ABSTRACT


Aim: Evaluation Of Socket Preservation Using Hydroxyapatite With Non-Resorbable Polytet-rafluoroethylenemembrane (Cytoplast Membrane) Versus Non-resorbable Polytetrafluoroethylenemembrane (Cytoplast Membrane) Only In Mandibular 1st Or 2nd Molar Sockets.Patients And Methods: The Present Study Was Conducted On 20 Cases Seeking Extraction Of Lower Firstor Second Molars. Patients Are Divided Into 2 Groups, Preservation Of The Extracted Sockets By Alloplastic Materials And Non-resorbable Membrane Was Done In Study Group And Preservation Of The Extracted Sockets By Non-resorbable Membrane Only Was Done In Control Group. All Extraction Sockets Were Assessed Postoperatively Immediately After Extraction, At 3 And 6 Months Intervals For Evaluation Of The Variation In The Bone Density At The Extraction Site Of Both Groups.

Results: The Bone Density Was Compared Between The Study And Control Groups At The Crestal, Middle And Apical Parts Of The Distal And Mesial Roots Immediate, At 3 Month And At 6 Month Post Operatively. Study Group Showed Mean Density Higher Than The Control Group And The Difference Was Statistically Significant For All IntervalsConclusion: The Bone Density In Sockets With Hydroxyapatite Is Higher Than The Sockets Which Are Covered With Cytoplast Membrane Only.
