摘要:
Three normal adult subjects were filmed using lateral‐view, high‐speed cineradiography to measure the amount of movement of external skin points on the jaw relative to the underlying jaw bone. Metal markers were secured to the skin to simulate cantilever beam attachment points commonly utilized in the strain gauge transduction of jaw movements. Standard deviations of chin marker movement relative to the jaw ranged from 0.52 to 1.28 mm in an anterior–posterior direction and 0.67 to 2.31 mm in a superior–inferior direction. Lower lip and chin marker positions were highly correlated in the superior–inferior direction. Chin marker positions tended to be more superior and, in one subject, more anterior for labial than for nonlabial contexts. The degree of variability was not systematically different for the two different contexts.
