Extraction of the tooth followed by Platelet rich fibrin placed in the socket covered bu platelet rich fibrin membrane for socket preservation.

Extraction of the tooth followed by using free gingival graft to cover the socket for socket preservation.

platelet rich fibrin will be prepared from patient's venous blood and inserted in the centrifuge at 2000 r.p.m. for 12 minutes Then, the Platelet rich fibrin plug will be placed in the socket after extraction for socket preservation covered by platelet rich fibrin membrane.

Optical scanning by optical scanner at baseline to the preoperative cast of the related area, then optical scanning to postoperative cast of the surgical area after 6 months. Then, superimposition between the two scans of the casts will be performed to measure the difference or change in the amount of soft tissue profile measured in millimeters between baseline and at 6 months

measured by Cone beam computed tomography (CBCT) taking the neighboring teeth as reference points, with superimposition between readings at baseline and at 6 months.

Superimposition will identify the difference or change in crestal bone level measured in millimeters between baseline and at 6 months.
