The shortest most predictable esthetic correction for you would be utilizing a short timne frame aligner system such as invisalign express or simply 5 by AOA labs

very cost effective

keep smileing

The best answer to your question is to see a local orthodontist that can evaluate your bite and smile in person

keep smiling

It appears that the orthodontist is delivering more aligners in 6 weeks and the attachments were removed in order to scan your teeth( not the attachments)

Without the attachments trays may not fit as well , but this should be a temporary issue until the new aligners arrive

Sometimes if you pinch the cheek side and the tongue side of the aligner together in molar and premolar area of the aligner  prior to placing the aligner in your mouth this will enhance the fit

Good Luck

A suggestion( best if you contact your orthodontist if they still are ill fitting after 2 weeks)  use a cotton roll between the trays to bite the trays into place working from the back right around to the back left

The trays should be fitting your teeth much better at the end of the two week cycle as the aligners are moving your teeth to where they are to be in two weeks ...not where they are now

hope that helps

A consideration for you case when done correctly would be to discuss a canine substitution where the canines are moved into the lateral position and reshaped to look like a lateral incisor.

If done well no one can tell the difference and it avoids 2 implants that are difficult to make look natural in the aesthetic zone of your smile .

Discuss this with an orthodontist
