Background: The study aimed to verify the accuracy of volumetric rendering software on cone beam computed tomography (CBCT) and multislice computed tomography (MSCT)-derived surface models. Materials and Methods: Gutta Purcha cone tips were fixed on 14 points at the facial surface of five dry mandibles. The mandibles were scanned twice with each scanner on three occasions. 26 distances were measured 10 times, using digital calipers. The surface models rendered by the software were linearly measured thrice and their means recorded. The data sets were subjected to vigorous statistical treatment using analysis of variance and Tukey test. Results: The caliper measurements, the CBCT and MSCT images were comparable, indicated by an F = 0.0003 and a Tukey T value (8.7), larger than the absolute difference between any two means. Thus, confirming the linear accuracy of the software. Conclusions: "SolidPlanner" volumetric rendering program yields a near 1-to-1 ratio with reality. The program enjoys linear accuracy, which remained submillimeter accurate, emphasizing the validity of the program as a measuring tool.
