• an arm extension located between the upper half and the lower half of the split sphere ball, and
• a first locking mechanism structured and configured to lock the arm extension within the upper half and the lower half of the split sphere ball,
• wherein the split sphere housing directly attaches to the headrest mount assembly;
• a ball joint assembly comprising:
• a ball joint ball within a ball joint housing, and
• a second locking mechanism,
• wherein the ball joint assembly connects to the split sphere assembly via the arm extension;
• and
• a jaw rest assembly structured and configured to attach to the ball joint assembly,
• wherein the second locking mechanism is structured and configured to lock the jaw rest assembly in place,
• wherein the first locking mechanism and the second locking mechanism are simultaneously activated and deactivated using a single activation system,
