Purpose: The purpose of this study was to evaluate and to compare the bone-cutting performance and intraosseous temperature development of three modern ultrasonic devices for bone surgery (UDBS).

Materials and methods: The following UDBS and associated cutting tips (straight bone saws) were used in this study: (1) Piezosurgery II professional, tip OT 7 (Mectron); (2) Piezotome, tip BS 1 (Acteon); and (3) SurgySonic, tip ES007 (American Dental Systems/Gunther Jerney). In the experimental setup UDBS, handpieces were immobilized, and bone specimens from the middiaphysis of a bovine femur were moved in a longitudinal direction under the cutting tip to a standardized depth of 3.0 mm. Intraosseous temperature development was measured using a glass-fiber isolated thermocouple. The cutting performance was defined by the time required to reach the cutting depth of 3.0 mm. Statistical analysis was performed u...
