Spec sheet
Start method
In-office clinical impressions or a 3D intraoral scan taken by the treating dentist or orthodontist
In-office consultation with a licensed dentist or orthodontist, including x-rays and a 3D intraoral digital scan; the provider designs the plan and fits the aligners
Material

TruGEN and TruGEN XR (Ormco), a 0.75mm polymer free of BPA, latex, phthalates, and mercury; marketed as clearer, more stain-resistant, and better contoured to the tooth than the leading brand
Retainers
Not published
Spark Retainers (launched 2025) available through the provider; retainers required after treatment to prevent relapse (provider-set cost)
Whitening
Not published
Not published as a bundled consumer offering; whitening is at the provider's discretion (the TruGEN material is marketed as stain-resistant)
Refinements / touch-ups
Not published (arranged through the treating provider)
Provider-managed additional trays; TruGEN and TruGEN XR are available for both primary and refinement stages. Refinement policy and cost are set by the treating provider (not published as a fixed manufacturer allowance)
Guarantee
Not published
No manufacturer-level consumer guarantee; any satisfaction or results guarantee is set by the individual provider
Clinical oversight
In-office: prescription-only, fitted and monitored by a treating dentist or orthodontist. Each case is planned manually to a tenth of a millimetre by the F22 team at the F22 Centre in Padua, and clinicians are supported by a tutor orthodontist from the University of Ferrara School of Orthodontics.
Doctor-directed with in-person progress visits about every 4 to 8 weeks (some providers add remote monitoring between visits)
Financing
Not published (arranged through the treating provider)
Provider-set in-office payment plans (review examples cite roughly $125 to $167/month depending on term); no brand-run financing program
HSA / FSA
Not applicable (Italy/Europe-based; no US direct-to-consumer channel)
Generally HSA/FSA eligible as orthodontic treatment (confirmed accepted per NewMouth review); depends on the provider and plan
Insurance
Not published (varies by country and provider)
Often covered under orthodontic benefits, though some dental plans treat adult aligners as cosmetic; coverage varies by plan and provider

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.

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.
