Until today, not all methodical details and problems concerning the exact and reproducible determination of the condylar hinge axis have been solved yet. All familiar mechanical-manual and electronically supported methods as well as computer methods of some electronical recording systems have their limitations and are partly incorrect up to now. The reason for this lies mainly in the theoretical respectively mathematical approach towards these methods. With the aim of determining a point of minimal translatory movement ("steady point") during the rotatory opening movement in the TMJ condyle, a mathematical method is presented, which calculates the 3D coordinates of the condylar rotation centers automatically, i.e. without manual manipulation of the recording system. Contrary to conventional methods, this new technique is very precise and relatively less sensitive towards superimposed translatory movements.
直到今天，关于髁突铰链轴精确且可重复测定的所有方法细节和问题仍未完全解决。所有常见的机械手动和电子辅助方法以及一些电子记录系统的计算机方法都有其局限性，并且到目前为止部分是不准确的。其原因主要在于这些方法的理论或数学方法。为了确定颞下颌关节髁突旋转开口运动期间最小平移运动点（“稳定点”），提出了一种数学方法，该方法可自动计算髁突旋转中心的三维坐标，即无需对记录系统进行手动操作。与传统方法相反，这项新技术非常精确，并且对叠加的平移运动相对不太敏感。
