Question 212 · LDEK · Acrylic partial dentures
In mucosa-supported dentures, without tooth-support, the settling phenomenon occurs. Indicate the signs of the phenomenon:
1) excessive contact on artificial teeth of the denture;
2) the loss of contact between opposing teeth in the denture;
3) reduced chewing efficiency;
4) functional debility of natural teeth;
5) functional overload of natural teeth and their mobility;
6) increased occlusal vertical dimension and disorders of TMJ;
7) decreased occlusal vertical dimension and disorders of TMJ;
8) the loss of clasps’ function and the need for their replacement;
9) decreased position of clasp arms and irritation of the marginal gingiva; 10) atrophy of the alveolar bone; 11) hypertrophy of the bone and mucous tissue.
The correct answer is:
2) the loss of contact between opposing teeth in the denture;
3) reduced chewing efficiency;
4) functional debility of natural teeth;
5) functional overload of natural teeth and their mobility;
6) increased occlusal vertical dimension and disorders of TMJ;
7) decreased occlusal vertical dimension and disorders of TMJ;
8) the loss of clasps’ function and the need for their replacement;
9) decreased position of clasp arms and irritation of the marginal gingiva; 10) atrophy of the alveolar bone; 11) hypertrophy of the bone and mucous tissue.
The correct answer is:
- A. 1,3,4,6,8,10.
- B. 2,3,4,7,8,11.
- C. 2,3,5,7,9,10.
- D. 3,5,7,8,10.
- E. 1,4,6,8,9,11.
Hint
A denture without tooth support sinks into resorbing tissues; follow the consequences for occlusion, clasps, natural teeth and bone.
