Equipment Selection Flashcards
What can simple hinge articulator do?
Hold model in ICP
Adv of anatomical articulator
Replicates jaw movement
What average values are used for anatomical articulator?
30 degree condylar angle
Straight condylar pathway
Starts CR
What can do w/ semi-adjustable anatomical articulator?
Condylar path can be adjusted between 0-60 - pathway still flat
What can do w/ fully adjustment anatomical articulator?
Custom made condylar pathways
How are models mounted on anatomical articulator?
In CR
What need to provide so models can be articulated?
Facebow record - record relationship between condyle and maxillary teeth
What is an EarBow?
Use of external auditory canal used for ease
Ojectives of occlusion for complete dentures?
Balanced occlusion
ICP=RCP
Working side contacts - balanced
Protrusion - incisors and posterior teeth
Issue restoring anterior guided tooth?
Palatal surface very important - check carefully prior to restoration
When may want to re-orgnaise occlusion in RPD pt?
If OVD not acceptable
No stable ICP
Mount in CR to re-organise
What make splint?
Ideal occlusion w/ splint
Facebow record - mount model CR
Use of facebow?
Insure incisor plane angle correct
Enable condylar angle to be recorded
Ensure correct model ‘height’ on articulator
How does mounting models change if conforming or reorganising occlusion?
Take facebow
Conforming - mount model ICP
Reorganise - mount model CR
