Question 150 · LDEK · Model analysis
In the transversal symmetry analysis regarding the upper dental arch the palatal suture line is used. This line is coincident with the sagittal midline line and is located by using:
1) anterior point situated between central incisors;
2) anterior point situated in the middle of the incisive papilla;
3) anterior point situated on the intersection of the second pair of palatal folds with the palatal suture;
4) posterior point situated on the border between the hard and soft palate between palatine foveae on the palatal suture;
5) posterior point defined by the tuberal line.
The correct answer is:
2) anterior point situated in the middle of the incisive papilla;
3) anterior point situated on the intersection of the second pair of palatal folds with the palatal suture;
4) posterior point situated on the border between the hard and soft palate between palatine foveae on the palatal suture;
5) posterior point defined by the tuberal line.
The correct answer is:
- A. 1,4.
- B. 2,4.
- C. 2,5.
- D. 3,4.
- E. 1,5.

Choose palatal landmarks that lie on the suture itself and do not depend on tooth positions.
