Your oral surgeon places the abutment, which is an extension of the implant metal post. (In some cases, when the implant is very stable, this can be done at the same time that the implant is placed.)
After the soft tissue heals, your dentist will make molds of your teeth and jawbone and later place the final tooth or teeth.
The entire process can take many months from start to finish. Much of that time is devoted to healing and waiting for the growth of new bone in your jaw.
