Invisalign with implants (stage one). Will I need to wait until Invisalign is completed in order to complete the implants?

Hey, I've had three dental implants (three molars at the bottom) placed a few weeks ago and my dentist informed me that I can start with invisalign soon, but my question is how will it work since I don't have crowns on them? She will place the abutment on my next visit and take my molds. I read on here that you recommend invisalign be done before a crown is placed, but my question is will I need to wait till invisalign is completed in order to complete the implants?
