This paper deals with the nature of mandibular hinge axis and the consequences for its application in diagnostics and treatment. The transversal hinge axis of the mandible can be characterized as an exact and true axis of pure mandibular rotation or a more or less exactly located axis as a result of a combined rotation and translation of the condyles. During opening movements of about 8 mm already an insignificant gliding of the condyles of 0.5 mm displaces the individual located hinge axis of more than 6 mm in its relation to the lower jaw. The true hinge axis as it is needed for achsiographic or pantographic registration techniques has inevitably not to be identical with the transferred axis for mounting casts in an adjustable articulator.
本文探讨了下颌铰链轴的性质及其在诊断和治疗中的应用后果。下颌的横向铰链轴可被描述为纯粹下颌旋转的精确真实轴，或者是由于髁突的旋转和平移组合而或多或少精确确定的轴。在大约8毫米的开口运动中，髁突仅0.5毫米的微小滑动就会使个体定位的铰链轴相对于下颌移动超过6毫米。轴面描记或全景描记记录技术所需的真实铰链轴必然与用于在可调式咬合架上安装模型的转移轴不一致。
