as different items[F10][F7]. Item 3-75 is a per-appliance device for a simple post-treatment irregularity caused by not wearing a retainer as directed[F10]. Items 3-76 through 3-81 are one- or two-arch clear orthodontic treatment, at general, difficult, and high-difficulty levels, and all state that material fees are separate[F7]. Thus the same everyday question can mean either a small post-treatment realignment device or a whole course of orthodontics. Their billing units differ, so they cannot be compared directly[F29].

How the charge is structured: the approved schedule already separates the items

Taiwan has no single nationwide dental price list. Taiwan's Medical Care Act Article 21 provides that medical-fee standards are approved by the municipality or county (city) authority[F1]. Institutionally, the answer to “how is it calculated?” is therefore: check how the approved schedule in the city or county where you receive care separates the items.

On 2026-08-06, this site retrieved the Taipei Department of Health's approved 「Taipei City Medical Institution Dental Fee Schedule」 (approved 17 January, ROC year 109; approval No. 北市衛醫字第 1093010058 號)[F13]. The orthodontics section supplies this structure; this card cites item names, units, and published descriptions, never unit prices.

A. Assessment and diagnosis: Item 3-50 is orthodontic consultation, including a full-mouth X-ray and at least 30 minutes of consultation with written or recorded material, but excluding examination and analysis[F6]. Item 3-51 is examination, diagnosis, and treatment planning, including examination and analysis and possible plans[F6]. Item 3-52 adds 3D craniofacial imaging from CT digital radiographs; the CT radiograph fee is included[F6]. Consultation and examination/analysis are therefore separate items.

B. Digital workflow: Item 3-72 is a digital impression from an oral scan; 3-73 creates a digital model from the scan and states that each course requires at least two models; 3-74 is digital tooth setup and states that each course needs at least one setup[F9]. These are the items often called oral scanning, modelling, and simulation. They are independent schedule items with their own stated minimum frequencies[F9]. Whether they are listed or included in a particular written quotation still depends on that document[F29].

C. Appliance and course of treatment: one-arch items 3-76/3-77/3-78 and two-arch items 3-79/3-80/3-81 are general, difficult, and high-difficulty clear orthodontic treatment, each with “difficulty criteria + material fees charged separately”[F7]. In the same schedule, fixed-appliance items 3-55 to 3-60 say that the various material preparations and technical execution are included; the clear-aligner items say material fees are separate[F8][F7]. That is a difference in this approved document, not a claim about how any clinic must bill[F29][F30].

D. During and after treatment: adjustment items 3-68/3-69/3-70 include the situation where treatment adjustment is entrusted to the institution for a patient treated orthodontically elsewhere[F11]. Removable and fixed retainers (3-65 to 3-67) are separate items, and 3-71 is post-treatment review or appliance adjustment, including retainer adjustment[F11]. Put together, the structure is assessment and diagnosis → digital scan and plan → appliance (materials separate) → adjustments during treatment → retention[F29]. A quotation with only one total omits the useful question: what does each of these five parts include and exclude?

Why someone else's number cannot be applied to you

The Taipei schedule defines general, difficult, and high-difficulty clear orthodontics by clinical conditions, not subjective impressions[F7]. General means normal incisor overjet and overbite, no interjaw skeletal discrepancy, and mild crowding. Difficult includes overjet or overbite greater than 3 mm, an interjaw discrepancy, moderate crowding, or crossbite. High difficulty includes severe mandibular prognathism, overjet or overbite greater than 7 mm, severe interjaw discrepancy, severe crowding, skeletal open bite, or skeletal crossbite[F7]. “Clear aligners” is therefore not one uniform thing in the schedule. Without arch count, difficulty level, and material-fee treatment, an online number cannot be matched to your circumstances[F29]. This card gives no price range and judges no price[F30].

The Taipei note also says that unlisted items may not exceed that city's medical-centre fee standards; a higher institutional fee schedule needs Taipei Department of Health approval under the Medical Care Act; and later NHI-covered items follow NHI payment rules, with non-covered items approved within twice the medical-centre-level NHI payment standard[F12]. Taiwan's Medical Care Act Article 22 requires an itemised receipt and prohibits charging above or creating items contrary to fee standards[F2]. The tool the system gives you is item checking, not price shopping[F29].

Why NHI does not pay: a different statutory basis from another meaning of “dental braces”

Article 51 of Taiwan's National Health Insurance Act lists non-covered services. Subparagraph 3 includes non-traumatic-treatment orthodontics[F5], which is the basis for orthodontics generally being self-paid. Whether a particular case is traumatic-treatment orthodontics, and whether related services are covered, remains subject to current NHI Administration rules and review; this card makes no individual determination[F5]. A prosthetic crown meaning of “dental brace” is instead covered by subparagraph 11's different list of dentures, artificial eyes, glasses, hearing aids, wheelchairs, crutches, and other non-active-treatment appliances[F5]. They are different provisions and different things.

