With a full arch restoration such as the widely advertised “All-on-4” solution, once the teeth are removed and the implants placed, an immediate temporary restoration is placed. This is sometimes advertised as “teeth in a day” and specifically refers to that process of replacing all of teeth in either the upper or lower arch with that technique. In these cases the patient will indeed get immediately restored.
When dealing with a single tooth or less than all the teeth, most surgeons will want to defer tooth/crown placement to enhance healing and ensure implant success. It some cases, some anterior (front) implants may have a temporary tooth placed immediately. This is a process to discuss with your surgeon to understand more fully.
