Table 1 Definition of linear, angular and volumetric measurements

From: Comprehensive 3D analysis of condylar morphology in adults with different skeletal patterns – a cross-sectional study

Measurement Abbreviation Definition
Linear
 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
Angular
 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
Volumetric
 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
