causing symptoms of TMD. According to the AGD, poor posture puts the spine in a position that stresses the jaw joint. In particular, the lower jaw shifts forward, causing the upper and lower teeth misalignment
During this working-side movement in the horizontal plane, the condyle does not rotate about the center of the condyle but rather the center of rotation can be visualized to be behind the condyle. • At each successive instant in time during chewing, the center of rotation shifts in space....
TMD/TMJ can be triggered by bruxism (teeth grinding or clenching) or by injury to the jaw, head, or neck muscles, such as from a heavy blow or impact. Additionally, TMJ pain may arise from genetic factors or arthritis, as well as when the disk erodes or shifts from its proper alignmen...
The compacting bolus in the BAT-area distracts and shifts the fulcrum inferiorly in the glenoid space of the condyle ipsilateral to the bolus. The compacting, ever denser food bolus also tends to transform into a novel fulcrum for a class 1 lever (Fig. 4, middle panel). Thus, both the...
Since trigger notch 166 has pivoted out of alignment with the plunger 162, however, plunger 162 shifts slightly upward to an intermediate position in which its top surface bears on the arcuate lower edges 167 of trigger 22 (compare switch 24 in FIG. 3). When plunger 162 is in its ...
Papa’s jaw dropped when Mama told him that Sister had cheated on her final exams—not to succeed but to fail. “It’s unbelievable!” he said. “Sister has always been so proud of her good grades!” “Yes, she has,” said Mama. “But it’s not unbelievable. It just shows how ...

Individual differences from these constants exist because of variations in dentition and shifts at the time of sensor installation; therefore, they should be measured in advance via devices such as intraoral 3D scanners. Figure 3. Translation of data from the molar to the anterior dental point. (...
