Temporomandibular joint articulations on working side during chewing in adult females with cross?bite and mandibular asymmetry

This study aimed to investigate whether/how the working?side condylar movement irregularity and articular spaces during chewing differ between patients with mandibular asymmetry/cross?bite and control subjects. The cross?bite group and the control group consisted of 10 adult female patients and 10 adult female subjects, respectively. They performed unilateral gum?chewing. The mandibular movements were recorded using a video?based opto?electronic system. The 3D articular surface of the TMJ for each individual was reconstructed using CT/MRI data. For local condylar points, the normalised jerk cost (NJC) towards normal direction to the condylar surface, the angle between tangential velocity vector and condylar long axis and intra?articular space were measured. Three rotatory ang…
