name some TMD diseases
TMJ dysfunction
jaw dislocation

rheumatoid arthritis
traumatic damage
ankylosis
tumours
what are the components of TMD
muscular
mechanical
psychological
trauma
what is the aetiology of TMD
microtrauma
macrotrauma
occlusal factors
anatomical factors
what are the symptoms of TMD
pain
reduced mobility
TMJ clicking and locking
what makes up the TMJ
glenoid fossa
condylar head
articular disc
lateral ligament
inner surface of capsule
synovial membrane
what movement does the upper compartment undergo
translation
what movement does the lower compartment undergo
rotation
what is the articular cartilage made of
chondrocytes
collagen fibres in proteoglycan matrix
what is the cause of TMJ pain
compressive forces can damage proteoglycans protecting the collagen
inflammation then produces proteases and hyaluronidase
what is the conservative management of TMJ dysfunction
counselling
pain management
joint rest
physical therapy
restoration of occlusal stability
what are the functions of a bite appliance
eliminate occlusal interferences
prevent joint head from rotating so far posteriorly in glenoid fossa
reduce loading on TMJ
what are the different arthroscopic procedures
diagnosis
biopsy
lysis and lavage
disc reduction
removal of loose bodies
eminectomy
name some intra and post op complications with arthroscopy
iatrogenic scuffing
broken instruments
middle ear perforation
haemorrhage
infection
disocclusion
perforation of tympanic membrane
what is the post-op management after arthroscopy
joint rest
pain management
physical therapy
restoration of occlusal stability
what are the indications for TMJ reconstruction
joint deterioration
ankylosis
developmental deformity
tumours
