Study Notes
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.
Test your knowledge on the functions of articulators, facebow analysis, determinants of mandibular movements, and condylar guidance in dental occlusion.
