PPT 5 Flashcards
Who invented our articulator?
Rudolph L. Hanau, a mechanical engineer, developed the Hanau articulator (NOT A DENTIST!)
What are the 5 objectives of the Hanau articulator?
- To utilize an adjustable mechanical instrument with attached casts that will simulate mandibular movements
- To use a designed instrument similar to human anatomical guidelines (condylar fossa/path is in the upper member, condylar head/element in the lower member)
- To accept and mount the face-bow transfer record for the MAXILLARY arch
- To accept/mount the CENTRIC RELATION record for the MAND arch
- To utilize the MAX/MAND orientation of casts for clinical and laboratory procedures
What is the Bennett Calibration for?
Setting the immediate side shift
What is the Condylar guidance for?
Setting the protrusive movement
What are the incisal pin and occlusal table for?
Setting the parallelism of the articulator
Where is the fossa in the arcon articulator?
The top member has the fossa
Where are the condyles in the arcon articulator?
The bottom member has the condyles
Just as the anterior inclination is constant to the cranium, even as the mandible moves, the ______ is constant to the upper member of articulator as the lower member moves
Condylar guidance inclination
What must you be sure to do with the mounting plate?
- Make sure its the right one for your articulator
2. TIGHTEN all the way down
In what plane/whatever is the top member to the bottom member
Must be parallel to each other
Where do you set the incisal pin guide
Set at Zero (SIXTH LARGE BLACK LINE) with the pin touching the occlusal table
Where is “zero” for pin on hanau articulator?
The 6th large black line
Should you adjust your pin after setting?
NO, never
Where should the pin fall on the occlusal table?
Edge-to-edge on the marked line and runway
What is the result of loosening the centric lock on the articulator?
Changes the hinge articulator to a semi-adjustable articulator
