ABSTRACT
Background: The Aim Of The Present Study Was To Evaluate Clinically And Radiographically, The Alveolar Bone Status After Socket Preservation Using ?-tricalcium Phosphate With And Without IPRF Of Extracted Teeth Affected By Periodontitis Stage IV Grade C. .Methods: The Patients Were Randomly Assigned To Two Groups: Group I: (10 Patients) For Those Periodontal Surgical Procedures Of The Defects Were Filled With ? Tricalcium Phosphate Alone. Groups II: (10 Patients) Were Received Periodontal Surgical Procedures Where The Defect Was Filled With ? Tricalcium Phosphate Mixed With I-PRF. Cone Beam Computed Tomography Were Taken At Time Of Initial Examination And At 6 Months To Evaluate The Alveolar Bone Length, Width And Density.

Results: In The Present Study, Immediately, And 6 Months; There Was No Statistically Significant Difference Between Lengths In The Two Groups. ?-TCP /I-PRF Group Showed A Statistically Significant Less Percentage Of Change Than ?-TCP Group. Immediately, And 6 Months; There Was No Statistically Significant Difference Between Width In The Two Groups. ?-TCP /I-PRF Group Showed A Statistically Significant Less Percentage Of Change Than ?-TCP Group. Immediately, And 6 Months; There Was No Statistically Significant Difference Between Mean Density In The Two Groups. ?-TCP /I-PRF Group Showed A Statistically Significant Increase Bone Densitythan ?-TCP Group. Conclusion: Extraction Sockets Treated With I-PRF Combined With Alloplast Showed Least Reduction In Alveolar Ridge Width And Height At The End Of The Study Period, As Well As Greatest Increase In Bone Density Than The Other Studied Groups. Immediate Socket Augmentation Might Provide Advantages In The Management Of Extraction Sockets In Periodontally Compromised Teeth.
