Avoid implants with Invisalign while missing 2 lateral incisors? (Photo)

Your smile is very important, but your bite is even more important. Not having a proper bite can cause even more tooth and bone loss. Clear aligners may be a good alternative for you where you dont need to have fixed metal braces for a long period of time. 

Invisalign is >1mm thick tray and it apply very light force on teeth. but as u have bruxism so this tray will protect teeth by preventing further grinding. 

Thank you for posting your question.  Wearing an Invisalign aligner too long should not cause any problems.  Move on to the next aligner and let your dentist know.  Try to keep changing the aligners on time so that you can finish sooner rather then later.  Hope this helps.  Good Luck!

Yes, it is absolutely okay to change your aligner one night earlier as long as you have worn it enough hours for the time you had to and as long as you don't make it to a habit of changing others earlier every time.

It is my advice to upload pics so i can guide u better. by your description i feel issue is with occlusal plane. 

It is difficult to say anything without seeing your case. it is my request to upload pics so i can guide u better. if one can use standard debonding protocol with polishing thn no chances of any kind of damage to tooth surface.
