ABSTRACT


Aim: The Aim Of This Study Was To Introduce And Evaluate A New Technique For Socket Preservation Involving Internal Expansion Of The Buccal Plate Of The Extraction Socket Using Internal Flaplesscorticotomy And Bone Grafting The Extraction Socket With Application Of Bioresorbable Membrane In Comparison With The Conventional Guided Bone Regeneration Technique For Socket Preservation.Methods: 22 Patients With 22 Non Restorable Teeth Requiring Atraumatic Tooth Extraction In The Maxillary Anterior Or Premolar Area Ranging To The Second Premolar With An Intact Buccal Plate Of Bone And No Periapical Pathosis. They Were Randomized Into 2 Groups, 11 Patients In The Test Group In Which Extraction Socket Preservation Using Buccal Plate Expansion Technique Is Performed , And 11 Patients In The Control Group In Which Socket Preservation With Guided Bone Regeneration Technique Using Natural Bovine Bone Mineral And Collagen Bio- Resorbable Membrane Was Performed. Post-operative Pain And Swelling Were Recorded.

Results: Higher Mean And Median Post-operative Pain Were Recorded In The Test Group 2.29 (?2.21) While In The Control Group 0.94 (?1.36). The Difference Between Groups Was Statistically Significant(p=0.00). The Same Median Value Of Post-operative Swelling Was Recorded In Both Groups, With A Higher Mean Value Recorded In The Test Group 1.62 (?0.73) While The Control Group 1.29(?0.56), The Difference Between Groups Was Statistically Significant (p=0.001)Conclusion: Higher Post-operative Pain And Swelling Was Observed With The Buccal Plate Expansion Technique For Alveolar Socket Preservation In Comparison To The Standard Method.
