If the tooth has already been removed and provided there is adequate bone present, it can traditionally take 3-4 months from the time of implant placement to restoration with a permanent crown. However, recent advances in implant dentistry now make it possible in some circumstances to remove a tooth, place an implant and restore it with a provisional crown on the same day, this is known as immediate implant placement.
The total treatment time from tooth extraction to replacement with a permanent porcelain crown varies depending on the clinical situation. Your dentist will provide you with an expected treatment time and if you are suitable for immediate implant placement at your initial consultation.
