Definition
centric occlusion
Term
What action by the patient would force the teeth into centric occlusion?>
Definition
swallowing
Term
How do you evaluate lateral occlusion?
Definition
Have patient in CR move the mandible R or L until the canines on either side are in a cusp-to-cusp relationship
Term
For Lateral occlusion, the side that the mandible has been moved is termed?
Definition
The working side
Term
What are the 3 traits of the non-working side in lateral occlusion?
Definition
1. not in occlusion
2. balancing side
3. has balancing interference if the teeth contact
