What is the Bennett movement in mandibular kinematics?
Answer: The bodily lateral shift of the mandible during lateral excursion
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.
What distinguishes a semi-adjustable articulator from a fixed average value articulator?
Answer: Semi-adjustable articulators can be customized using interocclusal records
Semi-adjustable articulators can be customized using protrusive and lateral interocclusal records to more accurately replicate individual patient mandibular movements.
What does the condylar inclination setting on a semi-adjustable articulator simulate?
Answer: The slope of the articular eminence relative to a horizontal reference plane
The condylar inclination simulates the slope of the articular eminence, which guides the condyle downward and forward during protrusive and lateral mandibular movements.
In occlusion terminology, what is the working side?
Answer: The side toward which the mandible moves during lateral excursion
The working side (also called the laterotrusive or functioning side) is the side toward which the mandible moves during lateral excursion.
What is a pantograph used for in dental prosthetics?
Answer: Recording all three-dimensional mandibular movements to program a fully adjustable articulator
A pantograph records the full three-dimensional movements of the mandible in all excursions, providing the data needed to program a fully adjustable articulator.
What is the Christensen phenomenon observed in complete denture occlusion?
Answer: Posterior open spaces that appear between denture teeth during mandibular protrusion
The Christensen phenomenon describes the posterior open spaces between maxillary and mandibular denture teeth during protrusion, requiring compensating curves to achieve posterior balanced occlusion.
What is the non-working (balancing) side in lateral occlusion?
Answer: The side opposite to the direction of lateral mandibular movement
The non-working side (mediotrusive or balancing side) is the side opposite to the direction of lateral mandibular movement, where balancing contacts may be designed in complete dentures.
