Table 1

Summary of associated mandibular coordinates relative to physiologic parameters, determined by simultaneous monitoring of masticatory muscle activity.

	Right posterior jaw	Incisal point	Right posterior jaw
Physiologic rest	2.5 mm inferior to CO, and 0.3 mm anterior.	4.4 mm inferior to CO, 0.1 anterior and to the right.	2.2 mm inferior to CO, and 0.3 mm anterior.
Maximal physiologic opening	3.6 mm inferior to CO, 0.3 mm to the right, and 1.0 mm inferior to physiologic rest.	6.2 mm inferior to centric occlusion (CO), 0.5 m to the right.	3.3 mm inferior to CO, 0.3 mm to the right of CO, and 1.1 mm inferior to physiologic rest
Maximal physiologic closing	0.1 mm inferior to CO, 0.2 mm to the right of CO, and 2.1 mm superior to physiologic rest.	2.3 mm inferior to CO, 0.2 mm to the right of CO, and 2.1 mm superior to physiologic rest.	0.1 mm inferior to CO, 0.2 mm to the right of CO, and 2.1 mm superior to physiologic rest.
Maximal physiologic protrusion	2.2 mm inferior to CO, 0.2 mm to the right of CO, and 1.7 mm anterior to CO.	4.4 mm inferior to CO, 0.6 mm to the right of CO, 1.2 mm anterior to CO, and 1.0 mm anterior to trajectory.	1.8 mm inferior to CO, 0.2 mm to the right of CO, and 0.9 mm anterior to CO.
