“…Draenert et al (24) stated that the OsiriX software is able to produce good-quality images of cancellous bones in their in vivo and in vitro study. After comparison among similar software, Yamauchi et al (25) considered OsiriX a highly functional DICOM viewer, which is an important tool for preoperative planning in spine surgery.…”

“…Chindasombatjareon reported the same in both CT and CBCT [ 27 ]. Another studies found an inverse correlation between the severity of metal artifact and applied voltage [ 28 , 29 ]. The majority of photons have medium level of energy and a small number of photons have maximum energy [ 5 , 12 , 30 ].…”

Background This study aims to evaluate the effects of the artifact removal algorithm on linear measurements of the buccal cortical plate by altering the voltage. Methods Ten titanium fixtures were inserted at the site of central, lateral, canine, premolars and molars of dry human mandibles. Vertical height of buccal plate was measured using a digital caliper as a gold standard. Mandibles were scanned with 54 and 58 kVp. Other parameters were constant. Images were reconstructed with none, low, medium and high artifact removal modes. Two Oromaxillofacial radiologists evaluated and measured the buccal plate height using Romexis software. Statistical package for the social sciences (SPSS) version 24 was used for data analysis. Results In medium and high modes, the difference between 54 and 58 kVp was significant (p < 0.001). No significance was noted by using low ARM (artifact removal mode) at the 54 kVp and 58 kVp. Conclusion Using artifact removal in low voltage decreases the accuracy of linear measurement and buccal crest visibility. By using high voltage, artifact removal would have no significant effect on accuracy of linear measurements.

“…Though multi-slice CT (MSCT) scan is an established method to assess the bone morphology in implant planning and is commonly regarded as the gold standard, it is associated with 40-60 times more radiation than CBCT systems that have been introduced more recently. In addition to lower dose of exposure, CBCT systems offer several other advantages over a medical CT, including shorter acquisition times, low cost, and adequate image quality of the mineralized tissues (17,18). Different studies have utilized various techniques using CBCT to approximate defects, but no study has directly compared these techniques.…”

Comparative assessment of 3D reconstruction technique and Cavalieri's principle in predicting the mandibular bone defect volumes PurposeThe objective of this study was to compare the accuracy of the Cavalieri's principle and 3D reconstruction in predicting the volume of a bony defect. Materials and MethodsDefects of the same approximate size were created on nine artificial mandibles. The actual volume of the defect on each mandible was measured by water displacement, and served as the control. Each mandible was then scanned using a CBCT and volume measurements were made for each defect using two techniques: Cavalieri's principle and 3D reconstruction. For each defect, the volume obtained by each of the two techniques was compared to the control volume using the analysis of variances (ANOVA) with p<0.05. ResultsANOVA between the control, 3D reconstruction and Cavalieri's principle groups showed no statistically significant differences (p=.058). When the control group was further analyzed by Dunnett's post-hoc test, the results from Cavalieri's principle were found to be statistically different than the control group (p=.035), whereas the results of 3D reconstruction technique did not reach the level of significance (p=.523). ConclusionCavalieri's principle significantly underestimates the actual control volume, and is less accurate than the 3D reconstruction technique. The 3D reconstruction method is a reliable technique in measuring volume of bony defects.
