Patient Outcomes of Staged Ridge-splitting Using Piezo-electric Surgery in Atrophic Posterior Mandible

Unlike the conventional ridge-splitting where bone grafting is done in the same visit after ridge splitting, modified ridge splitting involves splitting the ridge only at the first visit, then bone grafting is done either alone afterwards in the second visit (Modified 3-Staged Ridge-Splitting Group) and dental implants will be placed in the third visit, or, as in the Modified 2-Staged Ridge-Splitting Group, bone grafting and dental implants placement will be done in the second visit.
