Definitions of linear measurements used in this analysis

Measurement	Abbreviation	Definition
AE inclination	AEIncl	Angle between the line connecting points 15 and 16, and the occlusal plane (9–10–11)
TMJ height above the occlusal plane	TMJHt	Perpendicular distance from the center of the mandibular condyle (8) to the occlusal plane of the mandibular dentition (5–6–7)
Masseter muscle orientation	MassAngle	Angle between the line connecting the origin (12) and insertion (2) of the masseter and a line describing the occlusal plane (10–11)
Medial pterygoid muscle orientation	MPAngle	Angle between the line connecting the origin (13) and insertion (3) of the medial pterygoid and a line describing the occlusal plane (10–11)
Temporalis muscle orientation	TempAngle	Angle between the line connecting the origin (14) and insertion (4) of the temporalis and a line describing the occlusal plane (10–11)
Mandibular length	MandLg	Distance from the midpoint of the mandibular condyle (10) to infradentale (1)
Glenoid length	GlenLg	Distance from the tip of the postglenoid process (18) to the anterior-most point on the articular surface of the TMJ (17)

AE, articular eminence; TMJ, temporomandibular joint.
