Using the manual edition built in tool, first a brush of small size will be used to demarcate the outline of the condyle in the sagittal cuts. Then shading the demarcated condylar area with a brush of larger size in each slice. The outline of the condyle will be refined on all cuts. The software built in tool 'create surface' will be used to create the segmented 3D volume

Using the water shed built in tool, first a brush of small size will be used to demarcate the outline of the condyle by the 'background' option in all planes. Then using the 'foreground' option, a brush of larger size will be used to shade the condylar area. The software built in tool 'expand water shed' will be used to include the whole condyle. At last, 'create surface' option will be used to create the segmented 3D volume.

For linear measurements, actual physical measurements will be done on the dry mandibular condyles, using digital caliper, as mentioned before.

For volumetric measurements, water displacement technique will be used. The mandibular condyle will be immersed in a graduated beaker containing water till the level of the glued gutta percha. The volume of the displaced water will be measured and will represent the actual volume of the condyle

CBCT scanning

Linear measurements will be calculated in millimeters by Built-in measuring tool (ruler) in the software + digital caliper on the dry mandibles

For volumetric measurements, the volume of the segmented condyle, either by manual or semiautomatic segmentation technique, will be automatically calculated by the software. Volumetric measurements will be calculated in cubic millimeters.
