what is the angle for the PA Caldwell for mandible?
20 to 25 degrees cephalad to exit acanthion
what is the angle for the PA mandible projection?
no angle
where is the CR for a Towne for mandible imaging?
35-40 degrees caudal centered to glabella to pass through each ramus
what direction and degree are the angles for Axiolateral Mandibles?
25 degrees cephalad to pass through the region of interest
what’s the relationship of the mandibular body to the IR for axiolateral views?
no overlap of the ramus by opposite side of mandible, no elongation or foreshortening of ramus or body, no superimposition of the ramus by the cervical spine
axiolateral obliques (for mandibles): what position for what anatomy?
goal to place desired portion of the mandible parallel with the IR
ramus = head in true lateral
body = rotate head 30 degrees toward IR
symphysis (mentum) = rotate head 45 degrees toward IR
what method/image is this?
AP axial (townes) mandible
