Question 42 · LDEK · Mandibular movements and articulators
The concept of immediate side shift involves:
1) protrusive movement of the mandible and the occurrence of centrifugal motion of the mandibular condyle on the working side;
2) protrusive movement of the mandible and the occurrence of centrifugal motion of the mandibular condyle on the balancing side;
3) lateral movement of the mandible and the occurrence of forward motion of the mandibular condyle on the balancing side;
4) lateral movement of the mandible and the occurrence of concentric motion of the mandibular condyle on the balancing side;
5) lateral movement of the mandible and the occurrence of centrifugal motion of the mandibular condyle on the working side.
The correct answer is:
2) protrusive movement of the mandible and the occurrence of centrifugal motion of the mandibular condyle on the balancing side;
3) lateral movement of the mandible and the occurrence of forward motion of the mandibular condyle on the balancing side;
4) lateral movement of the mandible and the occurrence of concentric motion of the mandibular condyle on the balancing side;
5) lateral movement of the mandible and the occurrence of centrifugal motion of the mandibular condyle on the working side.
The correct answer is:
- A. 1,3.
- B. 2,3.
- C. 3,4.
- D. only 4.
- E. only 5.
Hint
Think of the very first millimetres of a lateral excursion and which condyle shifts bodily toward the midline before travelling down the eminence.
