Question 244 · LDEK · Cast partial dentures
Indicate common mistakes made during construction of splint dentures:
1) combining the major connector with retention mesh;
2) no stabilizing elements positioned on the labial surface of lower incisors;
3) designing the retainer inconsistent with the insertion path;
4) planning the direct holders as precise elements in not so distant dental loss;
5) lack of sufficiently large mesh for the denture base;
6) sublingual arch located too far away from the mucosa.
The correct answer is:
2) no stabilizing elements positioned on the labial surface of lower incisors;
3) designing the retainer inconsistent with the insertion path;
4) planning the direct holders as precise elements in not so distant dental loss;
5) lack of sufficiently large mesh for the denture base;
6) sublingual arch located too far away from the mucosa.

- A. 1, 3, 4.
- B. 2, 4.
- C. only 3.
- D. 2, 6.
- E. only 5.
Hint
A splint-denture must brace periodontally weakened lower incisors from both sides, and its lingual bar must lie correctly against the mucosa.
