Spark and Invisalign are clear aligner systems that move teeth with a series of removable, custom-made trays. They follow the same treatment steps and suit a similar range of cases. The differences are the manufacturer, the tray material, the planning software and the price: at North Sydney Dentistry, Spark is estimated at $500 less than Invisalign.

What they share
- Trays designed from an iTero scan of your teeth
- Worn most of the day and removed to eat, drink anything except plain water, and clean
- Tooth-coloured attachments on some teeth where needed
- A simulation of the planned movement to review first. It is a planning aid, not a guarantee
- Regular reviews, then retainers
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 TruGEN 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 system is better for everyone, and manufacturer comparisons are marketing claims rather than 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.
Is Spark cheaper than Invisalign?
Yes, at our practice. Our current price guide estimates Spark treatment at $3,700 to $8,490 and Invisalign at $4,200 to $8,990. Within each range, your fee depends on your treatment plan.

Risks
All aligner systems carry similar risks, including soreness with new trays, temporary speech changes, gum irritation, decay if hygiene slips, root shortening and movements that are not fully achieved. Read about treatment risks, recovery and alternatives.
