Brief summary

study target is assessment of the accuracy of linear measurement obtained from CBCT images on 3D volumetric rendering and multiplanar slices with different voxel sizes

Detailed description

The real linear measurement will be measured in millimeter (mm) on the mandibles using digital caliper in the chosen areas. CBCT images will be viewed by OnDemand3D™ viewer software and linear measurements using 2D ruler on multiplanar slices and 3D ruler on 3D volumetric rendering to assess for the dimension in the chosen areas.
