title: Morphological characteristics of osteotomies using different piezosurgical devices. A scanning electron microscopic evaluation.
abstract: OBJECTIVE
  The objective of this study was to compare morphological characteristics of osteotomies performed by 6 Piezosurgical devices.
  
  
  METHODS
  The 6 Piezosurgical units were: (a) Piezotom, (b) SurgySonic, (c) Piezon Master Surgery, (d) VarioSurg, (e) Surgybone, and (f) Piezosurgery 3. Osteotomies on 9 freshly slaughtered cattle ribs (2 cuts by each unit, per rib) from the cortical (first cut at 5 mm) to the cancellous (second cut at 3 mm) bone layer were performed. The osteotomy margins were compared using scanning electron microscopy analysis. The cutting areas, osteotomy bottoms, and osteotomy margins were analyzed morphologically. Statistical evaluation of the 2 cuts regarding the design of the tips (a-d: tapered tool shanks, f: parallel tool shank) was performed by an unpaired t test.
  
  
  RESULTS
  Morphological characteristics were different for each Piezosurgical unit and each examined area. A significant difference (P = 0.0209) of the upper width of the first cut between tapered and parallel tips was shown.
  
  
  CONCLUSIONS
  The morphological characteristics of the produced Piezosurgical osteotomies vary and depend on the Piezosurgical unit and tip.
