Figure 1. Relationship between peak velocity of stress-field translation and mechanical work in the TMJ. Vp is the peak velocity (mm/s) of stress-field translation. W (mJ) is the mechanical work. The results shown are for all mandibular activities (laterotrusion to the right and to the left, protrusion) in 15 TMJs in 10 subjects (n = 45).

Figure 2. Relationship between distance of stress-field translation and mechanical work. D is the mediolateral distance (mm) of stress-field translation during movement of the mandibular condyle. The results for all mandibular activities (laterotrusion to the right and left, protrusion) in 15 TMJs in 10 are plotted. W is the calculated work (mJ) during the movement of the condyle (n = 45).
