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

What actually differs

  • Neither is marked lower, since only monthly prices quoted in US dollars are ranked against each other: Orthocaps ~€1,500-8,000 (provider-set) and Six Month Smiles Provider-set.

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 Data is aggregated from public sources and each brand's own terms and can be incomplete or out of date.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.

Spec sheet
Start method
In-office at a certified orthocaps provider: A-silicone impressions (or an intraoral scan), bite registration and X-rays taken by the orthodontist or dentist; a 3D iSetup plan is created and approved before manufacturing (first aligners in about 2 to 3 weeks)
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.
Material
TwinAligner 2-component thermoplastic with a soft inner layer and a firmer outer layer: a soft, thin DAYcap and a thicker NIGHTcap. Elastic thermoplastics manufactured in Germany and biocompatibility-tested to European standards (specific resin name and BPA content Not published)
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.
Retainers
Not published (post-treatment retention is arranged by the treating practice)
Not included in the patient tray kit; the dentist orders removable retainers from 6MS after treatment and sets their price
Whitening
Not published
Not published
Refinements / touch-ups
Not published (additional aligners and plan revisions are handled per case by the treating orthodontist; the maker issues a 3D Treatment Evaluation Report at the end of each phase)
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.
Guarantee
Not published
No patient guarantee in the current terms: a limited warranty to the dentist covers defects in material and workmanship, not the outcome
Clinical oversight
Doctor-directed: treatment is prescribed, fitted and monitored by a certified orthocaps orthodontist or dentist; the case is planned from an iSetup 3D simulation and each phase closes with a Treatment Evaluation Report (TER). Not available direct-to-consumer.
In-office: a trained dentist examines, prescribes, fits and monitors; 6MS specialists prepare the plan, overseen by its orthodontists, and the dentist approves it
Financing
Not published (arranged by the individual practice)
Set by each practice
HSA / FSA
Not published (handled by the treating US practice where applicable)
The brand's cost page says HSA or FSA accounts can help offset the cost; acceptance is the practice's decision
Insurance
Not published (depends on the patient's plan and the treating practice)
Some dental plans may cover part of treatment (brand's cost page)
