N/A Immediate implants and delayed implants. Intervention 1: Intervention group: Immediate technique: The tooth was a-traumatically extracted and washed into saline solution and curettage. The drilling was done in the right position and the area that implant was inserted. If the torque was above N / CM 35 and had a good initial stability, after 24 hours after the surgery, the interim crown was referred to the prosthetic and placed after 4 to 3 months of permanent crown surgery. At this stage, the papillary index, the bleeding index, and the probing pocket depths were measured, and the PA radiography was used to evaluate the radiolucency and also to determine the rate of bone resorption. The patient then returned 8 months to re-measure the indicators. Intervention 2: Intervention group: Delayed technique: In this technique, toothless cases that were candidates for the implant were selected and after anesthetizing and incision, mucousal flap was performed and exposed bone and implants were implanted. After 3 months, the patient was referred and the crown was placed. In this stage, the above indicators were measured and also were measured 8 months later.
