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: Angel Aligner $2,500-6,500 (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 Data is aggregated from public sources and each brand's own terms and can be incomplete or out of date.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.

Product lines
Angel Aligner clear aligners
6MS Invisible Aligners, 6MS Relapse Aligners, 6MS Mixed Appliance
Wear schedule
Standard clear-aligner wear of 20 to 22 hrs/day; tray-change interval set by the treating doctor (not fixed by the brand)
Trays changed every 2 weeks; wear hours not published
Spec sheet
Start method
In-office digital scan at an orthodontist or dentist; Angelalign fabricates custom trays with an advertised ~10-day turnaround
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
masterControl S (MCS), a soft multi-layer polymer (3-layer construction: a soft elastic inner layer between two firmer outer layers) designed for gentle, sustained force
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
Bundled by the provider; some offer lifetime retainer replacement (e.g. via a practice 'Forever Aligned Club' membership)
Not included in the patient tray kit; the dentist orders removable retainers from 6MS after treatment and sets their price
Whitening
Not published (provider-dependent; not a standard brand inclusion)
Not published
Refinements / touch-ups
Refinement trays typically included in the provider's all-inclusive fee
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
No published manufacturer smile guarantee; any guarantee is set by the treating provider
No patient guarantee in the current terms: a limited warranty to the dentist covers defects in material and workmanship, not the outcome
Clinical oversight
Direct in-office supervision by a licensed orthodontist or dentist throughout treatment
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
Provider-arranged; many practices offer payment plans from about $99/month at 0% interest (some through Cherry or CareCredit)
Set by each practice
HSA / FSA
Generally HSA/FSA eligible in the US as qualifying orthodontic treatment
The brand's cost page says HSA or FSA accounts can help offset the cost; acceptance is the practice's decision
Insurance
Often partially covered by dental/orthodontic insurance (typically $1,000 to $2,500 of the total)
Some dental plans may cover part of treatment (brand's cost page)
Availability
US (via orthodontists and dentists since August 2023) and Australia (Orthodontic Aligners Australia Pty Ltd, its Australian company), plus 40+ countries globally; company reports 1M+ smiles treated worldwide
United States and United Kingdom through trained dentists (the company says its providers are in over 50 countries, without separating braces from aligners)
Headquarters
Shanghai, China (manufacturing via Wuxi EA Medical Instruments Technologies, Wuxi, China)
Carrollton, Texas, United States
