Question 97 · LDEK · Occlusion
The optimal occlusion scheme assumes:
1) contact between the canines on the working side with the disclusion of the remaining teeth during the lateral movements;
2) anterior guidance on the front teeth with the disclusion of lateral teeth during the protrusion movement;
3) simultaneous contact of all lateral teeth in the position of the maximal intercuspation with a significantly weaker contact of the front teeth;
4) simultaneous contact of all lateral teeth in the position of the maximal intercuspation with the front tooth disclusion;
5) upper-posterior position of the mandible heads in the maximal tooth contact in the articular fossa.
The correct answer is:
2) anterior guidance on the front teeth with the disclusion of lateral teeth during the protrusion movement;
3) simultaneous contact of all lateral teeth in the position of the maximal intercuspation with a significantly weaker contact of the front teeth;
4) simultaneous contact of all lateral teeth in the position of the maximal intercuspation with the front tooth disclusion;
5) upper-posterior position of the mandible heads in the maximal tooth contact in the articular fossa.
The correct answer is:
- A. 1,2,3.
- B. 1,2,4.
- C. 1,2,5.
- D. 2,4,5.
- E. 1,4,5.
Hint
Recall mutually protected occlusion — posteriors protect anteriors in intercuspation, anteriors guide excursions — and the condyle position in the fossa.
