      <study_design>Randomization: Randomized, Blinding: Double blinded, Placebo: Not used, Assignment: Parallel, Purpose: Supportive, Randomization description: Random sampling will be done among the patients referred to the Faculty of Dentistry in Tabriz who are eligible for the study. The randomization method is simple and its unit is individual. Our tool for randomizing a table of random numbers. Based on this, the type of treatment is marked with codes A (intervention) and B (control) and placed inside the sealed envelopes. The envelopes are placed in a bag and mixed. Then it is randomly selected from the bag and treatment is given to the patient by observing the code. Patients do not know the type of intervention on each jaw side, Blinding description: This study is double-blind so the patients do not know about the type of intervention on each side of the jaw. The evaluating researcher will not know about the type of intervention performed. Patients know the type of material but do not know which side of the jaw will be used.</study_design>

      <hc_freetext>Dental implant.</hc_freetext>
      <i_freetext>Intervention 1: Intervention group: In order to obtain concentrated growth factor, on the day of surgery, a 9 cc venous blood sample was taken from the patients and this sample will be centrifuged (Medifuge MF200; Silfradent®Srl, S. Sofia (FC), Italy) at a speed of 2400 to 2700 rpm. After tooth extraction, using a probe, the maximum socket diameter will be measured in both mesiodistal and palatal/lingual vestibule dimensions at the crestal level. One of the sockets will be filled with CGF and to preserve the biomaterial, a membrane prepared from CGF and a horizontal figure of 8 suture will be used on the socket. The pain level of the patients up to 7 days after the operation by visual analogue scale and the quality of the soft tissue of the area. Surgery (tissue color and consistency, pus discharge, bleeding) will be evaluated 7 days after extraction, through a modified version of Landry, Turnbull and Howley's Healing Index (HI). Finally, after 2 months, the patients will return and mesiodistal dimensions and vestibule palatal/lingual socket measured again from the dental socket will be sampled for histological evaluation. After fixation and decalcification, the samples will be stained with hematoxylin and eosin (H&amp;E) and histomorphological factors (percentage of remaining scaffold, bone and connective tissue) will be evaluated. At the same time, implants will be placed in place and Guided Bone Regeneration will be performed if needed. Intervention 2: Control group: After tooth extraction, maximum  socket diameter will be measured using a probe in both mesiodistal and palatal/lingual vestibule dimensions at the crestal level. The control socket will be restored automatically without any intervention. The pain level of patients up to 7 days after the operation by visual analogue scale and the quality of the soft tissue of the surgical area (tissue color and consistency, pus secretion, bleeding) 7 days after the extraction, through a modified version of Landry, Turnbull and Howley's Healing Index (HI) will be evaluated. Finally, after 2 months, the patients will return and mesiodistal dimensions and vestibule palatal/lingual socket measured again from the dental socket will be sampled for histological evaluation. After fixation and decalcification, the samples will be stained with hematoxylin and eosin (H&amp;E) and histomorphological factors (percentage of remaining scaffold, bone and connective tissue) will be evaluated. At the same time, implants will be placed in place and Guided Bone Regeneration will be performed if needed.</i_freetext>
