Checkpoint facilitates shape anaysis for the temporomandibular joint (TMJ). The following explains how to create a population of TMJ condyles and perform a shape analysis on that population.
What is joint congruence?
Joint congruence is the measurement of two opposing joint surfaces as they relate to one another considering the 3D shape contour of each bone at their interface. For example, relating the femoral condyle to the tibial plateau or the temperomandibular condyle to the fossa.
The procrustes superimposition method calculates the procrustes average specimen, which removes scale from the specimens. The following covers the options available in Checkpoint’s Shape Analysis tab. Under “Analysis method”, select “Generalized Procrustes Analysis”.
