If they are thrown into a spasm, what do you do?! Lidocaine anesthesia without epi Like a gow gates…
how do you check the SCM?
look to see if it’s like a TENDON? is it stress from holding up the head.
Splenius captius and trapezius- talk about posture
Can you palpate the splines captious?
if you push hard enough. Posterior to the attachment from the SCM
normal range of mouth opening?
53-58 mm
limited range of mouth opening?
what can you do if the lateral pterygoid spasms?

no
Can you palpate the splines captious?
if you push hard enough. Posterior to the attachment from the SCM
any lateral movement
8 mm- about the size of your central incisor
T/F? If the condition becomes chronic, the posterior zone continues to thin, which perpetuates the anterior movement, causing a second click
true
Can you use pano for joint?

put film on one side and have the patient open and close.
OPEN lock?? reduce it one at a time- not in occlusion with the non drilling

no
what is reciprocal clicking?
when a click is heard upon opening AND closing
what is the 2nd click on reciprocal clicking caused by?
result of the lengthening of the retrodiscal lamina; during the final stages of closing, the lamina decreases its pull and the disc once again slips anteriorly
**so second click- from lengthening of the retrodiscal lamina during final stages of closing!!!*
what is costen’s syndrome?
