25
STMJ is the only joint that that's resting position is dictated by other bones..
Teeth (occlusion is the last link in the kinetic chain)
26
1st 15-25 mm of opening occurs ________
primarily as a rotational motion of the condyle in the inferior joint space
27
once the collateral ligaments tauten, the opening continues as primarily a _____ ______ in the upper joint space until ____ mm is reached and the posterior and collateral ligaments are taut
translatory gliding, 35
28
opening greater than 35 mm results from _________ and further stretching applied to the posterior and collateral lig
further translation with over-rotation
29
lateral excursion occurs when the condyle and the disc of the _____ side are pulled _______ along the articular eminence
contralateral, forward downward and medially
30
during lat excursion, the condyle on the ipsilateral sid performs a minimal ____
rotation around a vertical axis and a slight lateral shift
31
where do lat excursion motions take place primarily
upper joint space
32
lat excursion:
contraction of contralateral lat pterygoid, and ipsilateral temporalis. the temporalis holds the rest position of the condyle to prevent the mandible from deviating anteriorly
33
increased FHP placs the mandible in a
more retruded position
34
if same eye, angle of mouth are elevated
craniovertebral jt problem
35
if eye and opposite angle of mouth are elevated
craniomadibular problem
36
how to palpate medial pterygoid
from the inferior edge of the ramus in supine
37
which mm should you not try to palpate
Lat pterygoid
38
why is it so important to get the temporal bone on the horizontal
mandible motions cannot normalize on an unstable base
39
Pain 1
anterior inferior synovium
40
why pain 1
inflammation, excessive anterior translation of the condyle, exaggerated mouth opening; condyle compresses the anterior synovium
41
Pain 2
anterior superior synovium
42
why pain 2
inflammation, excessive anterior translation of condyle past the inferior edge of the articular eminence; leads to chondromalacia
43
Pain 3
lateral collateral ligament
44
why pain 3
tenderness of the LCL suggests joint effusion, disc hypermobility, and possible medial disc displacement/excessive lateral condylar positioning
45
Pain 4
temporomandibular ligament
46
why pain 4
tenderness suggest progressed (moderate) hypermobility of disc, hyperactivity of the temporalis mm
47
Pain 5
posterior inferior synovium
48
why pain 5`
contact the neck of the condyle against the posterior temporal wall, dental occlusal issue, parafunctions, check C1-2!, predictive of DJD
49
Pain 6
posterior superior synovium
50
why pain 6
contact of the neck of the condyle against the posterior temporal wall, posterior synovium, AND posterior dense portion of disc, predictive of chondromalacia and DJD
51
Pain 7
posterior ligament
52
why pain 7
pain indicates anterior position of the disc, compression and insult to the posterior ligament where it is attached to the posterior dense portion of the disc, arteries. progressed anterior disc displacement, DJD
53
Pain 8
retrodiscal tissue
54
why pain 8
pain indicates anterior subluxation of the disc, progressed DJD, inflammation, bleeding, effusion (intracapsular). can lead to intra-articular adhesions that disallow reduction of the disc. disc can also be displaced medially or laterally
55
excessive anterior translation causing stretching of capsule, leading to inflammation
Pain 1, 2
56
sprain of the lateral collateral ligament or temporomandibular ligament, some degree of jt hypermobility
pain 3, 4
57
excessive posterior position of the mandible; the neck of the condyle contacting the temporal fossa
pain 5, 6
58
posterior ligament sprain and compression inside the jt; disc displacement
pain 7, 8
59
pain with resisted mouth opening strongly points to
non-reducing disc
60
in the absence of trauma to the head/mandible, the problem typically starts with
the craniovertebral spine
61
synovitis is tender to palpation at TMJ
lateral condyle or posterior compartement
62
pain with biting on opposite side
synovitis
63
how to treat synovitis
treat with long axis distractions, re-ed for controlled opening, modalities, active rest
64
T/F masticatory muscle disorders typically have joint sounds
F. they also have no history of joint sounds
65
pain with biting on the same side
masticatory muscle disorders
66
how to treat masticatory muscle disorders
controlling opening, myofascial release, POSTURAL CORRECTION of the craniocervical spine, dry needling, education on parafunction, active rest
67
what does parafunction mean
A para-functional habit or parafunctional habit is the habitual exercise of a body part in a way that is other than the most common use of that body part.
68
elongated collateral lig and retrodiscal tissues
disc displacement with reduction
69
disc lies in a medial, anterior, or lateral position at rest
disc displacement with reduction
70
condyles are posterior to the posterior region of the disc
disc displacement with reduction
71
on opening the condyle reduced back of the posterior region of the disc
disc displacement with reduction
