Question 120 · LDEK · Complete dentures
Supple’s classification is used to evaluate the tissue conditions (mucosa and bone) of a basal seat area in the edentulous mouth. Indicate the conditions that classify the edentulous oral cavity to class 4:
1) well-defined alveolar processes and high-arched palate;
2) smooth, resilient, undisplaceable mucosa, ligament attachments localized at the base of alveolar processes;
3) atrophy of the bone basal seat area, flat palate;
4) alveolar processes seemingly well-formed, movable;
5) alveolar ridge is movable, displaceable, resembling a rooster comb;
6) maxillary tuberosities seemingly well-formed, soft, movable;
7) mucosa in the whole area is flabby, expanded, displaceable;
8) soft basal seat area shows different density and susceptibility to pressure.
The correct answer is:
2) smooth, resilient, undisplaceable mucosa, ligament attachments localized at the base of alveolar processes;
3) atrophy of the bone basal seat area, flat palate;
4) alveolar processes seemingly well-formed, movable;
5) alveolar ridge is movable, displaceable, resembling a rooster comb;
6) maxillary tuberosities seemingly well-formed, soft, movable;
7) mucosa in the whole area is flabby, expanded, displaceable;
8) soft basal seat area shows different density and susceptibility to pressure.
The correct answer is:
- A. 1,2,6,8.
- B. 3,4,5,6,7.
- C. 2,3,4,5.
- D. 3,5,6,8.
- E. 1,4,5,6,8.
Hint
Supple's class 4 is the flabby, mobile basal seat — choose features describing mobile soft tissue over an atrophied bony base.
