Implant Placement in Mandibular Molar Xenograft Versus PRF

Immediate Implant Placement With Deproteinized Bovine Bone (Tutogen) Versus Placement of Platelet-rich Fibrin as a Space Filling Material in Mandibular Molars. Randomized Clinical Trial.

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.

Inclusion Criteria:

1. Patients with non-restorable mandibular molars

2. Both sexes
