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.

| Exctraction,Implant placement,Bone graft | Procedure | 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 |
|
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 |
| 6 months postoperative |
