cardinal signs of TMD
orofascail pain
crepitus
restricted jaw movment
TMD osteoarthritis
degernative changes
highly used joint-thats why there is a disc for extra protection
diffuse pain that increases when bitting firm foods
decreased ROM, stiffness
morning pain that decreases as day goes on
weakness and atrophy of muscles of masticaption
CREPTIUS is halmark for OA
grinding/clenching increases wear
goals decrease inflammation and pain, preserve and prevent further degeneration
strengthen supporting muscles, massage to increase bloodflow and healing
night guard if grinding
TMD: disc displacement with reduction
anterior disc displacement is the most common
instability in ligaments supporting disc
inflamamtion in the joint space
click when opening= reduction
click when closeing=displacment
CLICKING
TMD closed lock
open lock
closed lock can not fully open the jaw, it is locked due to anterior displacment of the disc
Tx j stroke: caudal distraction to reposition the disc, followed by a caudal anterior glide
open lock
can not close jaw due to posterior displacment of the disc
much less common
will often present to emergency soon after locked, more uncomrftable
cuadal distraction, posterior cuadal glide
TMD hypomobility syndrome
decreased ROM, localized pain at end range, signs of contracture, Hx of truama, deviation towards affected side, may have secondary myofascial syndrom
manual therapy: streching, soft tissue techniques, mobilizations, strengthening,
TMD hypermobility syndrome
excessive anterior translation, increased ROm > 50mm of opening
generalized laxity, pain with opening, deviation towards unaffected side
ay have joint nose at end range
TMD myofascial syndrome
pain that increases with opening, no joint noise, traumatic or insidious, tirgger points may result in referred pain to other ares
may result in decreased ROM due to spasm and pain
trigger point release
streching
