Fig. (1) Simulation of disc-condylar movement of normal TMJs shown in Cine-MRI. FIESTA parameters, TR milliseconds/TE milliseconds=133.7.0/13.8 (A) In the closed-mouth position (B) At an open-mouth position of 1.0 cm, there was onset of condylar rotation (C) At an open-mouth position of 2.0 cm, condylar translation continued (D) At an open-mouth position of 3.0 cm, there was condylar translation (E) At an open-mouth position of 4.0 cm, there was a rotational movement with a very short forward translation of the condyle (F) At an open-mouth position of 5.0 cm, (maximum mouth opening), the condyle was located slightly before the apex of the eminence.
