TMJ disorders

Question 1

craniomandibular disorder

Answer 1

cmd
A group of pathologies affecting the masticatory muscles, the TMJ and related structures

Pain is commonly reported in the regions of the TMJ around the ear, head and neck

Question 2

three groups of classifying TMJ disorders

Answer 2

Muscle disorders

Disc displacement

Arthralgia arthritis arthrosis

Question 3

Articular structures

Answer 3

Condyle
Articular disc
Superior lateral pterygoid
Retrodiscal tissue

Question 4

Disc displacement with reduction

Answer 4

elongated collateral ligaments, and retrodiscal tissues

Disc lies in an anterior posterior at rest
condyles are posterior to the posterior region of the disc

On opening, the condyle reduces back over the posterior region of the disc and normal function resumes

Question 5

Disc displacement without reduction

Answer 5

elasticity of the collateral ligaments and retrodiscal tissues is lost

Condyles are unable to guide over the posterior region onto the disc

When the disc is not reduced, translation of the condyles stops as the disc is forced anteriorly

Question 6

condylar subluxation

Answer 6

occurs with hyper mobility of a joint capsule

Condyle and disc translate over the articular eminence appearing to jump forward into the maximum opening position

Question 7

Hypermobility intervention

Answer 7

Stabilization

Teach to
not open wide
Limit opening to which can be performed in the tongue up position
Lateral pole palpation
Isometric exercises
Address Muscle weakness
Mandibular muscle relaxation BFB

Question 8

hypomobility treatment

Answer 8

mobilize

Manual mobilization
Self mobilization
Intra-oral appliance mobilizing splints
Stretching

Question 9

evaluation of TMJ

Answer 9

Postural screen
Palpation also include cervical spine
Motion assessment
40-45 mm interinciscal opening
8-10 mm lateral deviation
8-10 mm protrusion

35+ is functional
