"Osseodensification Efficacy on Molar Septum Expansion in Immediate Molar Implant Placement

The ideal positioning of immediate implants in molar extraction sockets often requires the osteotomy to be in the interradicular septum, which can be challenging in some cases, with traditional site preparation techniques. Also, the alveolar ridge undergoes various remodeling processes following tooth extraction, resulting in hard and soft tissue loss which complicates prosthodontic rehabilitation. Immediate implant placement help preserve the alveolar ridge dimensions and buccal ridge contour. While osseodensification has shown promise in enhancing primary stability and bone microarchitecture, its clinical and microstructural effects in molar extraction sockets remain underexplored. Although there is ample documentation of information on the temperature that is generated during preparation of implant sites, there are no studies available in the literature comparing conventional drilling and osseodensification techniques; therefore, the present investigation was aimed at analyzing the efficacy of osseodensification compared to conventional drilling in terms of bone dimensions preservation , changes in bone architecture during implant site preparation and heat generation to define which technique can be safely applied to achieve the necessary implant primary stability without damaging the surrounding bone. Aim of the study: Is to compare the molar septum dimensions using osseodensification expansion versus the conventional drilling protocol and to assess the role of jumping gap grafting in preservation of the alveolar ridge dimensions and buccal ridge contour in addition to Evaluation of the effect of osseodensification on the bony micro-architecture and heat generation
