Clear aligner systems for dental practices

Clear aligners are removable, transparent trays for orthodontic treatment that the dentist or orthodontist orders for each patient. This subguide belongs to dental suppliers and compares aligner systems that a public source shows US dental practices can order, on the same criteria: regulatory status, requirements for becoming a provider, treatment planning, scanners and impressions, packages and retainers, and training and support in the US.

As of October 18, 2026, the overview covers five systems: Angel Aligner, ClearCorrect, Invisalign, Spark and SureSmile. None of them publishes a price per case for the practice: for Invisalign the manufacturer says pricing is quoted (on request¹), and the only published amount is the provider certification (fee $500 «Start offering Invisalign® treatment with certification for just $500» (footnote 6 not read). Promotion available through December 31, 2026 (footnote on the source page). sales tax not stated (payment period not stated)²). For the other four systems we found no public price when we searched on October 18, 2026, so get the price per case in writing before you choose.

For each system the manufacturer, the system name and the US seller are shown separately. The guide compares what your practice buys; the fees practices charge patients are not included. The guide does not assess clinical performance: which cases suit aligners, treatment time and outcomes are not compared, and nothing here says one system gives better results than another.
