ABSTRACT
Objective: To Assess The Effect Of Posterior Mandibular Ridge Augmentation Using Mineralized Plasmatic Matrix Versus Autogenous Bone Graft On Implant Body Stability: A Randomized Clinical Trial Comparative Study.

Materials and Methods: Twenty Implants Were Placed In Eight Patients With Defective Edentulous Posterior Mandibular Ridge. After Diagnosis Of Each Case Clinically And Radiographically, Patients Were Randomly Assigned Into Two Equal Groups Of 4 Patients Each. After Implant Placement, The Ridges Assigned To The Study Group Received MPM ? Prepared By Centrifugation Of Patient?s Blood- Mixed With Autogenous Bone Graft; While Ridges In The Control Group Received The Gold Standard Of Particulate Aurogenous Bone Graft With High-density PTFE Membrane. Implant Stability Was Assessed In ISQ Unit By Osstell, And Vertical Bone Height Was Assessed By CBCT At 0 And 6 Months. All Demographic Data And ISQ Scores And CBCT Measurements Were Collected And Statistically Analyzed.

Results: Results Showed That, There Was A Statistically Significant Increase In Implant Stability, And Vertical Bone Height After 6 Months In Both Groups (P < 0.05). The Mean Value Of ISQ Scores, Buccal And Lingual Vertical Bone Height In Was Not Statistical Different Between Both Groups Neither At 0 Nor At 6 Months (P > 0.05). The Mean Osstell Gain, Buccal, And Lingual Bone Height In The Study Group Was Significantly Higher Than That In The Control Group (P < 0.05). Conclusion: The Results Suggest That Both Techniques Can Be Used To Improve Implant Stability. The Use Of MPM In Osseous Regeneration And Implant Therapy Have A Positive Impact In The Outcome Of The Grafting Surgery. It Eases And Enhances The Delivery And Homogenization Of The Grafting Materials.
