Spark and Invisalign are both clear aligner systems. They use a series of removable, custom-made trays, follow the same treatment steps and suit a similar range of cases. The differences are the manufacturer, the tray material and the planning software. At our practice, Spark is estimated at $500 less than Invisalign.

How they are the same
- Trays are designed from an iTero scan of your teeth
- You wear them most of the day and remove them to eat, drink anything except plain water, and clean
- Tooth-coloured attachments may be bonded to some teeth
- You review a simulation of the planned movement first. It is a planning aid, not a guarantee
- Regular reviews, then retainers after treatment
How they differ
Manufacturer
Invisalign is made by Align Technology. Spark is made by Ormco, an orthodontic company that also makes brackets and wires.
Tray material
Ormco says Spark’s TruGEN material is designed for clarity and stain resistance, with polished, scalloped edges. Invisalign uses SmartTrack. Comfort is individual.
Planning software
Invisalign is planned in ClinCheck and Spark in Approver. Both show the planned movement step by step, and Ormco says Approver also supports cut-outs, hooks and bite ramps.
Which is better?
Neither is better for everyone. Manufacturer comparisons are marketing claims, not independent evidence. Diagnosis, planning and wearing the trays as prescribed usually matter more than the brand. We recommend a system after your assessment and explain why.
