3-Dimensional Physiologic Postural Range of the Mandible: A Computerized-Assisted Technique—A Case Study

Figure 1

Adapted and modified from [26, page 9]. SEMG of the temporalis anterior (TA), masseter (MM), temporalis posterior (TP), and suprahyoid (DA) sites in combination with incisal spatial kinematics. “Maximum physiologic opening” or the bottom of the physiologic zone (incisal position 1) was determined when the suprahyoid activity was above what was determined as normal levels. The top of the zone or “maximal physiologic closing” (incisal position 3) was determined when elevator activity increased to greater than what was determined as physiologic normal levels. Physiologic rest (incisal position 2) position after 45–60 minutes of ULF-TENS.
