If I Have a Impacted Tooth Can Invisalign Be Used to Make the Space Bigger for an Implant?

It depends on the space and the angulation of the roots of your teeth.  in order for the surgeon to place your implant there should be enough space for the tooth above the bone and inside the bone, since the implant is placed in between the roots of the 2 adjacent  teeth.  Its usually hard to control root movement with invislaign.  Your dentist/orthodontist will give you a better  answer based on your case.

If you have an impacted tooth with a baby tooth still present it is probably a cuspid. (check with your orothodontist on that).  If it is an impacted cuspid it would probably be a lot more efficient and a much better long term result to put on some braces, clear or tooth colored if you like that better, open up the space, get the baby tooth out and place an attachment on the impacted tooth and bring it into its proper place.  If you do that you won't have to cover the cost of the implant, the cost of the crown and it will probably be a lot better looking tooth than the implant will be. It will also be  without the potential problems of gum recession around the metal implant that can look quite bad when the metal gets exposed later.  In order to know how difficult it will be to get the cuspid brought into position, you should have a cone beam CT scan taken.   Be sure to get an orthodontic specialist who can read and evaluate the information on the CT scan to show you exactly where the impacted tooth is and exactly what it will take to get it ito its proper position.  You need to find out exactly how far out of position the tooth is before you embark on the whole process.    You will be much better off if you can keep your own real tooth instead of having an implant.
