(Created page with "==Introduction== The origins of this research can be traced back to around 1995, stemming from a series of studies by Lund, Widmer, and Feine, with a particularly interesting article for the era in which it was written: 'Validity of Diagnostic and Monitoring Tests Used for Temporomandibular Disorders' <ref>J P Lund, C G Widmer, J S Feine. Validity of diagnostic and monitoring tests used for temporomandibular disorders. J Dent Res. 1995 Apr;74(4):1133-43. doi: 10.1177/00...")

In this chapter, it has been shown how clinicians are very distant and detached from the bioengineering genesis of a diagnostic instrument they themselves use for diagnosis. We have demonstrated that the Sirognathograph along with all other similar instruments such as the [https://www.myotronics.com/k7x-evaluation-system/ Kinesiograph K7] are not three-dimensional kinematic replicators because they lose 3 degrees of freedom but above all, they are not able to identify a geometric hinge axis on which all rehabilitative gnathology is based. Therefore, in the next chapter, we will delve into this fascinating, inflated, and mysterious Condylar Hinge Axis to understand if it is clinically useful or just a source of doubt and controversy. This intermediate chapter will help us understand in detail why the RDC also eliminated the analysis of the Pantographic Replicability Index (RPI).<ref>James M. Shields, Joseph A. Clayton, Larry D.

<br />{{q2|......but then would you have eliminated the evaluation of masticatory kinematics through electrognathographs from the clinical diagnosis of TMDs?|.....I would have eliminated electrognathography as a rehabilitative gnathological process due to engineering limitations that restrict the gnathological requirements. I would have eliminated it in the diagnosis of TMDs for the same reasons but would have kept it for differential diagnosis in Orofacial Pains that overlap with cognitive, neurodegenerative, and demyelinating neurological pathologies.}}
