How much is the precise cost for just Invisalign impressions?

Every clinic has its own way of working and fees, so can't comment on whether you're being overcharged or not. At our practice, we normally don't charge separately for impressions if the patient is sure he/she wants to get Invisalign, and the cost is included in the total price. In case the patient is not sure, we charge $100 for Impressions, Photographs and X-rays.
Hope this helps.
Warm Regards.

charges are completely depends on doctor. so its difficult to answer this question , but in my practice i charge $3100 for invisalign full [complex cases] including all [records + invisalign + refinments + retainers].

HI, thanks for sending your question. Every office had different set fees and procedures, therefore its difficult to state that if you are being overcharges. I recommend that you review your treatment contract.  Its important to mention that based on what you described it appears to be reasonable charges for the services. We don't charge our patients for our records, it is a part of our entire treatment process. We also take scans, which eliminates the need to have to take impressions, and it is much easier for our patients. All the best.
