The effect of three autogenous bone harvesting methods on bone volume

Abstract: ABSTRACT Aim: To evaluate the relation between harvested bone and acquired bone for threedifferent methods used to harvest autogenous bone. Material and method: Bone was harvested from 15 sheep mandibles using threetechniques: bone block, bone scraper, and bone rongeur. Volume change wasdigitally measured with TRIOS 3Shape and 3D Slicer. Additionally, waterdisplacement was used for the bone blocks, and a syringe method was performedfor 0,5 and 2,0kg pressure on the particulated bone groups. Results: An initial volume loss of 24% was found when harvesting bone blocks.Harvesting particulated bone using a bone scraper or bone rongeur resulted in amean increase in the initial volume corresponding to a factor of 7,7 and 4,9respectively after 0,5kg pressure. Conclusion: Within the limitations of this study, a general trend for volume changefor the different techniques could be found. The bone block group decreased involume, whereas the particulated groups increased in bone volume. The bonescraper had a more considerable increase than the bone rongeur. Further research isneeded to calculate a precise and accurate factor of the volume change.
