Description
Yanji Gong and co-authors measured in 2024 how the height of the jaw's hinge knob above the bite plane relates to damage in the joint itself. They assessed 434 jaw joints, rebuilt them in three dimensions from scans, and grouped them by bone condition. A single angle captured the height ratio they cared about.
Joints with bone destruction showed a smaller angle, and the angle fell as the bite and jaw planes steepened. A computer stress model then moved the hinge and tilted the planes in silico. Stress rose when the knob sat closer to the bite plane and when the planes steepened. The authors advise clinicians to check this ratio before overload sets in. Adjusting the bite plane's tilt may unload the joint.
