Define temporomandibular dysfunction (TMD) - ✔✔Group of disorders of

the temporomandibular joint or its musculature (hence we say TMD not

TMJD as that is specific to the joint problem)

Aetiology of TMJD - ✔✔-Anatomic (including occlusion and TMJ)

-Neuromuscular (muscle problems)

-Psychological (stress/anxiety/other issues)

Factors that predispose, initiate or perpetuate/sustain TMD -

✔✔Predispose:

-Systemic: tetanus, osteoporosis (generalised), inflammatory conditions

-Psychological: *Type A personality* (always stressed)

-*Structural: aplasia of joint - no joint at all* = causes limitation of joint

--> can be issues reg. the disk size, joint dislocation



Initiate:

-*Trauma* (blow on the jaw/fracture of condylar process)

-Overload

-Parafunction (grinding of teeth - *bruxism**)



Perpetuate:

-Behavioural (biting nails, pens)

-*Stress*

-*General health* (rheumatoid arthritis or general arthritis)

-Social

2 types of TMD - ✔✔-Myogenic (muscle-associated) --> can be treated by

dentists

-Arthralgic (joint-associated) --> can't really be treated by dentists

Temporomandibular joint disorders - ✔✔-Artritides (i.e. any of several

inflammation of joints)

--> Osteoarthritis

-Jaw fracture esp condylar process

-Congenital or developmental disorders: aplasia/hypo/hyper or neoplasia of

muscle or joint

-Ankylosis (of joint = stiffness of joint due to abnormal adhesion of the

bones - can be due fracturing of condyle)



-Best to refer these patients because these are related to other problems

(almost like secondary TMD due to other conditions)

Masticatory muscle disorders (i.e. myogenic TMD) - ✔✔These muscle

disorders can affect any muscle of the body inc. the muscles of mastication

and when it does it is myogenic temporomandibular dysfunction
