20 recruited patients indicated for immediate implant placement in mandibular molar patients are divided into 2 groups each group contain 15 patients, one group assigned for placement of bovine bone after molar extraction and immediate implant placement, while the other group we use Platelet-rich fibrin as space filling material.

Surgical extraction of mandibular molar using periotome and forceps followed by implant placement in inter-septal bone. Then a blood sample is withdrawn from patient and placed in the centrifuge. Then Platelet-Rich fibrin is placed in the extraction socket as space filling material
Surgical extraction of mandibular molar using extraction forceps and periotome followed by implant placement in interseptal bone. De-proteinized bovine bone graft material is placed as space filling material
Patient satisfaction
evaluation of postoperative complications regarding pain and oedema
Time frame: 1 week post operative
implant stability
measurement of implant stability using osstell device
Time frame: will be measure intraopertively immediately after insertion of the implants and will be measure one more time 6 months after 1st operation at the time of exposure of implants
amount of bone gained or lost around the implants
two cone beam computed tomography (CBCT) will be taken for the patient, one immediate postoperative and the other 6 months after the operation then the height of bone gained or lost around the implants will be assessed by superimposing the same section in the two CBCTS
Time frame: 6 months postoperative
