Findings from Sacred Heart Catholic University Has Provided New Data on Bone Research (Computer-Aided Design Evaluation of Harvestable Mandibular Bone Volume: A Clinical and Tomographic Human Study)

By a News Reporter-Staff News Editor at Health & Medicine Week -- Current study results on Bone Research have been published. According to news reporting originating from Rome, Italy, by NewsRx correspondents, research stated, "To evaluate and compare the volume of bone graft material that can be safely harvested from the mandibular symphysis and rami using a computer-aided design (CAD) software program. Preoperative computerized tomography scans from 40 patients undergoing bone augmentation procedures were analyzed."

Our news editors obtained a quote from the research from Sacred Heart Catholic University, "Symphysis and rami cross sections were mapped using a CAD software program (AutoCAD , Autodesk, Inc., San Rafael, CA, USA) to evaluate the bone volume that can be safely harvested. CAD calculations were contrasted to intrasurgical measurements in a subgroup of 20 individuals. CAD calculations yielded a safe harvestable osseous volume of 1.44cm3 +/- 0.49 for the symphysis and 0.82cm3 +/- 0.21 for each ramus (p <.0001, confidence interval [CI] 95%: 0.47-0.78). These measurements were significantly lower (p <.0001) than the bone volumes harvested intrasurgically for both symphysis and ramus, respectively (2.40cm3 +/- 0.50 vs. 2.65cm3 +/- 0.45). CAD calculations of harvestable symphysis and ramus bone translated into an average of 2.40cm3 +/- 0.50 (range: 1.80-3.10cm3) and 2.65cm3 +/- 0.45 (range: 1.90-3.50) of particulate bone graft intrasurgically, respectively. Ramus cortical was significantly thicker than the symphysis cortical, 2.9 +/- 0.4mm versus 2.19mm +/- 0.4mm (p <.0001, CI 95%: 0.45-1.03). The symphysis and rami are good harvesting sources to obtain dense corticocancellous bone. The significant volumetric CAD differences between the symphysis and ramus seem to balance out intrasurgically and may be due to the greater cortical bone volume at the ramus area. It is plausible to harvest an average of 7.70cm3 from the symphysis and rami alone."

According to the news editors, the research concluded: "The use of a CAD software program can enhance surgical treatment planning prior to bone transplantation."
