Introduction: Subperiosteal preparation using a periosteal elevator leads to disturbances of local immunohistochemistry and periosteal histology due to a microtrauma. Usually soft-tissue damage can be considerably reduced by using piezoelectric technology. For this reason, the effects of a novel piezoelectric device on immunohistochemistry and periosteal histology were examined and compared to conventional preparation of the periosteum using a periosteal elevator.Material and methods: Lewis rats were randomly assigned to one of five groups (n=50). Subperiosteal preparation was performed using either a piezoelectric device or a periosteal elevator. Immunohistochemical and histological analyses were performed immediately after preparation as well as three and eight days postoperatively. A statistical analysis of the histological colouring was performed offline using analysis of variance (ANOVA) on ranks (p<0.05). Results: At all times, immunohistochemical and histological analysis demonstrated a significantly more homogenous tissue structure in the group of rats that underwent piezosurgery than in the group of rats that underwent treatment with a periosteal elevator.Conclusion: The use of a piezoelectric device for subperiosteal preparation is associated with more harmonious immunohistochemical and histological results for the periosteum than the use of a conventional periosteal elevator. As a result, piezoelectric devices can be expected to have a positive effect primarily on soft tissue, in particular of the periosteal as well as on surrounding tissues.
