I was originally told that the total in office visit for pictures and x-rays and impressions is approximately $500 and now because of a legal dispute, I believe they are punishing me by now trying to charge me a total of $1,196 for Invisalign Impressions ($800), Panoramic Film ($99), Cephalometric Film ($99), Oral/Facial Photographic Images Obtained Intraoral and Extraoral ($99), and Diagnostic Casts ($99). Does this equate to the average cost of these services? Did they overcharge me?
