| How it startsAn impression kit or a scan records the teeth. Check whether a dentist examines you in person. | A free visit at an Impress clinic in Chicago, New York, San Francisco or Seattle. | An exam and scan at a CandidPro dentist's office. | |
| Check-ins and monitoring | In a clinic to start, fit and finish, with photo check-ins in the app between visits. | About three office visits on average, with photo scans from home every 7 to 14 days. | |
| Who plans and supervises | A dentist or orthodontist at the clinic. The site does not name them. | Your dentist, with a US-licensed Candid orthodontist reviewing the plan on Comprehensive cases (not Elements). | |
| Cost | |||
| Treatment priceCheck whether a price covers one arch or both, and what it includes. | Set after assessment$3,499 to $5,599 The clinician decides which plan applies after an assessment. The provider does not say whether this covers one arch or both. Checked October 26, 2026 | Practice fees$1,350 to $4,500 Practices publish CandidPro fees from $1,350 for a small Elements case to a $4,500 average; Candid says providers average about $4,000. These are fees at practices we checked, not the provider's price; your practice sets yours after an examination. Checked October 26, 2026 | |
| Aftercare | |||
| Retainers | Sold separately. Impress's retainer subscription is from $599 a year; another clinician can also make retainers. | PermaForm retainers, ordered through your dentist at the dentist's price. | |
| RefinementsConditions often apply. The review has the detail. | All the Invisalign aligners you need are included, along with attachments and IPR. | On Comprehensive cases, unlimited and free to the practice for three years from the first shipment; not included with Elements. Ask whether your fee passes that on. | |

In alphabetical order. This is not a ranking.
Who is included. A provider can be compared when we have a current review, new patients can start with it in the US, and we could confirm how treatment starts and how progress is checked. A missing price never rules a provider out: practice-set fees are shown as practice fees or as a quote. Being listed is not a recommendation.
Providers that have closed, changed or could not be confirmed are listed under Looking for another provider? on the reviews page. Prices and terms change, so confirm them with the provider before you pay.
