Question 47 · LDEK · Acrylic partial dentures
Indicate the adverse implications caused by the settling of mucosa-supported removable partial dentures:
1) loss of occlusal contact and reduced occlusal vertical dimension;
2) loss of occlusal contact and increased occlusal vertical dimension;
3) relieving the load on the remaining natural teeth;
4) overload of the remaining natural teeth;
5) shifting of the clasp arms and their disfunction;
6) alveolar bone loss;
7) tooth mobility and inflammation of the mucosa;
8) joints and muscles functional disorders.
The correct answer is:
2) loss of occlusal contact and increased occlusal vertical dimension;
3) relieving the load on the remaining natural teeth;
4) overload of the remaining natural teeth;
5) shifting of the clasp arms and their disfunction;
6) alveolar bone loss;
7) tooth mobility and inflammation of the mucosa;
8) joints and muscles functional disorders.
The correct answer is:
- A. 1,4,5,6,7,8.
- B. 2,3,6,7,8.
- C. 1,3,5,7,8.
- D. 4,5,6,7,8.
- E. 2,3,7,8.
Hint
As a tissue-borne denture sinks, ask what happens to the vertical dimension and how forces are redistributed to the remaining teeth.
