A

to preserve what remains

26

straight

27
Q

Etiology of TMD

A

normal function plus an event leads to physiologic tolerance leading to TMD symptoms

28
Q

How occlusion relates to TMD

A

Introduction of an acute condition

Presence of orthopedic instability

29
Q

Orthopedic stability

A

MI position is in harmony w/ musculoskeletally stable position of condyles in fossa

30
Q

True or false: Dentist should provide dental therapy if there are any TMD symptoms

A

False: only if occlusal interferences created the symptoms

31
