  • Occlusal therapy:-altering the mandibular position,  the occlusal contact pattern, Or both of the teeth.
  • It can be divided into two types:
  • Reversible
  • Irreversible
  • Reversible occlusal therapy-
  • It temporarily alters the pt’s occlusal condition – an occlusal appliance.
  • offers optimum condyle-disc-fossa relationship for the patient- thus provides orthopaedic stability. The orthopaedic stability is maintained only while the appliance is being worn; therefore it is considered to be reversible treatment.


  • Patient awareness
  • emotional stress – Most parafunctional activity is subconscious; therefore pts are generally unaware of it.
  • Restrictive use:
  • Pain in the masticatory system- limits the functional range of mandibular movements-. painful movements should be avoided:
  • because they are associated with further damage to structures.
  • enhance the symptoms of the disorder through central excitatory effects and cyclic muscle pain.
  • Pts are instructed to function within a painless range of movement.
  •                      A general rule is “if it hurts, don’t do it”
  •  The pt is encouraged to eat softer foods, take smaller bites and generally chew slowly.
