Question 23 (part 2) · LDEK · Prosthodontic materials
Indicate true statements regarding hybrid ceramics:
1) modulus of elasticity 35-37 GPa, higher than the laboratory composites;
2) bending strength similar to silicate ceramics;
3) HV hardness higher than enamel;
4) it is subject to lower wear than the composites;
5) it is subject to HF etching.
Correct answer is:
2) bending strength similar to silicate ceramics;
3) HV hardness higher than enamel;
4) it is subject to lower wear than the composites;
5) it is subject to HF etching.
Correct answer is:
- A. 1,2,3.
- B. 1,4,5.
- C. 1,2,4.
- D. 1,2,4,5.
- E. all of the above mentioned.
Hint
Hybrid ceramic is a polymer-infiltrated ceramic network; place its properties between those of composite resin and glass-ceramic.
