Effects of Condylar Elastic Properties to Temporomandibular Joint Stress

Figure 1

An illustration of the ultrasonic measurement process of sheep condyle. (a) Anatomic sketch of sheep mandible and condyle. (b) Condyle sample prepared for ultrasonic measurement. (c) Two-dimensional illustration of the bone material cut away so that 𝑣_13/13 can be measured. (d) A three-dimensional sketch of the bone sample after all the cuts have been made (shown as hatched parts) as well as the measurement direction for each 𝑣. 1 was the antero-posterior direction, 2 was the vertical direction, and 3 was the mesio-lateral direction. indicates longitudinal wave speed, which was measured with the generation and sensing transducer in line. indicates the transverse wave speed measured with the generation and sensing transducer at a right angle.
