Q

describe the disc of the TMJ

A

avascular except on periphery

bears load with closing mouth

guides motion, resists compression, and provides stability

Q

normal opening for tmj

A

~3 knuckles

less than 1 = urgent referral

condyles flide anteriorly

bilateral clicking is normal

16
Q

when will you see earlier deviation without loss of functional opening

A

Hx of past trauma resulting in greater laxity

minimal to no pain

dev away from unilateral hypermobile side

click at end range on hypermobile side indicates larger displacement

ONE SIDE MOVES TOO MUCH

17
Q

when will you see end range deviation without loss of functional opening

A

no hx of trauma

minimal to no pain

gradual and less hypermobility developed bilaterally due to FHP

click at end range indicates larger displacement

BOTH SIDES MOVING TOO MUCH

18
Q

influence of FHP on TMD

A

laxity from prolonged positioning

increased tension/lengthening of some muscles

displaced anterior mandibular condyle to disc

impaired length tension of muscles

19
Q

what should you assess in and out of FHP

A

opening in neutral and FHP should be the same

swallowing in FHP and neutral should be the same

20
Q

how is displacement described

A

condyle in relation to disc

21
Q

how does anterior displacement occur

A

condyle is anterior to disc

hx of prolonged opening, trauma with sudden opening, or excessive opening

S&S = full opening with no deviation, and likely pain/limits with closing

22
Q

Rx for anterior displacement

A

dstx with post glide to reposition condule posteriorly

hope to reverse creep of capsule and ligament

MET stabilization of TMJ and neck

23
Q

lifestyle changes with anterior displacement issue

A

avoid wide opening with diet or yawn

correct posture

sleep with neck flexed and chin tucked

24
Q

other clicks/signs of hypermobility

A

early clicking upon opening- small displacement

inconsistent click

reciprocal clicking - condyle moves ahead of disc on opening and behind disc on closing

25
Q

how much posterior displacement occur

A

condyle is posterior to disc

hx of trauma with sudden closing

likely pain and limits on opening

full closing

26
Q

rx for posterior displacement

A

distx with ant glide to reposition mandibular condyle anteriorly

sleep with small neck roll for slight neck ext and opening

avoid excessive or hard chewing/grinding

possible nick splint to maintain slight opening

27
Q

PT Rx for TMD

A

POLICED

STM intra and extra orally

modalities for pain/guarding

posture edu

sit tall

maintain open packed position

oral habit modification

disphramatic breathing training

activity modification

MT - JMs and TMJ and neck for hypomobility and displacement reduction

28
Q

MET for TMD

A

TMJ typically isometrics plus neck exercises

practice resting and talking with cork between teeth

29
Q

dentist and/or MD Rx for TMD

A

splints
orthodontics
Sx

30
Q

prognosis for TMD

A

very good with proper mechanics, posture, and breathing patterns
