There is no specific cause to TMD, but there are contributing factors
Predisposing factors
Initiating factors
Perpetuating factors
True
5 Predisposing factors for TMD:
Systemic hypermobility (needs more evidence)
Psychosocial factors
Hx of injury
Oral habits
Dental occlusion (rare, 15%)
2 Initiating factors TMD
Direct trauma
Repetitive micro trauma (clenching, grinding, fingernail biting)

What is the best image for seeing the disc?
What is the best image for imaging bone?
What is the best for arthritis/bone?
MRI
X-ray
X-ray
When a jaw deflects to one side, is this muscle or joint?
Joint
*ADD w/o reduction
Poor occlusion is a common cause of TMD
False
*15%
NTI is used for what?
Myalgia (muscle pain)
*anterior bite has less muscle contraction, but it will still put pressure on the condyles
If the occlusion on a stabilization splint is balanced by a splint, but the pain is locking/knocking/popping and painful what is the correct option?
Reposition Forward with a Flange (anterior repositioning device)
*listed for other info

No
What is the most important part of the Exam?
Hx
What is the main function of the Lateral Pterygoid?
Protrusion
Lateral excursions
*also depressor
Does Anterior disc displacement w/ reduction limit opening?
No
*only w/o
If you have a joint problem can you also have a muscle problem?
Of course
*most pts have 4-5
If you have a limited opening with a soft infeel you have a…
Muscle problem
