Details and patient eligibility

About

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

Full 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.

Enrollment: 9 estimated patients

Sex: All

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• Selection of the human dry mandibles will be independent of age, gender and ethnicity.
• They should be intact, free from any bone defects, fractures, pathology.
• Dentate state of the mandibles is not an element in selection criteria; either dentulous or edentulous mandibles are acceptable
