c) Goal is to have mirror at 45 degrees to the teeth and camera 45
degrees to the mirror. 45 degrees + 45 degrees = 90 degrees to the
teeth.
d) Square up camera, move about five inches away; focus, then shoot.
Hint, just before taking the picture ask patient to open their widest if
mirror angle is a problem.
6) UPPER OCCLUSAL:
a) Approach from head of the dental chair (around 12 O'clock).
b) To avoid the top teeth from blocking the mirror, lean forward
looking back at the mirror.
c) Get arch in view, focus off of the occlusal surface of a premolar,
reframe to get arch.
7) RIGHT BUCCAL CORRIDOR:
a) Insert retractor in patients left move it toward the midline. This is in
place to hold the lips apart.
b) Insert the wire retractor in patient's right. Insert the buccal mirror;
have the patient remove the RIGHT retractor.
c) Retract with the mirror and adjust so the line of occlusion parallels
the mirror. Retract mirror to get good view of teeth. Hint: Do not
push mirror too deep in or fulcrum off of the gingiva, it hurts! The
loose part of the cheek will often retract quite far.
d) Move camera in about 5 inches away and parallel it to the line of
occlusion you see in the mirror.
e) Ideally, you want to see all of the posterior teeth to ½ of tooth
number nine. The left buccal picture would see half of tooth #8.
