    • A method an apparatus for recording and reproducing the path of insertion of a cast on a dental surveyor uses an iterative method to enable rapid equalization of the height of three points on the cast by first rotating the table on which the cast is situated about a spindle supported by two mutually perpendicular pivotal adjustment arms so that a line connecting two of the points a,b is as close as possible to being parallel with a long axis of a generally horizontal one of the pivotal adjustment arms, pivoting the horizontal adjustment arm so that points a,b are at an equal height, pivoting the generally vertical adjustment arm so that point a and a third point c are at an equal height, readjusting the horizontal adjustment arm so that points a and b are again at an equal height, readjusting the vertical adjustment arm so that points a and c are again at an equal height, and so forth until all three points are at the same height.
    • 一种用于记录和再现在牙科测量师上铸造的插入路径的装置的方法使用迭代方法,以通过首先旋转铸件所在的桌子围绕心轴来快速平衡铸件上的三个点的高度 由两个相互垂直的枢转调节臂支撑,使得连接点a,b中的两个的线尽可能地与枢转调节臂中的大致水平的一个的长轴平行,使水平调节臂枢转,使得 点a,b处于相同的高度,枢转大致垂直的调节臂,使得点a和第三点c处于相同的高度,重新调整水平调节臂,使得点a和b再次处于相等的高度,重新调整 垂直调节臂使得点a和c再次处于相同的高度,等等,直到所有三个点都处于相同的高度。
