Question 172 · LDEK · Occlusion
The optimal occlusion is:
1) simultaneous contact of all lateral teeth in the position of maximal intercuspation with the front tooth disclusion;
2) anterior guidance on front teeth with the disclusion of lateral teeth during the protrusion movement;
3) simultaneous contact of all lateral teeth in the position of maximal intercuspation with significantly weaker contact of the front teeth;
4) contact between the canines on the working side with the disclusion of remaining teeth during the lateral movements;
5) the upper-posterior position of the mandible heads in the articular fossa upon the maximal tooth contact.
The correct answer is:
2) anterior guidance on front teeth with the disclusion of lateral teeth during the protrusion movement;
3) simultaneous contact of all lateral teeth in the position of maximal intercuspation with significantly weaker contact of the front teeth;
4) contact between the canines on the working side with the disclusion of remaining teeth during the lateral movements;
5) the upper-posterior position of the mandible heads in the articular fossa upon the maximal tooth contact.
The correct answer is:
- A. 1,2,3.
- B. 2,3,4.
- C. 1,2,5.
- D. 2,4,5.
- E. 1,4,5.

Check whether anterior teeth should be discluded in intercuspation and how much weaker anterior contacts are than posterior ones.
