30
Q

1 in 3 patients that suffer whiplash will experience

A

TMJ symptoms

31
Q

TMD affects what percent of the populaton

A

10-40% of general population

32
Q

How long does it take to decrease TMD pain

A

at least 4 weeks

33
Q

for every year of TMD, how long under care

A

1 month

34
Q

TMJ depends on what 3 things

A

teeth size, position, occlusal surface alignment

35
Q

TMJ Assessment involves

A

ROM (active, passive, active resisted)

observe deviation, pain, clicks, catches, etc.

36
Q

why should you observe TMJ while seated

A

gravity and proprioception

37
Q

when checking TMJ fossa, avoid pressing firmly due to

A

patient sensitivity

38
Q

what are you feeling in TMJ palpation

A

glenoid fossa

39
Q

finger falling in second is the

A

involved side

40
Q

side the jaw initially deviates to is

A

involved side

41
Q

measurement of left and right deviation

A

> 7mm

42
Q

protrusion and retraction measurement is

A

> 6mm

43
Q

on protraction and retraction RMT, what is the side of weakness

A

side that the mandible deviates to

44
Q

what can be used for bilateral weakness o TMJ

A

helmet chin strap

45
Q

TMJ is one of the most

A

muscle imbalanced areas in the human body (chewing on one side)

46
Q

while muscle testing what are we looking for

A

weakness, failure to “lock”

47
Q

usually side with greater motion is involved side because opposite side disc is

A

not impeding condyle’s forward glide

48
Q

know the 12 signs of TMS

A

look at packet

49
Q

clenching involves what muscle

A

temporalis

50
Q

grinding involves

A

pterygoid

51
Q

what does the pterygoid do to the disc

A

pulls it forward

52
Q

equal spacing of condyle in fossa means

A

neutral jaw

53
Q

receeding gums due to

A

teeth grinding, leads to cavities

54
Q

disc displacement due to

A

direct trauma
intubation
dental work
big bite

55
Q

long time muscle imbalances due to

A

chewing on one side
AHS
sleep posture
resting head on hands

56
Q

what can TMJ issues be disguised as

A 
ear infection
fullness in ear
headache, toothache
C1 subluxation
sinus infection
57
Q

superior posterior lateral TMJ

A

disc moved anterior inferior allowing condyle to occupy space

58
Q

SPL ROM

A

jaw towards side of involvement until condyle bumps against anterior disc; may click

59
Q

if there is clicking at the end of ROM

A

do not adjust. hypermobility. fix with exercises

60
Q

TMJ with less than 3 signs/symptoms has

A

TMD

61
Q

patient with 3 or more signs/symptoms has

A

TMS

62
Q

SPL jaw LOD

A

Anterior, inferior, medial

63
Q

pathonomonic sign of anterior inferior condyle (posterior disc)

A

inability to close the teeth together on side of involvement

64
Q

anatomy of posterior disc/anterior condyle

A

disc displaced posterior, moving the condyle anterior, limiting closing mechanism

65
Q

symptoms of posterior disc

A

malocclusion, may have sudden ear pain, can open more than 20 mm, do 2-3x

66
Q

Bruxism mouthguard stages

A
  1. ) teeth guard from drug store
  2. ) heat moldable guard
  3. ) custom one from dentist
67
Q

acute injury

A

pain usually on involved side 2-3 months

68
Q

chronic injury

A

pain is opposite side of problem

69
Q

when should referral be considered

A

not getting better after 6 visits

70
Q

post adjustment management

A

avoid foods tough to chew, icing with dixie cup 5 minutes 3x a day, exercises first two weeks twice a day in direction of weakness

71
Q

what muscles should be considered

A

deep neck flexor weakness and SCM shortness

72
Q

causes of grinding

A

misalignments, muscle imbalance, stress, parasites, posture, cervical issues

73
Q

what muscles should be checked for shortening

A

SCM, scalenes, upper traps, masseter, pterygoids, temporalis
