Question 200 (part 2) · LDEK · Post and core restorations
Modulus of elasticity is most similar to values of dentin in case of posts:
1) metallic individual;
2) individual made of ceramics;
3) metallic standard;
4) standard made from fiber glass;
5) standard made from carbon.
Correct answer is:
2) individual made of ceramics;
3) metallic standard;
4) standard made from fiber glass;
5) standard made from carbon.
Correct answer is:
- A. 1,2.
- B. 3,4,5.
- C. 2,4.
- D. 4,5.
- E. only C.
Hint
Dentin has an elastic modulus of roughly 15–20 GPa; consider which post materials come closest to it.
