Question 81 · LDEK · Complete dentures
Indicate the true statements concerning the artificial teeth arrangement in complete dentures:
1) biomechanically-wise, the optimal model of occlusion involves the maximal and simultaneous contact of the occlusal surfaces of teeth with minimal muscle tension;
2) the aim is to achieve a balanced muscle activity through correlating dentures’ retention and the proper arrangement of the occlusal surface;
3) the aim is to form dental arches in such a way so as to achieve a uniform occlusal contact between upper and lower teeth;
4) in general, in reconstruction of dentition with complete dentures, the concept of balanced occlusion applies, which involves the elimination of the so-called Christensen’s phenomenon;
5) balanced occlusion can be achieved with retaining the Christensen’s phenomenon by arranging the occlusal surface by means of the calotte method;
6) in the case of great discrepancy in size of alveolar ridges, the artificial teeth arrangement according to the static theories is indicated.
The correct answer is:
2) the aim is to achieve a balanced muscle activity through correlating dentures’ retention and the proper arrangement of the occlusal surface;

5) balanced occlusion can be achieved with retaining the Christensen’s phenomenon by arranging the occlusal surface by means of the calotte method;
6) in the case of great discrepancy in size of alveolar ridges, the artificial teeth arrangement according to the static theories is indicated.
The correct answer is:
- A. 1,2,3,6.
- B. 1,2,3,4.
- C. 2,3,5.
- D. 3,4,5,6.
- E. 2,4,6.
Hint
Recall what compensating curves and a spherical calotte do to the Christensen gap, and which set-up is used for large ridge discrepancies.
