N/A ridge preservation-xenograft-Bio-Oss-PRF. Intervention 1: Control group: Bio-Oss group: CBCT radiography is taken. after optimum local anesthesia, tooth is extracted using less traumatic approach and minimum reflection of the flap. Bio-Oss is prepared with conventional method and is applied to overfill the socket. Bio-Gide membrane is used to cover the socket completely. flap is sutured with 4-0 vicryl and figure of 8 technique. 3 month later CBCT radiography is taken again, Biopsy is harvested before the implant placement. Intervention 2: Intervention group: Bio-Oss + A-PRF group: CBCT radiography is taken. after optimum local anesthesia, tooth is extracted using less traumatic approach and minimum reflection of the flap. Bio-Oss is mixed with A-PRF (by centrifuging the patient's blood) and is applied to overfill the socket. Bio-Gide membrane is used to cover the socket completely. flap is sutured with 4-0 vicryl and figure of 8 technique. 3 month later CBCT radiography is taken again, Biopsy is harvested before the implant placement.
