Blue marks the lower price only where every compared price is quoted the same way (a monthly price in US dollars); prices quoted in another currency, as a one-time fee or as a provider-set range are shown exactly as stated and never converted. Adverse-event figures are raw counts of reports filed with the FDA, not rates (what the reports mean). Each spec value opens that brand's spec sheet, and its numbered sources verify the specs as a set. None of this is a recommendation: the right choice depends on your case, your budget and, above all, an in-person exam by a dentist or orthodontist.

The bottom line

InvisibleBraces is an informational data platform, not a dentist, an orthodontist, or a seller of aligners. Nothing here is dental or medical advice, a diagnosis, or a recommendation to start, stop, or change any treatment. At-home clear aligners are not right for every case, and moving teeth without an in-person exam carries real risk. Data is aggregated from public sources and each brand's own terms and can be incomplete or out of date. Always consult a licensed dentist or orthodontist and confirm current prices and terms with the provider.

Some outbound links on this site are referral links. If you sign up or buy through one, we may earn a commission at no extra cost to you. It never changes the price you pay or the underlying data. Partner status is one bounded, disclosed signal in how we order results: all else equal it can lift a partner above a comparable option, but it is capped so a clearly cheaper or better-reviewed option still ranks first, and every partner is labeled.

Wear schedule

Spec sheet
Start method
Taken by the dentist in the practice: an intraoral scan (3Shape, iTero, Cerec or STL files accepted) or PVS impressions, with x-rays and photos; there is no at-home kit.
In-office; the provider captures a Primescan intraoral 3D scan plus an x-ray, and the case is planned in SureSmile software and produced at the Dallas-area TechCenter
Material
Zendura FLX, a dual-shell material (hard outer shell, elastomeric middle layer), 0.76 mm (0.030 in), per 6MS; the FDA summary describes a thermoformed polyurethane-polyester composite.
Essix ACE plastic (Dentsply Sirona), a clear aligner material noted for clarity and durability that holds shape for up to about 14 days
Retainers
Not included in the patient tray kit; the dentist orders removable retainers from 6MS after treatment and sets their price
SureSmile Retainer available through the provider, indicated after aligner therapy to maintain alignment and prevent relapse
Whitening
Not published
SureSmile Whitening Kit offered at the end of treatment (included in the complete-case package alongside VPro)
Refinements / touch-ups
Up to 2 refinements within 2 years are included in the 6MS Invisible Aligners product (aligner page); a no-charge upgrade to a braces solution is offered to the dentist if braces would produce a better outcome.
Unlimited refinements included for up to 3 years from first aligner production under the flat-rate provider pricing; company states 3 of 4 cases need no refinements
Guarantee
No patient guarantee in the current terms: a limited warranty to the dentist covers defects in material and workmanship, not the outcome
Provider-facing flat-rate pricing with unlimited refinements for up to 3 years is the core assurance; any patient-facing satisfaction guarantee is set by the individual provider
Clinical oversight
In-office: a trained dentist examines, prescribes, fits and monitors; 6MS specialists prepare the plan, overseen by its orthodontists, and the dentist approves it
Doctor-directed with required in-office visits about monthly to collect new trays and monitor progress
Financing
Set by each practice
Provider-set in-office payment plans; no brand-run consumer financing (provider pays Dentsply a flat case rate)
HSA / FSA
The brand's cost page says HSA or FSA accounts can help offset the cost; acceptance is the practice's decision
Generally HSA/FSA eligible as orthodontic treatment; depends on the provider and plan
Insurance
Some dental plans may cover part of treatment (brand's cost page)
Often covered under orthodontic benefits; coverage varies by plan and provider
Availability
United States and United Kingdom through trained dentists (the company says its providers are in over 50 countries, without separating braces from aligners)
United States, Australia (Dentsply Sirona Australia offers it to dentists) and other international markets through Dentsply Sirona-authorized dental providers
Headquarters
Carrollton, Texas, United States
Charlotte, North Carolina, USA (aligners fabricated at the SureSmile TechCenter in the Dallas, Texas area)
