Clinically, useful , repeatable reference point .

Question 4

What’s mandible statues is CR and how it most be during exam ?

Answer 4

Mandible can’t be forced into centric relationship from the rest position because the patient neuromascular defense reflex would resist the applied force .
Mandible should be relaxed and gently guided into center if relation

Question 5

What’s centric occlusion?

Answer 5

It’s when mandible in centric relation
