This chapter addresses the disconnection between clinicians and the bioengineering aspects of diagnostic tools, focusing on kinematic replicators like the Sirognathograph and Kinesiograph K7. These devices, widely used for analyzing mandibular movements, lose three angular degrees of freedom, undermining their ability to accurately represent the complexity of mandibular dynamics. The chapter critiques the Research Diagnostic Criteria (RDC) for dismissing the clinical value of these tools due to perceived low validity. However, the clinical and biomechanical importance of accurately determining the transverse hinge axis (tHA) and its associated rototranslational movements is highlighted, showing that errors in tHA localization can significantly affect dental occlusion and prosthetic rehabilitation. | This chapter addresses the disconnection between clinicians and the bioengineering aspects of diagnostic tools, focusing on kinematic replicators like the Sirognathograph and Kinesiograph K7.
