Abstract
Aim: To verify whether the measurements obtained from three-dimensional cone beam computed tomographic (CBCT) imaging could replace those obtained from their real counterpart.

Methodology: Fifteen human dry mandibles were enrolled in the current study. Multiplanar reformatting 2dimentional(2D) and generated 3dimentional(3D) images were used to perform the linear measurements between the markers then 2D and 3D measurements were compared with the physical measurements taken with an electronic digital caliper.

Results: 2dimentional measurements had the least error which is highly significantly lower than 3dimentional measurements.

Conclusion: Linear measurements taken on multiplanar 2dimentional CBCT images are reliable and accurate for clinical diagnosis and treatment planning. Linear measurements on 3dimentional rendering images are reliable but with less accuracy than the 2 dimentional images.
