Question 1 · LDEK · Complete dentures
Indicate the basic principles of articulating methods used for the tooth arrangement in complete dentures:
1) achieving bilaterally balanced occlusion and eliminating Christensen’s phenomenon;
2) achieving unbalanced occlusion and retaining Christensen’s phenomenon;
3) basic element influencing the direction of jaw movements is the temporomandibular joint; whereas chewing movements are rotary (circular);
4) articulators simulating jaw movements are indicated;
5) during mastication vertical movements prevail, and therefore simple occluders are indicated;
6) cusp teeth are used;
7) cuspless teeth are indicated;
8) artificial teeth are positioned to the curve of Spee and the curve of Monson;
9) excluding the anterior teeth with the contact in the central occlusion through creating the so-called occlusal area.
The correct answer is:
2) achieving unbalanced occlusion and retaining Christensen’s phenomenon;
3) basic element influencing the direction of jaw movements is the temporomandibular joint; whereas chewing movements are rotary (circular);
4) articulators simulating jaw movements are indicated;
5) during mastication vertical movements prevail, and therefore simple occluders are indicated;
6) cusp teeth are used;
7) cuspless teeth are indicated;
8) artificial teeth are positioned to the curve of Spee and the curve of Monson;
9) excluding the anterior teeth with the contact in the central occlusion through creating the so-called occlusal area.
The correct answer is:
- A. 1,3,5,6,8.
- B. 2,3,5,7,9.
- C. 1,3,4,6,8.
- D. 2,5,6,8,9.
- E. 1,4,6,8,9.
Hint
Dynamic set-up methods assume the TMJ guides circular chewing strokes; think what that requires from the occlusion, the teeth and the instrument.
