TMD Flashcards
(21 cards)
These muscles help close the mouth
Master, temporalis, medial pterygoid, and superior fibers of lateral pterygoid
These muscles open the mouth (3)
Inferior fibers of lateral pterygoid, suprahyoids, infrahyoids
These muscle protrude the jaw
Master, medial pterygoid, lateral pterygoid
These muscles are responsible for retrusion
Masseter, temporalis, suprahyoids(digastrics)
Lateral excursion muscles
Ipsilateral temporalis and masseter, contra lateral medial and later pterygoids
A TMJ click early in opening and late during closing suggests?
Anterior disc displacement
Unable to close the mouth occurs typically after what? And is caused by what
After dental procedure or yawn and is caused by stretching of the lateral pterygoids and posterior disc displacement
An S curve opening and closing pattern without pain is indicative of what?
Muscle imbalance or add with reduction
An S curve with pain is indicative of what?
Disc involvement or capsular pain
What three things does a deflection to one side indicate
- It can be indicative of ADD without R with deflection occurring ipsilateral
2 it can indicate of limited capsular mobility with deflection to ipsilateral side
3 hyper mobility of the contra lateral side
What two scenarios will have result in deflection to the ipsilateral side?
ADDwoR and limited capsular mobility
What will lateral excursion look like in both capsular tightness and ADDwoR?
Normal to ipsilateral side and limited to contralateral side
What will lateral excursion in hyper mobility look like?
Normal to affected side and excessive to contralateral side
What does the Cotton roll test indicate?
Difference between muscular and joint involvement
Explain results of Cotten roll testing
Bite down on Cotten roll on painful side:
Ipsilateral pain- muscular
If pain decreases- joint related
Then test non painful side
It should increase pain on painful side if joint related
This is an acute lock of the jaw due to spasm of the masseter
Range <25 mm and is called trismus
What is treatment for anterior disc displacement?
Electro physical agents
Manual techniques
Education on posture, jaw position, avoiding clicks
Exercise: open as wide as possible, close with protrusion to touch front teeth together
Tx for posterior disc displacement
Same as anterior, but controlled rom exercises - avoid max opening
Use longitudinal distraction
Tx of Myofascial pain of the TMJ
Tx of electrophysical agents, exercises, joint mobilizations, postural correction, isometric depression exercise
TPDN
Spray and stretch
Aerobic conditioning
Tx for trismus (limited mouth opening due to trauma or stressful event)
Ease anxiety with education, relaxation, active opening with heat, US, TENS, STM, soft diet for 1-2 weeks, spray and stretch, resisted mouth opening isometric
Condylar remodeling exercises
Lightly Bite rubber tubing with incisors, then translate the tubing to contra lateral side. If no pain then bit down after lateral translation and maintain bite moving to middle position. Can do this for protrusion
