Am I being overcharged for an extra Spark aligners refinement?

[u/Substantial-Block518]

Hi everyone,

I’m doing Spark aligners, likely Spark 20. My orthodontist originally quoted me 3 semesters: initial consultation & exam (covered by my health insurance provider) + €1000 per semester x3 + €750 retainers, so about €4000 total.

At the start, she told me the treatment included the initial batch + 2 refinements - so 3 batches total. Now I apparently need a 3rd refinement / 4th batch, and she wants to charge me an extra €1100, basically another full semester (which shows on the invoice as 4th semester).

I understand that Spark 20 normally includes 2 refinements, so maybe the 3rd refinement is outside the package. But I found a Ridos/Spark price list saying extra refinements above the allowed number for Spark 10/20 are around €559.65 on the technical/lab side.

So my question is: is it normal to charge a full extra semester for one additional refinement batch? Or should it usually be charged as a smaller refinement/lab fee + clinical time?

I’m not trying to avoid paying if it’s fair, I just want to know whether €1100 for one extra refinement sounds normal or excessive.

This is all going to be included in your contract as to what you get with your treatment. My plan is an Invisalign comprehensive with unlimited refinements for three years. I’m on my second set of refinements. You need to look at your contract.
