In order to get an overdenture, you may first have to get any remaining tooth roots extracted from the arch that you want the denture to be placed on. This means a healing period, which can last up to 3-4 months. Everybody heals differently, and your waiting period may be shorter or longer. If your jaw has become too brittle or thin to be able to house an implant, you may need a bone graft. That may incur an additional few months of healing time (up to 6, depending), before the implantation process can begin.
After any necessary removals have been done, your impression will be taken and the technical work of making your overdentures will begin. During this session, your jaw will be implanted with the implants that will stabilize your denture. It takes a couple of weeks to get the plastic to be the right width and shape; after that it is ready to be inserted and connected with your implants. The whole procedure can be done in just three trips to the dentist. The process is the same with the cover denture as well, as the same implants hold the apparatus in place thus requiring the same healing time and the same dental work.
