    Summary
    Purpose: The purpose of this study was to compare bone healing of experimental osteotomies applying either piezosurgery or two different oscillating saw blades in a rabbit model. Methods: The 16 rabbits were randomly assigned into four groups to comply with observation periods of one, two, three and fiveweeks. In all animals, four osteotomy lines were performed on the left and right nasal bone using a conventional saw blade, a novel saw blade and piezosurgery. Results: All three osteotomy techniques revealed an advanced gap healing starting after oneweek. The most pronounced new bone formation took place between two and threeweeks, whereby piezoelectric surgery revealed a tendency to faster bone formation and remodelling. Yet, there were no significant differences between the three modalities. Conclusions: The use of a novel as well as the piezoelectric bone-cutting instrument revealed advanced bone healing with a favourable surgical performance compared to a traditional saw
