Question 102 (part 2) · LDEK · Complete dentures
Supple 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 oral cavity as class 4:
1) well-defined alveolar processes and high-arched palate;
2) smooth, resilient, unmovable mucosa, ligament attachments localized at the base of alveolar processes;
3) atrophy of the bone basal seat area, flat palate;
4) maxillary tuberosities seemingly well-formed, soft, movable;
5) alveolar ridge is movable, displaceable, resembling a rooster comb;
6) alveolar processes seemingly well-formed, movable;
7) mucosa in the whole area is flabby, expanded, immovable;
8) soft basal seat area shows different density and susceptibility to pressure.
Correct answer is:
2) smooth, resilient, unmovable mucosa, ligament attachments localized at the base of alveolar processes;
3) atrophy of the bone basal seat area, flat palate;
4) maxillary tuberosities seemingly well-formed, soft, movable;
5) alveolar ridge is movable, displaceable, resembling a rooster comb;
6) alveolar processes seemingly well-formed, movable;
7) mucosa in the whole area is flabby, expanded, immovable;
8) soft basal seat area shows different density and susceptibility to pressure.
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
Class IV is a mixed basal seat: atrophic bone combined with soft, flabby, movable areas of differing compressibility.
