Ridge Atrophy is a common result of untreated extraction sites,Implants failure,untreated periodontal disease and long lasting use of removable prosthesis. The end result is inadequate ridge volume for placing implants.The new concept of “osseodensification” will be presented enabelling the clinician to preserve existing bone and enhance the outcome through a minimal invasive approach. Osseodensification is a novel, bio-mechanical, non-excavation osteotomy preparation method.
Unlike traditional bone drilling technologies, osseodensification does not excavate bone tissue. Rather, it preserves bone bulk, so bone tissue is simultaneously compacted and autografted in an outwardly expanding direction to form the osteotomy. It is accomplished by using proprietary densifying burs. When the densifying bur is rotated at high speed in a reversed, non-cutting direction with steady external irrigation (Densifying Mode), a dense compacted layer of bone tissue is formed along the walls and base of the osteotomy.
The presentation will show step by step procedure of this minimal invasive innovative technique for ridge expansion as well as sub crestal sinus augmentation with long term follow ups of both clinical and CBCT radiographs. It will highlight the benefits of this treatment modality compared to the existing techniques.
