“…Accuracy of linear Measurement accuracy on Galileos CBCT R Ganguly et al measurements on multislice spiral CT images (Toshiba Aquilion, Toshiba Medical System Corp., Tokyo, Hongo, Japan) in comparison with caliper measurements utilizing cadaver heads with intact soft tissues was determined by Cavalcanti and co-workers. 15 There was no apparent effect of the soft tissues on the accuracy of measurement as there was no statistically significant difference (P . 0.05) between imaging measurements and physical measurements obtained with calipers.…”

Objectives: The aim of this study was to determine the geometric accuracy of cone beam CT (CBCT)-based linear measurements of bone height obtained with the Galileos CBCT (Sirona Dental Systems Inc., Bensheim, Hessen, Germany) in the presence of soft tissues. Methods: Six embalmed cadaver heads were imaged with the Galileos CBCT unit subsequent to placement of radiopaque fiduciary markers over the buccal and lingual cortical plates. Electronic linear measurements of bone height were obtained using the Sirona software. Physical measurements were obtained with digital calipers at the same location. This distance was compared on all six specimens bilaterally to determine accuracy of the image measurements. Results: The findings showed no statistically significant difference between the imaging and physical measurements (P . 0.05) as determined by a paired sample t-test. The intraclass correlation was used to measure the intrarater reliability of repeated measures and there was no statistically significant difference between measurements performed at the same location (P . 0.05). Conclusions: The Galileos CBCT image-based linear measurement between anatomical structures within the mandible in the presence of soft tissues is sufficiently accurate for clinical use.

“…Three--dimensional (3D) reconstructed images from CBCT are more reliable and accurate than 2D radiography of craniofacial structures for diagnosis, and allow multiple imaging post-processing protocols for better and more effective treatment planning and evaluation [3,10]. Thus, many investigators chose 3D analysis to evaluate mandibular morphology, especially the latest development of CBCT which could help to provide better image resolution, shorten acquisition time, reduce the radiation dose, and lower costs [14].…”

“…2,[9][10][11] Three-dimensional reconstructed images from conebeam computed tomography (3D-CBCT) are more reliable and accurate than two-dimensional radiography of craniofacial structures for diagnosis, and allow multiple imaging post-processing protocols for better and more correct treatment planning and evaluation. 2,12,13 The aim of this study was to assess cone-beam computed tomography (CBCT) imaging using open source software, by analyzing which post-processing imaging protocol would be better for planning a procedure and for clearly identifying the existence of anatomical variations. Another aim was to test the reproducibility of 3D-CBCT for measuring anatomical landmarks, such as the MF and AMF, using open source software.…”

The purpose of this study was to evaluate which post-processing imaging protocol would be better to analyze the additional mental foramen (AMF) in preoperative planning with cone-beam computed tomography (CBCT) exams, and to test reproducibility of measurements, using open source software (OsiriX). The software was used to detect the cases of AMF from among 58 exams for dental implant planning in edentulous mandible areas-three cases were found. The case images were submitted to qualitative analysis using 2D orthogonal MPR, 3D-MPR and 3D volume rendering protocols by two oral and maxillofacial radiologists. Quantitative analysis used the 3D-MPR protocol; the closed polygon tool measured the mental foramen (MF) and the AMF areas; the length tool measured the distance between foramina. The measurements were performed independently by the examiners, at two different times. Intra-and interexaminer agreement was assessed using the intraclass correlation coefficient. The panoramic view did not show the MF and the AMF clearly. The AMF could be detected in the parasagittal view. 2D Orthogonal MPR was effective to observe the AMF in some cases. The 3D-MPR and 3D view protocols were the most effective to locate and analyze the AMF. In conclusion, a 3D view improves visualization when anatomical points are not clearly visible. 3D-MPR was considered a more effective post-processing imaging protocol to observe foramina relationships. The high reproducibility of measurements for anatomical MF variations was established using specific tools featured in open source software for CBCT. OsiriX is realistic and recommended for preoperative planning.