What the appliance is: a Class 2 medical device

In Taiwan's regulatory system, a clear orthodontic appliance is a regulated medical device, not an ordinary consumer product[F14][F15]. A 2026-08-06 search for 矯正器 in the medical-device classification database returned four records, including F.5470, “Orthodontic plastic bracket and aligner,” Class 2[F14]. Its scope describes a thermoplastic device for treating mild malocclusion that can gently move teeth continuously, may work with patient-scanning software or hardware, and is designed and made as a series from a digital dental scan[F14].

For costs, this supports three carefully limited inferences[F29]: it is a series rather than a one-off appliance, so the written document should make the number of appliances and remakes intelligible; its design/manufacture relies on a patient scan, so scanning and design are manufacturing prerequisites rather than optional extras; and the device classification's “mild malocclusion” wording cannot be substituted for the next section's international clinical literature on “mild to moderate” cases[F14][F16][F29]. Taiwan's Medical Device Management Act Article 25 requires manufacture or import to undergo registration and approval, except announced items handled by listing[F15]. This card does not decide whether any product is lawful and recommends no product[F30].

What the literature says: indication range, treatment length, and why more aligners may be added

These are population-level research findings, not a prediction for your own teeth and not a quality metric for any clinic[F30].

Indication range

A 2022 overview, searched to 2021-07-15, identified 361 potentially eligible reviews and included 18 after excluding irrelevant or low-quality reviews. It found clear-aligner treatment effective for mild-to-moderate malocclusion, with inferior results in severe cases or for specific tooth movements; overall evidence was moderate and further high-quality randomised trials were needed[F16].

A 2025 review and meta-analysis, searched to 2024-10, selected 21 randomised trials from 600 records involving 970 participants. It found no significant difference in ABO objective grading, Little Irregularity Index, or PAR scores between clear and fixed appliances, but rated the overall evidence low and limited this conclusion to simple non-extraction malocclusion[F17]. Another 2025 review, searched to 2025-02, included 15 trials and 1084 patients. It found no significant quality or duration difference in non-extraction cases (sensitivity analysis suggested shorter clear-aligner duration), whereas in extraction cases fixed appliances had better treatment quality, attributed to better tooth-movement control. Case complexity and patient compliance should guide appliance choice[F18].

For extraction cases specifically, a 2026 review searched to 2025-04-19 and included 20 studies: 536 aligner and 173 fixed-appliance patients. Predicted and achieved movements differed significantly, including excessive mesial tipping of upper first molars (mean difference -6.08°, 95% CI -7.89 to -4.26) and under-retraction (-1.93 mm, 95% CI -2.15 to -1.71). The authors describe biomechanical limits in precise root control and bodily movement, requiring strategic overcorrection and adjunctive mechanics[F19]. If extraction, skeletal anchorage, or another adjunct is needed, the plan contains additional procedures; whether and how those are charged must be checked item by item in writing[F29]. This card has not verified whether each local schedule contains corresponding orthodontic-adjunct items, and does not infer that they are always separate or always included[F30].

Treatment length and visits

Orthodontics extends over time, and fee structure commonly relates to time and visits[F29]. A 2016 systematic review included 25 studies. Across 22 combinable studies with 1089 participants, fixed appliances averaged 19.9 months (95% CI 19.58–20.22); five studies averaged 17.81 required visits. In prospective university-setting studies, comprehensive orthodontics averaged under two years[F25]. This is an average in that research population, not a promise for any individual[F25].

Will clear aligners be faster? A 2024 review searched to 2023-06, included 10 studies (6 RCTs) from 3537 initial records, rated the evidence low under GRADE, and found similar duration in mild-to-moderate crowding. It did not meta-analyse because inconsistency was high, and only one study used extraction treatment[F24]. “Which is faster?” therefore does not currently have high-grade evidence behind it[F24][F18].

Why refinement may be needed

Additional appliances after the first series are often called refinement. A 2026 review of 20 studies found that the term was defined heterogeneously: refinement or additional aligners, finishing phases, refinement plans, midcourse correction, and first-refinement scans were all grouped together. Refinement burden may be associated with malocclusion complexity, extraction treatment, interproximal reduction strategies, severe spacing, larger correction sequences, and movement-specific limits; rotations, intrusion, vertical correction, transverse expansion, and selected anterior movements had lower predictability[F20]. Refinement after the first series is a multifactorial clinical outcome, not one uniform finishing procedure; remote monitoring appeared to reduce visit burden but did not consistently reduce refinement need[F20]. Because even the literature lacks one definition, the number of added appliances and how remakes are charged can be written differently by different institutions. Ask line by line; do not guess from the total[F29].

Attachments are the small composite projections on aligners. A 2022 review included five clinical trials, all at medium risk of bias. Attachments mostly improved anterior root torque, rotation, mesiodistal movement, and posterior anchorage, but some results conflicted or were not statistically significant; more trials are needed on number, size, shape, and position[F21]. Their number and position are determined by the dentist's treatment plan; this card offers no configuration advice[F30].

