ClinCheck is the software that your orthodontist uses to communicate your diagnosis and treatment plan to Align Technology so that they can manufacture your Invisalign aligners. If your orthodontist is using genuine Invisalign aligners and not an immitation, he definitely has a ClinCheck treatment plan for you that he had to submit. There is no way around it. While he cannot literally give you a copy of the software, he can generate a "video" of the plan using the software so you can see exactly what the aligners will do and in what sequence. Explain to your orthodontist that you would like to have him export a copy of your ClinCheck plan as a video so that you can "show it off." I'm sure he'll oblige!
