This all depends on the number of implanted teeth. Same day dental implants can typically be done in a single procedure, taking an entire day, which includes (step 1) extraction (step 2) CT scan (step 3) placement of the implant and (step 4) the healing cap.
For multiple implants, a lot of preparation goes into planning, and you’ll likely have to see your doctor 4 times (visit 1) for consultation and surgery (visit 2) to place the healing cap (visit 3) impression for the crown, and (visit 4) is placing the crown.
