Answer:

midway between angles of mandible or at a level 1 and 1/2 inches below the mandibular symphysis Question 2: Where is the CR directed for the AP axial (modified Towne) projection for Zygomatic Arches?

Answer:

center 1 inch superior to the nasion to exit at the level of the gonion Question 3: What positioning line is parallel to the IR for the oblique inferosuperior (tangential) projection of the Zygomatic Arches?

Answer:

IOML Question 4: Which way and how much is the CR angled for the axiolateral oblique (modified Law)?

Answer:

15 degree caudad

Question 5: What degree of rotation is required for a general survey of the mandible in the axiolateral oblique?

Answer:

10-15 degrees Question 6: Which positioning line is perpendicular in the PA (modified waters) projection for the mandible?

Answer:

LML Question 7: What positioning line is perpendicular to the IR in the parietoacanthial (Waters) projection of the Zygomatic Arches?

Answer:

MML

Question 8: Where is the CR centered for the PA mandible?

Answer:

to exit at the junction of the lips Question 9: How is the head positioned for the oblique inferosuperior (tangential) projection Zygomatic Arches?

Answer:

rotate head 15 degrees toward side to be examined; also tilt chin 15 degrees toward side of interest

Question 10: Where does the CR enter for the AP Axial (Towne) for the mandible?

Answer:

1" superior to the glabella Question 11: For an AP Axial (Towne) method of the mandible what is the caudal angle range?

Answer:

35 degrees if OML perpendicular to IR and 42 degrees if IOML is perpendicular to IR Question 12: From the true lateral position how much and which way is the face rotated for the axiolateral oblique (modified Law)?

Answer:

rotate face toward the IR 15 degrees

Question 13: How much head rotation on the axiolateral oblique is required to best demonstrate the mentum?

Answer:

45 degree rotation Question 14: Where is the CR directed for the axiolateral oblique (modified Law)?
