Question 1

What is the Bennett movement in mandibular kinematics?

Accepted Answer

The bodily lateral shift of the mandible during lateral excursion

Answer

The Bennett movement is the bodily lateral shift of the mandible that occurs during lateral excursion, which is important for setting the Bennett angle on adjustable articulators.

Question 2

What distinguishes a semi-adjustable articulator from a fixed average value articulator?

Accepted Answer

Semi-adjustable articulators can be customized using interocclusal records

Answer

Semi-adjustable articulators can be customized using protrusive and lateral interocclusal records to more accurately replicate individual patient mandibular movements.

Question 3

What does the condylar inclination setting on a semi-adjustable articulator simulate?

Accepted Answer

The slope of the articular eminence relative to a horizontal reference plane

Answer

The condylar inclination simulates the slope of the articular eminence, which guides the condyle downward and forward during protrusive and lateral mandibular movements.

Question 4

In occlusion terminology, what is the working side?

Accepted Answer

The side toward which the mandible moves during lateral excursion

Answer

The working side (also called the laterotrusive or functioning side) is the side toward which the mandible moves during lateral excursion.

Question 5

What is a pantograph used for in dental prosthetics?

Accepted Answer

Recording all three-dimensional mandibular movements to program a fully adjustable articulator

Answer

A pantograph records the full three-dimensional movements of the mandible in all excursions, providing the data needed to program a fully adjustable articulator.
