Table 1 Definition of linear, angular and volumetric measurements

 Condylar depth

C depth

Shortest distance between the most posterior and the most anterior point of the condylar head

 Condylar width

C width

Shortest distance between the most lateral and the most medial point of the condylar head

 Condylar height

C height

Shortest distance between the most cranial point of the condylar head and a plane parallel to FH through the most caudal point of the mandibular notch

 Antero-posterior inclination of the condyle

C incl a-p

Angle between the FH plane and the connecting line between the most cranial and the most posterior point of the condylar head

 Medio-lateral inclination of the condyle

C incl m-l

Angle between the midsagittal plane and the connecting line between the most medial and the most lateral point of the condylar head

 Condyle

C

Condylar volume limited by a plane parallel to FH through the most caudal point of the mandibular notch

 Mandible

Mand

Total mandibular volume including the alveolar process (without teeth)

 Ratio C/Mand

C/Mand

\( \frac{condylar\ volume}{mandibular\ volume} \) × 100
