Flashcards in Temporomandibular Joint Deck (35):
1

which gender affected by TMD most often?

Women (4:1) (seek care more anyways)

2

common S&S of TMD

HA
orofascial pn
earache/hearing changes
neck pain

3

psychological behavior/factors of TMD

anxiety/depression
drug abuse
failed conventional therapy
major life events/crisis
vague report of pain, inconsisten/inappropriate pain
overdramatization of symptoms

4

what type of cartilage is disc?

fibrocartilage (not as strong as hyaline) not thought of as a WB joint

5

what structures attach to disc?

medial & lateral collateral ligs
post mandibular fossa
lateral pterygoid

6

muscles of mastication

medial pterygoid
lateral pterygoid
temporalis
masseter

7

nerve innervation of muscles of mastication

CN V-trigeminal
mandibular portion

8

movements of masseter M

opening

9

movements of temporalis M

retraction
closing
side to side grinding

10

movements of lateral pterygoid M

protrusion
opening
contralateral deviation
anterior rotates disk on condyle during closing

11

movemnts of medial pterygoid M

closing
deviation to opposite side

12

during opening, what motion occurs first?

rotation, then translation

13

what happens during mouth closing?

translation, then rotation (opposite of opening)

14

degree of rotation and translation

25 deg rotation
15 deg translation

15

during opening, what direction is rotation?

anteriorly,

translation inferiorly and laterally

16

what position is dysfunction in single click dysfunction?

2-3 most common

17

what position is dysfunction for dislocation/reduction?

4

18

what position is dysfunction for reciprocal click?

2 and 8

19

If the disc sticks or is bunched slightly, opening causes the condyle to move abruptly over the disc and into its normal position, resulting in a single click there may be?

partial anterior displacement (subluxation)

20

a click may occur if the disc is displaced anteriorly and/or medially, causing the condyle to override the posterior rim of the disc later than normal during mouth opening. This is referred to as?

disc displacement with reduction

21

special tests for TMD

2-3 finger/Functional knuckle test
Centric relation Pn Test
Measured Opening
TMJ Reflex
Auscultation of TMJ
Cranial Nerves

22

describe 2-3 finger test

2-3 finger of own PIP
want 45-48 mm

23

Describe Centric Relation Pain Test

Identify pain caused by malposition
Load TMJ in stable position
Pain=possible structural problem (disc torn) & co-mgmt is needed
No pain = likely functional cause that we can treat

24

what is max mouth opening?
what is fxnal mouth ROM?

50 mm max
35 mm=fxnal

25

TMJ reflex

lightly tap chin
mouth should close

26

what CN specifically should be tested?

V and VII

27

Is it acceptable to perform Grade V manipulations of TMJ?

NO

28

Differentiate active TrP vs laten TrP

Active TrP should refer pain to another area

Latent TrP corresponds to TrP charts but do not refer pain. Local pain will be present.

Latent TrP should produce a ‘snap’ or reflexive response when palpated.

29

Describe TrP Ischemic Compression treatment?

Therapy where blockage of blood occurs so a resurgence of local blood flow will occur upon release.

Find TrP compress, with a large but tolerable amount of force, for 15-30 secs and release.

Re-palpate to see if change made.

30

how does myofascial release help TMD pts?

Accomplished by relaxing contracted muscles, increasing circulation and lymphatic drainage, and stimulating the stretch reflex of muscles and overlying fascia

31

Describe Post-Isometric Relaxation

Position the patient/client appropriately for the muscle to be treated

Passively lengthen the tense muscle to the point at which the first slight increase in resistance is felt (barrier)

Have the patient/client contract the muscle gently (10%) for 6-10 secs and breathe in while you resist with equal counterforce (isometric)

Have them breathe out, “let go” and relax the muscle fully. Wait for relaxation and move to the next barrier

Repeated 3-5 times

Eye movements can be used to facilitate contraction

32

home exercises for TMD

Cervical Spine exercises Self PIR
Rest Position
Forceful tongue
Forceful tongue with opening
Proper opening
Proper opening with resistance

33

Describe Self Post-Isometric Relaxation

Relax your jaw. Gently bite down resisting with your hand.
Hold for 10 secs and then yawn while relaxing.
Let your jaw relax and open wider.
Repeat 4-5 times. Repeat 3-4 times a day.

34

Describe PIT Pterygoids

Start seated with one elbow on a table or on your knee. The same arm supports your forehead.

Place the web of the other hand on your chin.

Gently push your chin into your hand.

Take a deep breath in and hold for 10 secs.

As you exhale, relax your jaw and let it sink back.

Repeat 4-5 times. Repeat 3-4 times a day.

35

Relax postion

leave constant reminders (on cell phone, remote etc) to keep mouth in relaxed position
