What is the difference between invisalign and clear-step braces?

Q. I know this site is dedicated to invisalign but would you please be able to tell me what the actual difference is between invisalign and clear step braces? Are they not just along the same lines.
A. NO, THEY ARE NOT.
clearstep does not involve any scanning/ rapid prototyping/ 3D technology.
What you get are technicians creating plaster models, cutting the stone teeth, resetting them to another position and then creating gum shields to try to move the teeth. Impressions are done ever 3 months as this technique is not accurate and only useful for easy cases.
Invisalign is created by Align Technology, a 4Bllion dollar company, which involves the above processes that Clearstep, and other copy companies are not doing.
If CS was that good then I would have switched 5 years ago. Invisalign works in my hands.
