ABSTRACT


Aim: Clinical And Radiographic Studies Were Used To Examine The Amount Of Horizontal Bone Gain 4 Months Following Alveolar Ridge Augmentation Using IPRF Nano-micro Sticky Bone With Perforated Collagen Membrane Against Occlusive Barrier Membrane.Patients And Methods: The Study Represents An Observational Analytic Randomized Case-controlled Study Of Twenty Patients Having Horizontal Alveolar Ridge Defect, Where Augementation Was Done For Them By Using IPRF Nano-micro Sticky Bone. Patients Were Divided Randomly Into Two Groups. Randomization Was Performed By Using Coin Flipmethod. Each Group Included Ten Patients, (Group 1) Had Horizontal Alveolar Ridge Augmentation Using IPRF Nano- Micro Sticky Bone With Perforated Collagen Membrane, While (Group 2) Had A Horizontal Alveolar Ridge Augmentation Using IPRF Nano-micro Sticky Bone With Occlusive Collagen Membrane. A Radiographic Assessment Using CBCT, As Well As A Clinical Assessment, Was Done For Both Groups After A Follow Up Period Of 4 Months. The Study Was Approved By The Ethics And Research Committee Of The Faculty Of Dentistry, Ain Shams University.

Results: A Slight Bone Reduction In The Two Studied Groups Was Observed After The 4 Months Follow Up, In Comparison To Post-operative Readings. Those Differences Were Found To Be Statistically Highly Significant The Mean Percent Of Bone Reduction For Perforated Membrane Was Lower Than That For Non-perforated Membrane Group During Follow Up. That Difference Was Also Found To Be Statistically Significant.Conclusion: Both Perforated Collagen Membrane And Occlusive Barrier Membrane Showed Decease In The Bone Width And Reduction In Bone Gain After 4 Months Of Follow Up. When Comparing Both Membranes The Percentage Of Post-operative Bone Reduction In Perforated Collagen Membrane Is Lower Than That Of Occlusive Barrier Membrane.
