ABSTRACT
Purpose: This Preliminary Study Was To Evaluate Clinically And Radiographically The Volume Changes Of Alveolar Bone Grafting Guided By Resorb-x Membrane.
Patients And Methods: A Total Of Six Patients With Maxillary Anterior Localized Alveolar Ridge Defects � 3 Mm Were Selected. The Alveolar Ridges Were Reconstructed With Xenogeneic Bone Graft Particles Guided By Resorb-x Membrane. Linear Measurements And Volume Analysis Of The Changes In Alveolar Ridge Were Obtained Pre-operatively And Four Months Post-operative Using Cone Beam Computed Tomography (CBCT).
Results: Four Months Postoperatively, All Treated Defect Sites Exhibited Satisfactory Bone Formation. Clinical Results Showed Absence Of Any Foreign-body Reactions To Biodegradation Of Resorb-x Membrane And SonicPin Rx?. Measurements Made On CBCT, Four Months Postoperative Showed Statistically Significant Increase In Bone Width With Mean � SD: 2.37 � 1.77 Mm At 2 Mm, 2.46 � 1.56 Mm At 4 Mm, 2.36 � 1.05 Mm And 1.63 � 0.83 Mm At 8 Mm From Crest Of Alveolar Ridge Respectively. There Was Statistically Significant Increase In Bone Volume By 36.15% In The Area Of Newly Formed Bone. No Statistical Significant Changes Was Found In The Density Of Newly Formed Bone When Compared To The Density Of The Native Bone Four Months Post-operatively.
Conclusion: The Resorb-x Membrane Is An Improvement In The Search For A Mechanically Strong And Stiff As Well As A Biodegradable System. With Such Modifications In Properties, This Gives Resorb-x Membrane More Promising Chances To Be Used In Guided Bone Regeneration.
