Immediate Implant Placement With Platlet Rich Fibrin as Space Filling Material Versus the Use of Deprotienized Bovine Bone (Tutogen) in Maxillary Premolars.

Immediate Implant Placement With Platlet Rich Fibrin as Space Filling Material Versus the Use of Deprotienized Bovine Bone (Tutogen) in Maxillary Premolars. A Randomized Controlled Clinical Trial

20 subjects suffering from non restorable maxillary premolar teeth will be randomly devided into two groups. the selected teeth will be extracted and immeiate implants will be placed in all subjects. the first group will recieve deprotienized bovine bone (tutogen) to fill the buccal space between the implant and the bone, the second group will recieve platlet rich fibrin to fill the buccal space between the implant and the bone

Inclusion Criteria:

• non restorable maxillary premolars non smoker free from any systemic disease or medication that could impair normal bone healing

Exclusion Criteria:

• any systemic disease that could affect bone healing patient with lesion related to the surgical site
