TMD

Question 1

These muscles help close the mouth

Answer 1

Master, temporalis, medial pterygoid, and superior fibers of lateral pterygoid

Question 2

These muscles open the mouth (3)

Answer 2

Inferior fibers of lateral pterygoid, suprahyoids, infrahyoids

Question 3

These muscle protrude the jaw

Answer 3

Master, medial pterygoid, lateral pterygoid

Question 4

These muscles are responsible for retrusion

Answer 4

Masseter, temporalis, suprahyoids(digastrics)

Question 5

Lateral excursion muscles

Answer 5

Ipsilateral temporalis and masseter, contra lateral medial and later pterygoids

Question 6

A TMJ click early in opening and late during closing suggests?

Answer 6

Anterior disc displacement

Question 7

Unable to close the mouth occurs typically after what? And is caused by what

Answer 7

After dental procedure or yawn and is caused by stretching of the lateral pterygoids and posterior disc displacement

Question 8

An S curve opening and closing pattern without pain is indicative of what?

Answer 8

Muscle imbalance or add with reduction

Question 9

An S curve with pain is indicative of what?

Answer 9

Disc involvement or capsular pain

Question 10

What three things does a deflection to one side indicate

Answer 10

1. 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

Question 11

What two scenarios will have result in deflection to the ipsilateral side?

Answer 11

ADDwoR and limited capsular mobility

Question 12

What will lateral excursion look like in both capsular tightness and ADDwoR?

Answer 12

Normal to ipsilateral side and limited to contralateral side

Question 13

What will lateral excursion in hyper mobility look like?

Answer 13

Normal to affected side and excessive to contralateral side

Question 14

What does the Cotton roll test indicate?

Answer 14

Difference between muscular and joint involvement

Question 15

Explain results of Cotten roll testing

Answer 15

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

Question 16

This is an acute lock of the jaw due to spasm of the masseter

Answer 16

Range <25 mm and is called trismus

Question 17

What is treatment for anterior disc displacement?

Answer 17

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

Question 18

Tx for posterior disc displacement

Answer 18

Same as anterior, but controlled rom exercises - avoid max opening

Use longitudinal distraction

Question 19

Tx of Myofascial pain of the TMJ

Answer 19

Tx of electrophysical agents, exercises, joint mobilizations, postural correction, isometric depression exercise

TPDN

Spray and stretch

Aerobic conditioning

Question 20

Tx for trismus (limited mouth opening due to trauma or stressful event)

Answer 20

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

Question 21

Condylar remodeling exercises

Answer 21

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
