Dental Articulators and Mandibular Movements Quiz

Articulators in Dentistry

• The Panadent PCH model represents a semi-adjustable articulator.

Facebow in Dentistry

• A facebow is used to record the spatial relationship between the maxilla and the condyles.
• The primary purpose of a facebow is to transfer the patient's anatomy to an articulator.

Articulator Types

• A semi-adjustable articulator can be distinguished from a non-adjustable one by its ability to be adjusted for lateral condylar inclination.
• Non-adjustable articulators are fixed and cannot be adjusted for individual variations.

Mandibular Movements

• Lateral condylar inclination adjustments in articulator selection allow for simulation of individual patient variations.
• The main function of an articulator is to replicate mandibular movements and registrations.
• The relationship between the condylar head within the articular fossa and articular eminence is a determinant of mandibular movements.

Anterior Guidance

• Anterior guidance is a determinant of mandibular movements, involving the guidance of the mandible by the maxillary anterior teeth.

Incisor Guide Tables (IGT)

• Incisor Guide Tables (IGT) are used to simulate anterior guidance and guide the articulator.

Mandibular Movement Influencing Factors

• The distance between maxillary anterior teeth and condylar hinge axes influences mandibular movements.

Cusp Path Deviations

• A condition where the cusp paths traveled on the articulator are distal to those in the mouth can result from incorrect articulator settings or recordings.

Facebow Function

• The facebow allows for accurate transfer of the patient's anatomy to an articulator.
