Ridge Expansion by Osseodensification Simultaneously With Implant Placement in Narrow Alveolar Ridges

Narrow alveolar ridges with a thickness equal or less than 5 mm requires bone augmentation procedures before or at the time of implant placement. (Anitua, Begoña, and Orive 2013) Several surgical techniques have been utilized for the reconstruction of deficient alveolar ridges such as block onlay graft augmentation, guided bone regeneration, distraction osteogenesis , ridge splitting and/or ridge expansion(McAllister and Haghighat 2007). A new bone drilling technique named Osseodensification facilitates horizontal ridge expansion. Studies are needed to validate the effectiveness of osseodensification as a lateral ridge augmentation procedure that aims at increasing the thickness of atrophic ridges, thus maintaining ridge integrity and allowing for implant placement with enhanced stability. The null hypothesis Proposes no difference in the bone width gain following the osseodensification drilling system compared to the ridge splitting technique with simultaneously placed implants in narrow alveolar ridges.
