Full Invisalign vs Express, my clincheck is only 11 trays?

if it is only 11 trays then best option is invisalign express. if u need few more additional trays then also it is cost effective option.

Seems like express would be a good option for  you.  I would suggest looking at your current Clin Check and see how your teeth appear after aligner #10.  There should be only minor movement from aligned #11, and you could opt for refinement aligners after Express treatment to get you there.  This would be much less expensive than Invisalign Full.  I always felt Invisalign should offer an option between Express and Full for your type of case.  On these cases, I always recommend Express to my patients.
