CDT Occlusion & Articulation 2

Question 1

What is the Bennett movement in mandibular kinematics?

Accepted Answer

The bodily lateral shift of the mandible during lateral excursion

Answer

The vertical drop of the condyle during mouth opening

Answer

The protrusive translation of both condyles forward

Answer

The closing arc of the mandible in terminal hinge position

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 use only fixed average condylar settings

Answer

Semi-adjustable articulators cannot simulate any lateral movements

Answer

Semi-adjustable articulators require a pantograph for programming

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 angle of the incisal guidance table relative to the occlusal plane

Answer

The Bennett movement angle during lateral excursion

Answer

The opening arc of the mandible during mouth opening

Question 4

In occlusion terminology, what is the working side?

Accepted Answer

The side toward which the mandible moves during lateral excursion

Answer

The non-functional side opposite the direction of chewing

Answer

The side where balancing contacts are located

Answer

The posterior region of the arch during protrusion

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

Recording the patient's centric occlusion at the correct vertical dimension

Answer

Measuring the interarch distance for denture construction

Answer

Determining ceramic shade by comparing tooth color under different lights

Question 6

What is the Christensen phenomenon observed in complete denture occlusion?

Accepted Answer

Posterior open spaces that appear between denture teeth during mandibular protrusion

Answer

An increase in vertical dimension that occurs when new dentures are fabricated

Answer

Color change in denture teeth due to staining over time

Answer

Rotation of posterior denture teeth during lateral excursion

Question 7

What is the non-working (balancing) side in lateral occlusion?

Accepted Answer

The side opposite to the direction of lateral mandibular movement

Answer

The side toward which the mandible moves during lateral excursion

Answer

The anterior segment during protrusive movements

Answer

The side bearing the highest number of occlusal contacts
