Question 41 · LDEK · Class II malocclusions
The morphological posterior position of the mandible is characterized by:
1) inhibition of anterior mandibular growth;
2) elongation of the mandibular ramus;
3) elongation of the lower facial segment;
4) retrusion of the chin beyond the biometrical field;
5) shortened mandibular corpus.
The correct answer is:
2) elongation of the mandibular ramus;
3) elongation of the lower facial segment;
4) retrusion of the chin beyond the biometrical field;
5) shortened mandibular corpus.
The correct answer is:
- A. 1,2.
- B. 1,2,3.
- C. 1,3,4,5.
- D. 2,3,4,5.
- E. all the above.
Hint
In morphological retrognathism the mandible is genuinely small; consider which mandibular dimensions are reduced, including the ramus.
