“…Burs/drills vs piezotomes: With moderate to strong evidence (EL: 1,3; Table 1) and consecutive substantial clinical impact piezotomes seem to provide an improved bonehealing, proved on molecular-biologic, micromorphologic and histologic level in vivo, when compared to rotary instruments. Furthermore, a superior soft-tissue-preservation is reported compared to drills and burs [70][71][72][73][74][75][76][77][78][79][80][81][82][83][84][85][86].…”

Background: New tools for bone-cutting were introduced to oral and maxillofacial surgery in the last decade, such as lasers and piezotomes. Purpose: to evaluate most recent evidence, when surgical procedures performed with drills or burs are compared with laser-and/or piezotome-surgical procedures in experimental and clinical studies and to assess possible advantages of their use in daily practice. Methods: a systematic search of various medical databases with specifi c keywords was performed, excluding studies published before 2006 for their possible invalidity by technological progress. Systematic reviews were assigned to Group 1, experimental studies ex vivo to Group 2, in vivo to Group 3 and clinical studies to Group 4. All studies in each of the groups 2-4 were appraised regarding their evidence, starting with a value of 0 for no evidence of advantages of lasers and/or piezotomes compared to rotary instruments, 1 for moderate evidence with verifi ed clinical impact and 2 for strong evidence and signifi cant clinical impact and statistically processed for their Evidence Value (EV) in each group and their Overall mean Evidence Value (OmEV). Results: 129 studies were fi nally included for evaluation. Two systematic reviews concluded lack of evidence for lasers to be advantageous over burs/drills. Nine reviews for piezotomes reveal strong evidence piezotome-surgery to signifi cantly reduce morbidity and to enhance soft-tissue preservation. Comparative experimental and clinical studies of burs/drills vs lasers revealed a low EV in Group 2 (EV:0,8), Group 3 (EV:0,5) and Group 4 (EV:0,5) with an OmEV of 0,6. Comparative studies burs/drills vs piezotomes resulted in a signifi cant EV in all groups (

Background:Autogenous bone graft harvesting from the iliac crest is associated with donor site morbidity. The aim of this report is to describe the use of piezosurgery as an attempt at morbidity reduction.Materials and Methods:A piezosurgical handpiece and its selection of tips can easily be accommodated in an iliac crest wound to osteotomize and allow the harvest and delivery of autogenous bone grafts.Results:Corticocancellous blocks or cancellous strips of autogenous bone can be readily harvested using a piezosurgical technique at the anterior iliac crest.Conclusion:Piezosurgery avoids some of the traumatic aspects of harvesting bone associated with the use of conventional rotary instruments or saws.

Ultrasonic osteotomy devices (UODs) have many clinical benefits; for example, they cause little damage to adjacent tissues in oral surgery. However, few reports have focused on bone healing with UODs. This study aimed to compare bone healing after osteotomy with UODs versus rotary osteotomy devices (RODs) in a rat calvarial defect model. Calvarial bone defects were made with a UOD on the right side and an ROD on the left side. Micro-CT analysis revealed that the bone volume was greater with a UOD than with an ROD at 2-3 weeks. In HE-stained sections and micro-CT images, the bone wound gap was closed earlier on the UOD side than on the ROD side. Bone thickness, the quantity of newly formed bone, and the number of osteocytes were greater on the UOD side than on the ROD side. Scanning electron microscopy (SEM) showed that UOD cuts had smoother surfaces than ROD cuts. Osteoblast-like cells harvested from bone chips cut by the UOD had greater proliferative activity than those harvested from ROD-cut bone chips. The use of a UOD may assist bone regeneration, presumably because of osteoblast activation by ultrasonic microvibration and UODs cause less damage to the bone than RODs.