Risk factors to know before deciding

• The indication has limits: the Taiwan device classification describes treatment for mild malocclusion[F14], while the review evidence supports mild-to-moderate malocclusion and reports poorer outcomes in severe cases or specific movements[F16].
• Extraction-case control is limited: predicted and achieved movements differed; root control and bodily movement have biomechanical limits. `root divergence` means roots failing to remain parallel, not root branching, and anchorage loss were prevalent in the review[F19]. Fixed appliances had better treatment quality in extraction cases[F18].
• Some movements are less predictable: rotation, intrusion, vertical correction, transverse expansion, and selected anterior movements[F20].
• Patient cooperation matters: clear aligners are aesthetic and removable, and the review says case complexity and patient compliance should guide appliance choice[F18].
• Root resorption can still occur: a 2025 review/meta-analysis included 10 studies: 286 patients and 1476 incisors in the clear-aligner group, 289 patients and 1487 incisors in the fixed-appliance group. Except for mandibular lateral incisors, external apical root resorption was significantly less with clear aligners. Patient-level mean differences ran from -0.64 mm (95% CI -0.90 to -0.38) for maxillary central incisors to -0.26 mm (95% CI -0.43 to -0.09) for mandibular central incisors. Heterogeneity was generally high, and clinical significance still needs clarification[F22]. This is a study-level comparison, not “no root resorption,” and not a sole reason to choose an appliance[F22].
• Periodontal differences may be smaller than expected: a 2023 umbrella review of four meta-analytic systematic reviews found differences in plaque, gingival, bleeding-on-probing, long-term probing-depth, and short-term recession measures, with a slight tendency toward healthier conditions with clear aligners. Even when statistically significant, the authors judged them clinically negligible and the periodontal impact comparable[F23].
• Retention is part of treatment: teeth tend to move back, so fixed or removable retainers are used for stability[F26]. A 2023 Cochrane update included 47 studies and 4377 participants; evidence was low to very low certainty and could not establish one better retention approach[F26]. This card gives no general retainer-wearing duration.
• Evidence certainty is limited: authors rated many comparisons in this card low or moderate certainty[F16][F17][F24]; population estimates cannot determine an individual's result[F30].

Pre-visit checklist: eight questions for a written quotation

1. Is this for one arch or two, and which approved difficulty tier and criteria apply?[F7]
2. Is the appliance itself (material fee) included or separate, and how is a separate fee calculated?[F7]
3. How many aligners are planned? If refinement is needed after the first series, how are additional appliances and plan changes charged, and is there a limit?[F20]
4. Are assessment, examination and planning, digital scan/modelling, and digital setup separate items or included in the total?[F6][F9]
5. How many adjustment visits are included? What happens with extra visits, a lost/damaged appliance, or a detached attachment?[F11][F29]
6. Are extraction, skeletal anchorage, or other adjunctive procedures needed, and are they separate?[F19]
7. Does the quotation include retention: retainer fabrication, retention visits, and damaged or lost retainers?[F11][F26]
8. Will the receipt itemise the fee items and amounts, and how will added fees be explained before a plan changes?[F2][F3]

Taiwan's Medical Care Act Article 81 requires a medical institution to explain condition, treatment policy, procedure, medication, prognosis, and possible adverse reactions[F3]. You are entitled to answers to these questions.

How to verify a quotation

• Check the approved fee schedule of the health authority where you will receive care. Local authorities approve dental fees[F1]. The Taipei schedule checked by this site does contain clear-orthodontic items 3-76 through 3-81 and the orthodontics section[F7][F13], so this route yields relevant material for this subject. Other cities and counties publish their own schedules.
• Taiwan's NHI medical-device price-comparison site does not show dentistry. Two query routes were checked in a browser; neither category list contained dental items and the visible page text did not contain the character for “tooth”[F27]. On this site's check, it cannot be used to look up orthodontic fees.
• Return to the written document. A public database not listing an item does not mean there is an official price. Check the clinic's written quotation and receipt item by item[F2][F29].
• The appliance database verifies regulatory identity, not price. Clear aligners are F.5470, Class 2[F14]; manufacture or import requires registration/approval or announced listing[F15]. The database supplies classification, not any price[F30].

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

Compliance note

This is health education under Article 87 of Taiwan's Medical Care Act[F4], not medical advertising. It recommends no clinic, brand, or comparison and gives no amount or price range. Orthodontics is long-term; clear-aligner appliances have indication limits, restrictions, possible adverse effects, and contraindications, including root resorption, less predictable movements, and the need for patient wear compliance. Actual treatment and outcomes vary by person and require a dentist's assessment. This card gives no legal view on insurance claims or contract terms; those depend on the insurance policy and contract terms.

Every clinical statement in this article is mapped line by line to its cited source (see the sources and evidence chain below). It has not been clinically reviewed by a licensed practitioner. This is health information, not individual advice; assessment by a clinician is required.
