Brief Summary:
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.

Condition or disease Intervention/treatment Phase
Edentulous Alveolar Ridge Procedure: extraction,implant placement,PRF Procedure: Exctraction,Implant placement,Bone graft Not Applicable

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 20 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single (Participant)
Primary Purpose: Treatment
Official Title: 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.
Actual Study Start Date : July 2016
Estimated Primary Completion Date : July 2017
Estimated Study Completion Date : July 2017

Arm Intervention/treatment
Experimental: extraction,implant placement,PRF
Extraction of Mandibular first molar and Implant placement followed by Placement of placement of Platelet rich fibrin as space filling material
Procedure: extraction,implant placement,PRF
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 Then a blood sample is withdrawn from patient and placed in the centrifuge.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

Active Comparator: Exctraction,Implant placement,Bone graft
Extraction of mandibular first molar followed by implant placement and xenogenic bone graft as space filling material
Procedure: Exctraction,Implant placement,Bone graft
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

Primary Outcome Measures :
  1. Patient satisfaction [ Time Frame: 1 week post operative ]
    evaluation of postoperative complications regarding pain and oedema

Secondary Outcome Measures :
  1. implant stability [ 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 ]
    measurement of implant stability using osstell device

  2. amount of bone gained or lost around the implants [ Time Frame: 6 months postoperative ]
    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
