Clinical Trial 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

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.
